My water pump is very noisy and vibrates the pipes down the side of RV. What could be the problem?
If you've ever wakened your RV or camping neighbors with a midnight bathroom break then you can understand how noisy some water pumps can be.
Although it can be a common problem it is usually fixable. Below we've listed some typical issues and how to solve them.
1. Faulty manufacturing and design
Some RV manufacturers scrimp on installation and material costs, compromising the quality of their water pump. Symptoms of faulty installation are loose mounts causing vibrations, clanging pipes and water hammer.

2. Rapid cycling
When a water pump runs rapid cycles on and off, it creates noise and causes vibrations. You need only to adjust the cycle settings to fix this problem. Check if you need to adjust the pump by turning on a faucet to low flow. When the pump cycles and its OFF time is 2 seconds or longer, there is no need for adjustment. But, if the OFF time is faster than that, you need to correct the problem of rapid cycling.
Turn the adjustment screw 1 turn clockwise or until the pump reaches the required 2-second (or longer) OFF time.
3. Additional water storage needed
When the water pump can no longer store water under pressure without causing vibrations, you may want to install an accumulator. Contact your RV supplies dealer and ask for an accumulator that is compatible with your RV water pump. The accumulator tank acts as an additional storage for water. It prevents the pump from rapid cycling and prolongs the life of your RV water pump.
