Fresh water pump issues

2112 thanks for asking, but problem still there. Have been doing some more testing at each faucet. With shower head on, getting the rapid on off pulse. Took shower head off and no problem. When I put my finger over the opening, restricting the flow, problem returned. Seems that a restriction on any faucet causes the problem. Quite a puzzle. I plan to call Winnebago and see if they have any ideas.

Unless I am mis-understanding what you are saying, it sounds like you've found your problem, a clogged shower head. I know mine needs to be cleaned from time to time due to hard water leaving a deposit. Try replacing the shower head, they are not that expensive. Let us know what it turns out to be.

I had a backflow valve problem on my 2016 Winnebago Sightseer. I contacted Surflow and they are sending me a new backflow valve.

I'm not sure if Surflow can help but they might have an idea or two.

What make/model is your pump?

Yo OP, have you solved this yet? I have 5-1 odds it's an obstructed water line

Do you have a sprayer or faucet in the water compartment, if so make sure both hot and cold knobs are off.

I'm no expert on your particular water system but does it have an accumulator in line. If it looses its air charge it can cause the pump to cycle.

I went around to each faucet. On all, the pump cycles like crazy. Toilet it runs normal. Open low point drain and it runs normal. Took the aerator off the bathroom faucet and it was clean. Without the aeroator, the pump cycled rapidly. Pump had been running normally. Started to make the noise last fall when I was sanitizing the system. I'm fresh out of ideas.

Rapid on/off happens only when water is running.Thanks for the replies.

Open all water faucets, hot, cold, sink, shower, outdoor if you have it, to see if it does it with max flow demand. A low flow demand will cause it to chatter. See if a certain faucet will cause it while others do not. I suspect a pinched/clogged line or fouled flow restrictor.

The line is pressurizing to pump shutoff pressure while you are demanding water. It's not flowing enough water for some reason.

Is this a new coach? Ours acted similarly and after trying a new pump and pressure adjustment the tech found a twist in the hose between the pump and the fresh water tank. He took out the twist so it wasn't kinked anymore and it works perfectly.
