Question about Grundfos JPS4 1 HP Pressure Booster Pump

Open Question

Grundfos home booster

I've got a Grundfos Home Booster that until recently has been working fine. It has always provided sufficient pressure to have four outlets running at the same time with good pressure. Now, whilst one outlet runs well as soon as another one is turned on the pressure drops significantly, even though the pump kicks in at the same setting as before. Pump is 6years old. Any idea please???

Definately sounds like a leak in the pipes from the pressure side of the pump onwards, even the smallest leak will cause it to turn on to regain adequate pressure.

it could be the differential in pressure between the cold water from your booster pump and the hot water from your solar water heater . the cold water which feeds your solar heater is probably being reduced in pressure by a pressure reducing valve . so what you need is equal pressure on both your hot and cold water system you could install a pressure reducing valve on the pipe thart feeds your cold taps etc valve set at the same pressure as the one on the solar water heater that would give you a balanced hot and cold water system

You would be better off with a brand that has better representation than Grundfos. Several of our commercial customers change to brands such as Armstrong or Bell & Gossett the first chance they get because Grudfos is less reliable and getting parts or service on them much harder.

SOUNDS LIKE YOU HAVE A LEAK DOWNSTREAM PROBABLY UNDERGROUND. THE PUMP HAS NO REASON TO COME ON EXCEPT TO BUILD THE PRESSURE BACK UP. HOPEFULLY YOU HAVE A GAUGE IN THE DISCHARGE LINE YOU CAN WATCH IT DROP AFTER THE SYSTEM SHUTS OFF. HOPE THIS HELPS, JODY
