Hi Guys,
I've got a developer-supplied water pressure system modeled Grundfos CM-PT installed on a 3-storey link house. Just moved in, it was working fine for a month, and now the pump runs continuously without stopping. Sometimes the low rumbling sound also accompanied by groaning sound. There's a switch that I used to turned it on 24/7, but now due to the incessant sounds from the pump, I had to turn it off whenever water is not used.
Is it normal for a water pump to run continuously...? Previously it only runs intermittently when water is used especially on top floors.

QUOTE(enriquelee @ Sep 25 2017, 10:43 AM) Some times it is cause by other simple factors such as tap is not properly turn off, wc flush spoil and etc. Check all these simple things 1st before further investigate which might cause a lot of hassle. You were right... Found the problem... Someone itchy-handed and switched the toggle of my water filter to "Stop" position. I ended up draining my entire water tank...  |

Pump running even using only small amount of water which previously only after open a few tap only the pump will run. Any idea? Get a water pump technician to check if the cut-off switch is faulty... |
