Pump Inlet & Discharge Valves Facts:
Both inlet and discharge valves in all of our pumps with one exception are the same and can be installed in any port. The exception is the XJV & SJV series pumps where the inlet valves have high tower cages.
Valves are wear parts and need to be changed when they become worn.
Life of the valves depends on several factors – water hardness, water cleanliness, dirt filtration, cavitation or if chemicals are run through the pump.
Trouble shooting potential valve problems:
Pressure gauge fluctuates or there is a pulsation in the inlet or discharge line – The valves are probably worn and should be replaced
Low pressure – worn valves, debris stuck in the valve(s), accumulation of dirt or hard water minerals in the valve(s), the valve poppet(s) are stuck to the valve seat(s) from the minerals in the water that has evaporated after long storage periods. The valves should be cleaned or replaced.
