water pump runs short burst every 30 mins or so...

sooo, this new-to-me 2014 Escape 21, with everything 'on' (water heater, pump), every half hour or so, the pump runs a very short burst, like less than a second, sounds like a short poot.

Since I couldn't find any trace of a leak or drip, I went ahead and got the kit for the backflow valve, and put it in yesterday. slept in the camper last night to evaluate, and dayum if I didn't hear that PDPDT a couple times. shut off the toilet water supply and bypassed the hot water heater (shutting said heater off), and didn't hear it again.... a few hours later, I turned the toilet back on, and I don't think I heard it again, so that suggests it has to do with the water heater.

I *just* replaced the anode rod, after thoroughly flushing the heater out with the plastic wand made for that purpose, and I'm quite sure I used plenty of teflon tape on it, so I doubt its dripping there (it was POOT'ing before I did this, too). Its been raining all night, so I'll have to wait for dry weather to investigate for water heater release valve or whatever leaks.

I use as little tape as I can get away with. Less is more.

I just turn off the pump when not in use.

It sounds like you have an air bubble in the tank that is slowly being absorbed into the water. Maybe you are not real level side to side and it's holding an air pocket? I can see an accumulator tank coming in handy for that too as it would keep the small pressure changes from firing up the pump.

I like Karen's solution, I do not love my pump charged while not in use.

When you fill the hot water tank open the pressure relief valve to bleed off the air. This should help, mine does the same thing.

I did the same with my 17, but the switch is too far from the bathroom for easy nighttime visits (I know, that is really lazy!). I do shut it off when leaving the trailer for any length of time.

No problems with the pump doing short bursts.

I'm not sure removing the air from the water heater will help - if there is no cushioning in the system such as the water heater air or an accumulator, it seems to me even a slight drop in pressure (due to temperature changes, etc) would cause a short burst.

Somewhat related since it did cause a short pump burst - I had a very slight leak under the sink from the hot water connection that only happened when I first fired up the water heater when it was very cold out. The expansion in the tank, plus the addition of a anti back flow valve on the water heater to protect the pump caused excess pressure on the sink hot water line & a few drips.

Rease suggested using a wrench to get a bit more "turn" on the fitting (it is designed to be hand tightened) & it solved the problem.

Jon not a expert on electrical here but can't another line be run to turn pump on and off ? PT
