When 1st using faucet decent pressure for a couple seconds then pump runs for 10 seconds or so and pressure is normal, next day same thing. Can find no leaks,,, help please
Look at your one way valve that is supposed to be able to hole the pressure when the pump stops, it is located directly on the pump. Google your pump and take a look.
On my rig, there are neoprene washers in each hand tightened pipe joint. One washer was pinched and leaking just enough air into the line that it wouldn't pump water. Real pain for a 20 cent part.
