Fault Probable cause Recommended solution
Reduced/
intermittent flow
Incorrect or no
anti-aeration flange fitted
Check that installation complies with Salamander instructions
Insufficient gravity flow See above
Blocked inlet filters Ensure that all filters and shower head are free from debris
Couplers restricting flow Ensure that all AV couplers are straight and not bent or distorted
Air in system Run system on full hot with pump switched off (i.e. gravity only)
for several minutes
Check cold water storage is correct for installation and pump is
fitted to Salamander instructions
Ensure cold water refill rate is adequate for installation
Check that vents are fitted as described in instructions
Wrong size pump for
system
Ensure pump is sufficient to run the equipment
Hot temp set too high Reduce cylinder stat setting to 60ºC max or fit HWS/TMV
Pump starts with
all outlets closed
Leak in system Check for leaks
Outlet open Ensure all outlets are fully closed or capped – i.e. no dead legs
in pipework
Pump is noisy Air in system See above
Pump vibrating on surface Ensure rubber feet are fitted to pump
AV couplers causing
vibration
Ensure that all AV couplers are straight and not bent or distorted
Pump is leaking Pump exposed to mains
water pressure
Check that installation complies with Salamander instructions
Pump has suffered
chemical damage
Ensure that the pump has not come into contact with chemical
substance i.e. solder flux
Pump exposed to
excessive temperature
Is effective temp control fitted (cylinder stat or HWS/TMV valve)?
Pump appears to have
leaked but not sure
Check leak is not from fitting in pipework above pump
