Water pump turn on/off problem
Roadtrek 170. I'm having a problem where the water pump turns itself on in the middle of the night, and will turn off only after I bleed air from the system by turning on the sink faucet for about 10 seconds. (When I remember, I switch off the pump to avoid the nighttime fuss.) The faucet sputters for several seconds, eventually the water pressure builds and the faucet and pump work properly (ie the pump again turns off when the faucet turns off).
Anyone have experience with this problem? I've checked the hose clamps on the plumbing accessible from inside the van, see no obvious problems. There are no leaks on the inside, but I'm not sure about the underside.
Thanks in advance, Jim
