SURE SHOT SPRAYERS IN AUSTRALIA
Trouble Shooting Model "B" Sprayers
Normal maintenance includes replacing the B15/B16 valve
The B15/B16 valve will need to be periodically replaced. The Longevity of
each valve depends on the product being sprayed and the amount of sediment
or dirt that gets inside the sprayer while filling.

Four fillings is the average before the valve needs to be replaced. But it is not
uncommon to get more than four fillings out of each valve.
uncommon to get more than four fillings out of each valve.
The standard model B units come with Viton® o-rings, a B15 Viton® Valve, and B12 Viton® valve core. Not all products are compatible with Viton®
There are a variety of o-rings available ((Viton®, Neoprene, Buna & Ethylene Propylene). There are three different valves (B15 Viton®, B15N Neoprene & B16-Buna). There are two different valve cores (B12 - Viton® & B12N - Nitrile). There is a B26 Teflon® air filler assembly when superior chemical resistance is needed.
If the standard Viton® o-rings and seals are not compatible with the product being sprayed please check with the chemical supplier for compatibility with the other o-rings and seals that are available.
Viton® o-rings and seals are standard on Model "B" sprayers because they are compatible with the widest range of sprayable products.
TROUBLE SHOOTING
Problem: Leaks from around B25 valve head.
Reason/Solution
1) B25 valve head to loose: Firmly tighten by hand only.
2) B14 O-ring is crimped or has some loose particles on it: Depressurize sprayer and
remove B25 valve head. Remove valve and check o-ring: Clean away any loose
particles and wet o-ring. Reassemble and repressurize.
Problem: Pin Stream only.
Reason/Solution
1) Liquid is too thick: Thin with proper diluent until sprayable. Consult your chemical
supplier for correct thinning procedures.
2) Too little air pressure: You must have at least 80 psi to spray full contents of
sprayer.
3) Pin Stream nozzle in operating position: Remove. Replace with a spray nozzle.
