UK’s best garden sprayers TESTED that are heavy duty for high pressure

This article was last updated on September 9th, 2022 at 3:41 am

You probably would be surprised to know, but in my personal testing, I actually favoured a garden sprayer over a fence sprayer for some fence paints. And that goes for shed paint too. No power requirement, a reasonably even spray, and miles quicker than a brush makes this an unlikely favourite – it was just a bonus that my Spear & Jackson Pump Action Pressure Sprayer cleans up nicely and had no problems spraying the weed killer in that test too. After using my garden sprayers for so long and effectively as I have. I’d like to share a few thoughts from my experiences.

Spear & Jackson Pump Action Pressure Sprayer – my trusty sprayer I’ve used for years

But, as with all good products it would be unfair not to test and compare others. So this time round I decided on a similar sized 5 Litre garden sprayer by Ansio. However, I am absolutely justified in still naming the Spear & Jackson top dog as it proved out yet again for best garden sprayer. And seeing as the Ansio set me back a few quid more than the Spear & Jackson I won’t be changing the order of my reviews anytime soon but I’ll definitely be putting it as an alternative as apart from one super annoying total enraging flaw it was a super bit of kit too. More on that in the full tested review of the 5 Litre garden sprayer by Ansio!

I tested the Ansio 5 Litre Garden Sprayer and put it up against the best garden sprayers


So with that in mind, here are my top picks for the best garden sprayer:

Best garden sprayer: my top picks from 15 years experience and personal use:

Best garden sprayer: Spear & Jackson Pump Action Pressure Sprayer – best of the best garden sprayer and my go to for weed killers, fence paints and stains, as well as sheds. This is personally tested and proven to hold pressure for ages when spraying weed killer

Sensible alternative: Ansio 5 Litre Garden Sprayer – decent choice if the Spear and Jackson isn’t big enough (8L and 11L options) or available [personally tested and proven]

Best back-pack garden sprayer: Faithfull Pressure Sprayer Knapsack 16L – best if you need a large garden sprayer [personally tested and proven]

Commercial heavy duty pick: Faithfull Pressure Sprayer Knapsack 16L [personally tested and proven]

Budget: Garden gear pressure sprayer

What you should be considering when buying a garden sprayer

There’s a few really important things to think about when buying a garden sprayer. They are definitely not all equal. The crucial thing for me is even pressure and compression so you get an even spray. Then there’s size, container thickness, shoulder straps, pressure release valves, and all important variable nozzle settings to change your flow from a squirt right through to a full on mist. So with that in mind let’s look a little close at some of those issues.


Size is an important factor – are you looking for a small medium or large sprayer? If it’s large there’s no question you go for the the Faithfull Pressure Sprayer Knapsack 16L. If you’re after mid size for weed killer for example, then the Spear & Jackson or the Hozelock sprayer is ideal.

The Faithfull is definitely for commercial work and it really packs a punch too!

Pressure translates into spray

It’s important to remember not all pressure pots are equal. The more pressure your garden sprayer can hold, the better it’ll be equipped to provide an even spray. My Spear and Jackson is considerably more powerful than the average. And on that note, you have to watch for over pressurising your sprayer – in the past I’ve broken cheap ones pumping them too much. Just wait for resistance to build as you pump – you’ll feel it and you’ll feel what pressure is sensible. Then you can adjust the nozzle to workout how you want to spray. Let’s look at the adjustable nozzle and I’ll include a video of the pressure and the nozzle adjustment below.

Adjustable nozzle for a variable spray setting

One of the biggest things on the spray nozzles is the adjustment. My Spear and Jackson really works for that. In fact it is extremely sensitive and therefore takes a bit of getting used to. Even though I’ve used mine for years this still happens:

As you can see it doesn’t take much getting used to and very easy to use – but remember not to spray weeds with a mist too fine in windy conditions as a herbicide in the lungs is not good! So always aim on the cautious side, and with Creocote I don’t care how rough it looks, I let it spurt out – there’s no way I am ingesting those fumes again. I felt really rough even though I wore a mask. So now I let it squirt out and run. No problem with that. I do not set the nozzle fine:

Here are, what we consider, the seven best garden sprayers reviewed for you. We’ve chosen products that we think give you the best value for money, and that are affordable for everyone.

Pressure release valve

The next thing to consider is the pressure release valve. You want to release the pressure gradually as the main pump section can be very difficult to open if there’s too much pressure. Whereas the smaller valve is relatively easier to open and control. Here’s a close up look at that valve:

Shoulder strap

Most come with a shoulder strap but some are too short. The cheap garden sprayer I have doesn’t comfortably loop over my other shoulder, whereas the Spear and Jackson has a longer strap and is far more comfortable to wear – it’s only when you test many of these sprayers that you realise just how useful they can be! Here is me demonstrating just how long this strap really is – it’ll comfortably go over any shoulder:

Spear & Jackson Pump Action Pressure Sprayer – decent length strap comfortably sits on shoulder

It’s got variable straps too so if you’re shorter or prefer it up higher then no problem at all.

With those points looked over – here’s a rundown of the best garden sprayers:

When I initially wrote this review a couple of years ago I had this best-selling product from Spear & Jackson. It is our first garden sprayer review and it is available on Amazon and is still the best garden sprayer.
 It has a 5 litre translucent tank that has markings to help you get the right mix of any non-viscous soluble or water based products that you wish to use. You can even shoot Creocote through this garden sprayer as I demonstrate here:

Connected to the tank by a 1300mm hose is the plastic watering lance that measures 560mm, giving you a decent amount of reach for getting at those hard to water spots. The wand is adjustable and will give you either a jet, wide spray or a fine mist. The jet isn’t super powerful but for weed killer, specifically pet friendly weed killer, it is superb and holds a decent spray for ages, just take a look:

The trigger can be locked in the ‘on’ position for when you are doing a particularly long spraying session to save you aching hands. Wasting water should always be something we mean to avoid, and Spear & Jackson have included a water flow regulator in this garden sprayer for just that purpose.

To prevent premature damage by the user, the pump piston has been given a well lubricated o-ring, and this also helps keep the pumping action smooth and easy. There is also a pressure release valve to stop you accidentally over pumping and damaging the sprayer.

An adjustable shoulder strap has been included to aid you in carrying the weight of the tank around your garden and allowing you to have two hands free.

  • Low price but good quality plastics
  • Well marked bottle for measuring and mixing
  • 1300mm hose and 560mm wand with adjustable spray
  • Easy pumping action thanks to the O-ring that also prevents wear and damage
  • Lockable trigger for prolonged spraying and water flow regulator
  • Shoulder Strap to aid in mobility
  • Pressure release valve will prevent accidental damage

I was straight on the back foot with the Garden Sprayer 5 litre Pressure Sprayer Pump Action. Why? The worst possible thing happened and bear in mind I am an experienced user. I started undoing the pump to drop in some weed killer (I would add pet friendly weed killer as I was treating my front garden) and as I undid it, I thought, that’s weird why did they seal the lid with a bit of grease or silicone lubricant. Yep you guess it, I actually undid the pump mechanism itself! Here’s a look at that:

Garden Sprayer 5 litre Pressure Sprayer Pump Action by Ansio – super annoyingly the pump seal is less tight than the seal with the pressure pot so I started filling the wrong void 😀

No sooner had I begun to pour in weed killer pre mixed and diluted with water than I realised what was going on. I got that hollow sound you get when a container nears full. So that got me worked up off the bat. I don’t know if I am getting more cynical as I get older, or when other products function as they should I become way more critical. I would highlight this is not a mistake I have been able to make with it’s direct competitor, the Spear and Jackson in two years of use!!

So with the only real genuine negative out the way I experienced from testing, I am going to say there are some parts I actually preferred to the Ansio, and I would definitely say over the Hozelock garden sprayer which is also a nice bit of kit. Firstly the distribution rod / hose is decent quality. Your nozzle adjuster is what looks like brass with a stainless steel rod. This is a big step up from the plastic of the Spear and Jackson:

Ansio garden sprayer uses a high quality brass connection to avoid leaks

There’s a problem with this though. Look at the picture and you see all the other components are plastic 🤔. You know that tells me the only purpose is to reduce leaks. You can’t connect a high quality brass to a cheaper plastic fitting and call the product higher quality surely? There’s definitely some contradiction going on there – please feel free to message in if there’s any logic behind that (@manufacturer).

In terms of use the pump pressure was very good. I bold that because without question it’s the most important part of these sprayers, and was equally up to the pressure of my top pick. Where this sprayer definitely wins over the competitors is the sizing. You can get 8L and 11L with exactly the same decent pressure. Fully pumped hard I would say genuinely I was pushing out over a litre, maybe a litre and a half of liquid from one full compression. That is better than, if not equal to all the other garden sprayers I’ve tested, or ever tested in my life for that matter. And if you look closely at the picture above you can see the trigger has a little section where it can slide forward, this will leave the sprayer on so no need to hold down. Very handy – however I would caution it was a bit sticky pushing it back – not a big deal for the comfort of use, especially when I was spraying up large areas of weeds. The pressure release valve is identical to the Hozelock and the Speak and Jackson so no issues there and works just fine.

The strap is nothing fancy. It works just fine but for me at 5 foot 10, it was too short to sling over my neck though, it could only hang from my shoulder – which was fine with a 5 litre pot. If you’re using the 11 Litre version this becomes a problem as carrying that much weight isn’t comfortable and I can imagine it trying to slip down. This isn’t just a criticism of Ansio though, the same issue was found with the Spear and Jackson.

The Ansio garden sprayer strap was too short to throw over my shoulder like a courier bag

If I was going to be doing the kind of work that required lugging 11 Litres about repetitively (to the point filling 5 Litres frequently would be too arduous), I might consider the Faithfull Pressure Sprayer Knapsack 16L however at the pricing, this makes for a far far better deal when you weigh that conundrum up.

Overall I was happy with the quality, definitely happy with the spray pressure and adjustment, but I’d have to stick with Spear and Jackson on price point at the moment. In fact that’s it right there, I’ve said it. Whichever one of the top two picks is the cheapest, would be what would sway my purchase. Both work great and have proven to do loads of work without failing.

3. Hozelock Multi Purpose Pressure Sprayer 5 Litre

The Hozelock multipurpose pressure sprayer is another best-selling product on amazon, but is a fair bit more expensive than the Spear & Jackson model above, and is priced at around 27 pounds at the moment, which is a saving of 54% off the recommended retail price.

So what do you get for the extra money?

Well, overall the quality is just better. The materials used for example, are stronger and more robust than cheaper models, especially the main bottle and pump handle. Even the lance, if a little on the short side, feels stronger and more durable. I would recommend buying a telescopic lance from Hozelock for 10 quid extra to give you better reach unless you’re only thinking of spraying at waist to shoulder height. A problem with a lot of garden sprayer tanks is that there is always some liquid left in the bottom that you can’t use, but Hozelock have managed to design this model so that you get every blast drop out of it.

Hozelock Multi Purpose Pressure Sprayer

As mentioned, the pump handle is large and heavy duty, and also smooth in operation. About 20 pumps is enough to give you very good spraying pressure for a fair while and there’s an integrated pressure release nozzle for safety. A nice feature is that this garden sprayer has a separate filling space so you don’t need to unscrew the pump handle. The tank is translucent and is graduated to help with the correct levels. An integrated dosing cap also helps with getting your mixes right.
 Instructions are printed on the tank, and a holder for the hose and wand are also part of the design, as well as a shoulder harness.

  • Very good quality. Strong and robust
  • Wide base for stability when filling and pumping
  • Designed so you can use every last drop of fluid in the tank
  • Separate filling hole, no need to unscrew the pump handle.
  • Large and heavy duty pump handle for easy operation
  • Shoulder harness included
  • Space on tank for storing wand

If you have a large garden and need something that will keep you spraying for a long time, then this knapsack garden sprayer from Faithfull might the right tool for you. First of all, it has a large 16 litre capacity tank so you won’t have to stop to refill unless you your garden is enormous when compared to my favoured Spear and Jackson as well as being a backpack! Here’s a look at that:

Faithfull SPRAY16AV Pressure Sprayer Knapsack 16L – backpack sprayer

Another handy feature is the fact that you can use the hand pump to pressurise this garden sprayer on the go without having to take the backpack off. This keeps things moving fluidly and really is a time and energy saver. The tank has a good sized filling mouth with a removable filter.

The tank and other parts aren’t made out of the same quality plastic as the Hozelock, but if you spend a few minutes before you use this sprayer to screw everything tight and check the components, you won’t get any leaks. With a 140cm hose and 90cm spray wand, you get plenty of range and reach, and the spray nozzle can be adjusted between 4 settings. There are also spare nozzle heads included in the pack.

The shoulder harness supplied with this 16 litre sprayer is ok, certainly better than our two previous reviews but because of the extra weight when the large tank is full, I’d recommend buying a better one with nice padding. This garden sprayer is available for under 30 pounds at the moment.

  • Large 16 litre tank means you don’t have to stop to refill
  • Keep this sprayer pressurized on the go, no need to take off the backpack
  • 140cm hose and 90cm wand
  • Spare nozzles including a double headed nozzle
  • 4 spray settings
  • Double shoulder harness included
  • Large filling mouth with removable filter

On sale for a penny under ten pounds is this garden pressure sprayer from Garden Gear. It has a five litre translucent tank with markers for you to see the level of the liquids inside, and can be used with any soluble fluids. 
The plastic construction is of a decent quality for the low price, especially the large d-shaped pump handle which feels particularly robust and easy to use.
The tank has a safety valve for releasing excess pressure and preventing damage which is fairly standard these days.

A 170cm hose is attached to wand that has a thick and comfortable handle with a lockable trigger. The hose nozzle is fully adjustable and gives you a selection of spray patterns to choose from. At only 655 grams, this is a lightweight product but of course it will get heavier once completely filled with liquid and that’s where the free shoulder strap comes in. This product comes with a 12 month guarantee.

  • Good quality for under 10 pounds
  • Large and robust pump handle is easy to use
  • Pressure release valve
  • 170cm hose and Spray lance has a comfortable handle
  • Lockable spray trigger
  • Fully adjustable spray nozzle
  • 1 year guarantee
  • Shoulder strap

A 2 litre garden sprayer is a good size for lighter gardening tasks such as spraying the underside of leaves or for use indoors. Their smaller size and weight means that they can be used in one hand and can be stored under the sink or anywhere else for that matter. This compact sprayer from Ansio does everything the larger models do. You can still use it to water, fertilize, spray pesticides, and fungicides. It still works on a pressure system that you need to pump up before use, and it still has an adjustable spray nozzle and pressure release valve, just like the others.

The difference is, this 2L garden sprayer doesn’t have a long hose or spray lance so it is best suited for smaller spraying jobs. It also doesn’t produce as much pressure as larger models, but that is a good thing if you are spraying indoors as it gives you more control and you won’t accidentally damage your plants and flowers.
 As we said, this is a lightweight garden sprayer that can be comfortable held and used in one hand. The large ergonomic handle and thumb trigger give you a good grip and operating position that feels natural.
 The plastics used in this tool’s construction are high quality and it comes with a 2 year warranty.

  • Compact and lightweight and perfect for indoor use or light garden work
  • Ergonomic handle is comfortable to hold
  • Good quality plastic construction
  • Pressure release valve for safety
  • Can be used comfortably in one hand
  • Easy to store away

6. Solo 5L 45psi Piston Pump Manual Pressure Sprayers with Spray Lance

This 5 litre garden pressure sprayer from makers Solo has been designed with a 3 bar operating pressure to keep you spraying for longer between pumping stops.
 The 270 cubic cm pump has a strong handle and a smooth action and doesn’t take long to get to full pressure. Once fully pressurized, the sprayer will be able to operate until the 5 litre tank is almost empty. There is a space on the handle to securely store the spray wand when you are not using it

A ribbed handle on the 50cm spray lance keeps your grip secure and two spray nozzles are included with the sprayer, a flat jet and a hollow cone. You can quickly stop the nozzles spraying by simply twisting them which is handy.
 The transparent tank is made from UV proof polyethylene so it’s durable and doesn’t leak, and it also has a good sized filling aperture that can be used for cleaning the tank out.

This is a good quality garden sprayer, made in Germany and has Viton seals, ensuring a leak free gardening experience.
 This garden sprayer’s dimensions are 19 x 19 x 50 cm and it weighs 1.5 Kg. There is a shoulder strap included to help handle the weight.

Why a garden sprayer over an electric sprayer?

Versatility and mobility are two words that come to mind when I think of garden sprayers – you heard me mention in the intro how I prefer a garden sprayer over an electric sprayer:
 they are versatile because they are able to help you distribute water, fertiliser, fungicides, pesticides, wood preservers, stains, teak oil, and paint, onto the parts of the garden that need them most with minimal waste. I even used my garden sprayer to seal in the tiles in my bathroom I just renovated – you could easily do the same with a patio sealer and brush for ease too.

Most quality garden sprayers make things easy with a shoulder strap, decent pump compression for even high pressure, and have measurement markings on them to make sure that you use the correct amount of the chemicals and a variable nozzle from a squirt to fine spray also helps prevent you using too much – though I caution against a mist with fungicides without proper PPE for pesticides. I think of mobility when I think of garden sprayers as you don’t need to connect them to a mains water supply like a tap when you are using them. You simply fill the tank to the desired level and then either carry them in your hand, or on your back with the help of a harness, or pull them around on wheels. The most common design is the compression garden sprayer, where you activate the pump handle on top of the sprayer to build pressure and then use the hose and spray nozzle until the pressure needs to be topped up again.

  1. HI there,
    In the aim to reduce purchasing a new tool for every single task, I wondered if its possible to use an existing Cuprinol hand pump fence sprayer I already own, which has a 4L capacity, with patio cleaning solution? It frequently got clogged when using diluted paint, but I presume that would not be a problem with a patio cleaning solution (which I’m less keen to get on my hands). Although it does not have a pressure release valve, and I don’t know if the spray is adjustable.
    I have 220m2 of patios and paths to clean, and I wondered if the larger capacity ones spray quicker, or if its purely for the convenience of less refilling?
    I know its best practise to use anything poisonous in a separate watering can/sprayer, so do you have a different sprayer for fertilisers to weedkillers? Or do you give it a really good rinse?

    • Hi Anika,

      I often use my Spear and Jackson sprayer with creocote, wood preserver, and weed killer. I just clean it out between uses thoroughly. It’s way more effective in terms of delivery speed than other sprayers I’ve used. So far, no issues with the above, but I haven’t used it on patio cleaning solution after said chemicals. Sorry I can’t be of more help.


  2. If you plan on using patio cleaner with solvents in, such as sealer, then make sure you get a sprayer with viton seals, normal seals will not last long with chemicals like that.

    • Hi George,

      Interesting point. I have to say this hasn’t been my experience with perished seals. Though generally I give my garden sprayers a good clean out after use. I have experienced perished rubber on fuel lines of petrol strimmers and lawn mowers that have been left for a year or two though.


  3. Hi Terry. I have just purchased the Spear and Jackson garden sprayer and Cuprinol complete wood treatment after reading your recommendation’s. My shed is about 25 years old and of the tongue and groove variety. I have replaced some panels over time and now its time for some TLC. After reading the Cuprinol instructions it recommends painting after treatment. I have used ducks back in the past and thought it quite good. Do you think i can use the garden sprayer with the Ducks back as it would be far easier to complete the job with a sprayer as it is quite tight around the back of my shed. Regards Rob.

    • Hi Robert,

      Yeah painting after treatment is ok to seal in. There’s absolutely no chance of getting DucksBack through a sprayer unless you really water it down to the point you make a mess. If the area was hidden and you were concerned with protection only, I would look to creosote. If there’s an element of aesthetics to this, then get yourself a block brush with a pole for extension, or better, search for a reach around brush, if you are struggling to get in behind the shed.


  4. One thing I have proved is that the Spear & Jackson spray gun are useless for home made vinegar, salt and washing up liquid weed killer. The O-rings and Seals used on all the Spear and Jackson spray guns can only tolerate a Ph level of 9 max. I have mixed a total of 10 Litters and it was good bye seals all melted away. I have spoken to the technical people at Spear & Jackson and they have told me the seals will not work with vinegar.

    • Hi Brian,

      Thanks for the info – I will test this myself and confirm – assuming I get the same result I will update the result accordingly. If you’d be kind enough to let me know what ratios you used so I can replicate your setup. And also let me know how long you left your mix in for too please?
