The system is "constantly" pressurized from the pump to any faucet as long as the pump switch is on. Causes for the pump to cycle intermittently are:
- There can be some air in the system.
- There might be a leak, say from the "city water" check valve not seating.
- The seals in an older pump might deteriorate.
I had an old pump with worn seals that sounded like a semi's Jake brake when it cycled on. I replaced the whole pump system.
This was my old water pump under the street side bunk:
Water tank to the front (bottom) with the white vent hose, outside wall with "City Water" fitting to the street side (right), water heater to the rear (top), with kitchen and bath beyond... Note:
- The pump is bolted directly to the floor. There is a thin inadequate sheet of rubber under the aluminum base plate.
- The pump output is connected directly to the (gray) plastic water pipe.The regular plastic pipe is NOT flexible enough to isolate vibrations from the pump transmitting to the tank and plastic pipe which transmits to all other fixtures.
- The pump input from the tank is short. While the white hose is "flexible" it is too short to flex.
These 3 items were the cause of most of the noise.
This is the new pump system:
The new "Whisper King" pump is very quiet. I had to re-orient it to fit everything in.
- Flexible hoses loop from the tank to the pump and from the pump to the accumulation tank. They are now long enough to actually "flex" isolating vibrations!
- The pump has a thick isolation mount for each "foot"
- Addition of the accumulation tank also reduces noise
