Water pump cycling question

On the road now with my 2017 Freedom Elite and have a question regarding my house water pump. Often it cycles on very briefly (half a second or less) at irregular intervals. Obviously my system is losing pressure somehow. Im certain nothing is turned on and haven't found any leaks, wet spots or drips. There must be some sort of a one way or back flow preventer valve at the pump. Do these have any history of failure or weakness? Are they serviceable or replaceable? Thank you for the wisdom of he forum and the willingness to help.

Even an occasional drip now and again will cause this to happen. Maybe your external shower? Toilet? I have never noticed this on mine but then I rarely leave the pump on after I'm done using water.

No more wasted time.

Once system stops pumping after use disconnect input/tank hose from pump. Raise hose end above water level in tank. If water continues to leak out of the pump port - probably bad pump check valve. If you have Kantleak four way valve, problem could be the Kantleak valve. If in wty or close Anderson Brass/Kantleak good about supplying replacement valve and instructions.
