Water Pump cycling

2016 27RLS

As issues I read about on here go, this is not a deal breaker. Nonetheless it has been an ongoing issue, even after 2 (TWO) stays at the dealer to repair it. This being our first trip of the season, I find I still have the problem.

My water pump will cycle for about 1/2 to 1 second every 5 or so minutes. That frequency varies.... with the only variable I can think of being outside temperature.

I have no idea how extensively the dealer sought the cause, but they seemed to be conscientious and had it for a couple of weeks on one stay. I was pretty adamant the 2nd time I had to bring it in, so they had a mandate to get it fixed.

There are no visible leaks anywhere, although we do have the bottom covering. I'm assuming the dealer would have located any leaks. The water pressure is fine when it's running.

I'm assuming (perhaps incorrectly) that the dealer examined everything. Can I get some ideas? Maybe to take back to them this upcoming THIRD time?

Thank you in advance!

You have a leak! Very small but none the less you are getting a pressure drop and that's what causes the pump to run for just a second. It could be one of several valves. Faucets you should see a drip. Could be your toilet valve, that one is tough to see if it's leaking. Your water heater plug and pressure relief valve can also make this happen if they are not sealed tight.

X2!
I have the 2015 27RLS, once the water has fully filled the lines and all the air is out, the pump rarely cycles. Cycling every 5mins IMO is a leak.
Also, do not count on the dealer doing a thorough job, they are more likely to take a quick look and then claim it is fixed.

Other than water leaking, it seems a faulty pump could have an internal leak. Either the pump could be changed or a shutoff valve placed in the pump output line to isolate the problem to either the pump or 'down stream' from the pump.
(BTW, you only know about the leak when using your trailer's pump because the pump cycles. When on 'city' water, if it's not your pump, water is still leaking. )

If you have a leak, it needs to fixed. Over time, water is a TT killer.

Usual they avoid lines in the underbelly unless they have no choice incase there has to be plumbing on both sides of the unit. If there is no insulation in the underbelly those pipes are prone to freezing. You definitely has a very small leak or the backup valve in the pump is leaking. To test that you have to block the pressure side of the pump. I use a 4 ft. Pex pipe capped and installed on the pressure side. You might have to get an extra pump fitting.

The pump can also be leaking back into the tank.. I will bet this is where you are having your problem

When you're looking for the simple solutions first, don't forget your low point drains. Mine have a tendency to leak if they're not seated just right. This could be a cause too.

I agree that water is probably leaking back through the pump. Running some brands of pumps dry, even for a few minutes can damage the pump impelled enough that it can leak.
Some other types of pumps use a check value and that could also be bad.

And check the toilet

If the flush valve isn't completely closing it'll seep and slowly fill the toilet bowl, but if slow enough, folks are flushing it empty now and then. A test is to flush it dry with pump off, then turn on pump and check it after a few hours. If water is pooling you have your answer.
This would also happen on city water and could be a disaster, or an early morning surprise.
