i have a small problem, if i run the cold water taps shower/sink or kitchen ,
the pump runs perfect, on /off brilliantly, if i run hot water the pump runs erratically, sounds like pulsing,then when i turn hot tap off the pulsing carries on for a further 10/20 seconds, i have tried adjusting the pressure on the small block with a thumb screw on top but no avail, seeing the cold water works on/off perfectly i am at a loss, has anyone any suggestions please. the water heater is a carver with electric or gas heater,on a swift sundance 590 rl. thanks bill.

Mine does almost the same Bill.

I asked the technician at our dealers, and he said they often sound as though they are at death's door, but not to worry as it depends where and how they are mounted.

The run-on with the hot water is just the pump pressurising that part of the system again, and re'filling the hot tank. They all doo it to a greater or lesser degree - mine certainly does.

Don't think you have a problem.

Cheers

I fitted a Fiamma A20 expansion tank to the pump output pipe and it fixed this problem completely. The expansion tank stops all pump pulsing and keeps the water pressure constant. Brilliant device. Don't know why they are not fitted as standard.

Same here for JohnsCross, ordered Monday, delivered yesterday, went to fit it then realised all my fittings are push fit, so it's off to find a couple of 1/2"-12mm fittings from the local plumbers merchant & try again tonight.
