My water pump keeps cycling off and on briefly. Whats the cause?
Most likely a leak in the plumbing or pump. During the first pressurization of the system per the year, you’ll want to check for system leaks. Let the pump run until it has the system pressurized and shuts itself off. It should STAY off, if it cycles periodically or refuses to shut off at all, you probably have a leak. Some trailers have a bypass valve/line that’s mainly used for filling the on-board tank from the city water connection. If this is left open, the pump will never build up any pressure, nor will you have any pressure when the water hose is connected to the city water hookup – everything’s going back to the tank. Look for this and close it if your trailer has one. A cycling pump can also indicate worn seals inside the pump.
