Water pump pulsing issue

[Erik65]

The water pump when turned on from the controller pulses about once every second even when I’m not using any water. The fresh water tank registers as more than 1/3 full. Thoughts?

A place to start. An Escape video about the water pump.

Had the same problem a few days after we picked the trailer up. I had just set up for four days of boondocking and it was about 100 degrees F. The pump overheated and shut down. Turned the pump off and let it cool down and fortunately it re-started. Also fortunately I had watched the bypass valve adjustment video. I did not have the proper size allen wrench but I did have a T-8 torx bit and it worked. The pump manual also describes the adjustment but the video is better. Good luck

Hi jnfroombigt, have you solved the water pump pulse problem? I have exactly same issue now after dewinterizing. I tried to do the adjustment of pressure on pump but it won't work.

We did solve the problem and almost a year has gone by and it has not returned. I did notice that after the pump overheated it became noticeably louder and still is.

Hi Erik65, my water pump has the same problem, just wondering how you fixed it.
Thanks

I was having a similar issue and it took a while to figure out. In my case, a small leak developed in behind the toilet, almost unnoticeable. The leak was just enough to depressure the water line causing the pump to kick in.

Once I found the leak, i pulled the toilet, replaced the faulty part on the toilet, the leak was fixed and no more pump issues... so far.
