Quick troubleshooting for RV Plumbing
If the pump cycles on/off:
Check for a small leak at a fitting or toilet valve
Verify the pump strainer isn’t cracked
Check city-water check valve backflow
If you have low pressure:
Confirm you’re using a pressure regulator (and it isn’t restricting too much)
Check for a kinked hose or clogged filter
If on pump, check the pump strainer and air leaks on suction side
