correctly
correctly
Electrical
Inlet/outlet connections
incorrect
no water
System pressure has not
pump
no water
Blocked filters
Anti vibration couplers
restricting flow
Air in pipework
Vessel not reached full water
capacity
Leak in system
Air in pump/pipework
Pump vibrating
Anti-vibration couplers/
pipework causing vibration
Connections are not tight
Unit has suffered chemical
damage
not sure
no water
Recommended solution
Check all valves are fully open
Ensure all filters are free from debris
Check pressure of incoming mains. If below 2 Bar/200 kPa consider a
pumped version. Contact PumpWise for more information
Check pressure of incoming mains and adjust pressure reducing valve
if necessary
Check incoming mains pressure and adjust air precharge if necessary
Contact PumpWise on 0191 516 2002
Check power supply
Check fuse
Check circuit breaker and RCD
Check that connections are plumbed the correct way round and all
valves are open
Ensure all filters are free from debris
Check natural incoming mains flow rate (min of 2 L/min required)
Check all pipework valves and anti vibration hose isolators are fully
open
Fully open an outlet to allow pressure to drop within the system
see above
Ensure all filters are free from debris
Ensure that anti-vibration couplers are straight and not bent or
distorted
Ensure isolation valves on anti-vibration hoses are fully open
Open each outlet in turn until all air has been removed
Allow sufficient time for vessel to reach full capacity (this can vary
between 5-40 mins depending on vessel size)
Check all outlets are closed
Check all pipework and outlets for leaks
Open each outlet in turn until all air has been removed
Check rubber feet are fitted to pump
Ensure that the anti-vibration couplers are straight and not bent or
distorted
Check all pipework is clipped securely
Make sure all connections are tight and washers are fitted
Ensure that no part of the unit has not come into contact with
chemical substances such as solder flux
Check leak is not from pipework above or around the unit
See above
