Sprayers – Frequently Asked Questions
Q. I have lost the nozzle cap from my sprayer. Can I purchase a new one?
A. Yes. These can be purchased from some Garden Centres or Customer Services.
Q. My sprayer is losing pressure.
A. This could be due to a split non-return valve located at the base of the pump mechanism or perished washers and seals. A replacement seal kit is available from Customer Services.
A It’s important to distinguish between losing pressure and not achieving pressure. First check is to remove the pump and place the bottom of the pump against the flat palm of the hand (wearing rubber gloves if a chemical is present). Pumping the pump should result in pressure being felt coming out of the black non return valve of the pump. If this is so then the bottle is probably getting pressure but subsequently losing it. If no pressure is felt then the sprayer isn’t getting pressure in the first place so the most probable cause is a faulty/missing/dry plunger O ring or leaking non return valve. Replace or lubricate as necessary
Q. Can I use my sprayer for shed/fence treatments?
A. The sprayers have been designed to apply water based garden chemicals and are not generally suitable for applying shed/fence treatments. The Multi 5L (4455) sprayer and all those in the Viton range are equipped with special seals, which allows them to spray a wider range of treatments. Considerable care needs to be taken though, to ensure that the intended treatment is suitable for use with sprayers and that the sprayer is thoroughly cleaned after use.
Q. My handle has split. Can it be replaced?
A. Yes. The different handle sytles can usually be accomodated by the latest design These can be purchased from Customer Services.
Q. My sprayer will not stop spraying when the trigger is released.
A. The most likely cause is grit or dirt in the on/off control. In which case dismantle the on/off control, clean thoroughly and replace. If the spray fails to shut immediately and continues to dribble out it could be due to air being trapped in the lance. To remove any air, hold the lance in a vertical position pointing away from you, toggle the trigger on and off until the air is discharged, then continue spraying.
Q. Where can I buy spare parts?
A. From some Garden Centres & Customer Services.
Q. Where can I buy a new sprayer?
A. From Garden Centres, DIY multiples & stockists of our products.
Q. Can I purchase a replacement bottle for my sprayer?
A. No. They are not available.
Q. What about brass nozzles and leather washers – are these still available?
A. No. They have been discontinued.
Q. There is a leak on my sprayer somewhere but I cannot find out where it is.
A. A simple way is to fill the sprayer approx ¼ full with clean water. (make sure there is no residual chemical in the sprayer and wear rubber gloves and safety spectacles). Pump the sprayer to pressureize it and then tip it upside down and observe for leaks. All the seals on the bottle will now be covered with water not air and so leaks will be clearly seen as water dripping. Replace seals or tighten components as necessary.
Q Why do the seals on my sprayer need replacing so often?
A. This can be due to many things. Here are a few examples.
1. The sprayer is left pressurized – ensure pressure is vented by pulling the pressure release valve after use
2. Chemical is left in the sprayer – clean any chemical after use and flush through with clean water.
3. The chemical used is corrosive. – only use branded garden chemicals suitable for treating garden pests or problems. Don’t use the sprayer as a spray gun for spraying paint thinners or any other chemical. Definitely don’t use anything containing white sprit as this will cause the bottle to age harden and possibly break.
4. The sprayer has been left in the sun – this can cause the seals to dry out so ensure sprayer is put away after use and not left in direct sunlight.
5. The seals are not lubricated. – Moving seals such as the piston in the pump and the o rings in the tap need regular lubrication as any chemical used may dry the seal out over time. Remove the necessary parts and lubricate with either silicon grease or Vaseline.
Q. I only need the non-return valve for my sprayer are these available?
A. Yes from Customer Services.
Q. The container of my sprayer has split. Can it be repaired?
A. No. Not only is this highly dangerous, the pressure in the bottle when pressurized is too great for any adhesive to seal it effectively. Do not take chances. Renew the sprayer.
Q. Your lances used to be made out of aluminium but lately they seem to be made of plastic. I’m not sure they will last as long. Can you reassure me?
A.. The plastic used in the lances is a high-grade resin, is more resistant to bending and kinking than the aluminium and will last at least as long.
Q. What chemicals can I use in your sprayers
A. This is a far reaching question as it’s not only the suitability of the sprayer that needs to be considered but also the suitability of the chemical when being sprayed. Volatile chemicals can be very dangerous when sprayed and care needs to be taken whatever chemical is being used. Normally any propriety substance for garden use can be used. If in doubt the best course of action is to contact the supplier of the chemical and ask if it’s suitable for spraying using a pressurized sprayer. do not use the substance. of course always wear protcetive goggles gloves and a mask when spraying.
Its also important when mixing chemicals to make sure they are mixed correctly. Some chemicals can be mixed with water but the chemical might need adding to the water and not the other way round so check the instrcutions.
