PROBLEM
CAUSE
SOLUTION
System does not
dispense solution
1. Water inlet strainer is clogged
1. Clean it or replace if necessary
2. Too much water pressure
2. Use a water pressure regulator in case of
more than 130 PSI (9 bars) water pressure
3. Insufficient water pressure
3. 15 PSI (1 bar) is the minimum required pres-
sure. If not available, consult a plumber.
4. The venturi is clogged
4. Soak venturi in hot water and inspect visual-
ly, gently removing debris. Replace assembly
if needed.
5. Activation valve is clogged by mineral
5. Soak the valve assembly in a solution of hot
water and limescale remover. Replace assem-
bly if needed.
Water flow won’t stop
1. Activation valve is clogged by minerals or
other waterborne debris
1. Soak the valve parts and valve seat in
limescale remover to clean. Replace them if
necessary.
Activation valve is
leaking
1. Valve cap not tight enough to seat
1. Firmly hand-tighten the valve cap until leak
stops.
2. Not properly positioned
2. Reposition the valve or change it if neces-
sary.
Connections and end cap
are leaking
1. Missing o-ring in the connection fitting and/
or end cap
1. Apply the o-ring or replace the entire part.
2. O-ring in the connections or end cap are
damaged
2. Replace the o-rings or replace the entire
end cap.
F-gap back-flow preventer
is leaking
1. Flexible membrane is damaged
1. Replace the back-flow preventer.
A-gap is spraying out
and/or leaking
1. Limescale film or dirt on the A-gap’s upper
nozzle
1. Soak in hot water and limescale remover to
remove buildup. Replace if necessary.
2. Venturi coated with limescale or dirt
2. Soak in hot water and limescale remover to
clean. Replace if necessary.
3. There is a buildup or clog in the discharge
hose
3. Clean the hose to eliminate restriction.
4. Discharge hose is above the dispenser
4. Make sure the discharge hose dispenses
below the dispenser, insuring no back pres-
sure.
Improper concentration
of chemical or no suction
1. Insufficient water pressure
1. 15 PSI (1 bar) is the minimum working pres-
sure. Check plumbing options.
2. Metering tip clogged
2. Replace tip.
3. Foot valve clogged
3. Soak in hot water. Hand-clean or change it.
4. Venturi or back-flow preventer clogged
4. Soak in hot water or limescale remover to
clean. Replace if necessary.
5. Air leak in chemical pickup tubing line
5. Check the entire line. Replace the tubing
and check the connections and cable tie.
6. Product is too thick
6. Change the pickup hose. Switch to a bigger
diameter (need 1/4 x 5/16” coupler).
7. Product container is too far from the system
7. The standard installation is positioning the
tank under the system (5 ft max).
8. Excess concentration
8. Tip is not the correct one or not fully seated.
Pressure variations can require adjustment
from chart recommendation.
System continues to draw
chemical after the valve
is closed
1. Chemical tank is positioned higher than the
dispenser, causing siphoning
1. Move chemical container below the dis-
penser discharge point.
