Water pump on intermittently?

The water pump will prime and then can be heard recharging the line for a second or two every few hours. So I opened every panel and drawer checking every joint and connection I could reach. No leaks and nothing loose. Starting my third week of camping with our new TT.

What's up with that? Is this normal?

I had the same issue and finally felt each connection on the pump and found one with moisture on it. A very, very small leak that took a while to cause the pump to activate.

You have a leak somewhere, may take time to find but eventually you'll find it.

We developed a leak, initially the pump would run occasionally, every 3-4 hours but got progressively worse. Eventually I found standing water in the same compartment as the water heater and narrowed it down to the leak. Waited till we got home and removed the water heater and found a pin hole leak at a weld seam. Decided to replace instead of repairing. Cost ~$500.

Wait long enough and you'll find the leak. good luck

Had exactly the same experience.

Finally, a few weeks ago, I noticed the pressure relief valve on the hot water tank weeping a little water. I pulled on the valve a couple of times to relieve pressure, and it's been dry ever since. The pump has stopped it's intermittent cycling, so I guess that was the cause of the problem.

Long term, moving to a water pump with a bladder diaphragm tank would be the ultimate answer, but for now .......

On my Rockwood, the toilet flush valve sometimes leaked just a bit. Pressed the foot pedal, let it slam shut, voila! leak fixed.

I'll check that this afternoon, we've had so much rain here I assumed the water I found in the water heater area was rain water.

I think it is not uncommon for some minor "leakage" to occur within a water pump itself, specifically between the output and input sides of the pump. Thus, after checking for water everywhere, I don't worry (much) about our pump hiccupping once in awhile. Also, I rarely connect to "city water" so that if leak should develop in our on-board water system, I would know it. At least until such time as I become completely deaf!

I read about this issue a lot on these forums.
My last trailer did it, took the Shur-flo pump apart and replaced the diaphragm parts.
Solved.

Just joined the forum today looking for this exact topic. I have a 2017 Creekside 20fq and have taken it out twice drycamping. About once every couple of hours I hear the pump kick on momentarily. I guess I will be looking for leaks this weekend. Thanks for the topic.

Could be the pump check valve too.

Leaks are fairly obvious and don't take long to spot. My pump burps a couple of times a night too but there are no leaks so it can only be the check valve in the pump that's allowing a bit of water to pass through. I'm not going to worry about it at this point. Will cross that bridge at a later date if it gets worse.

If you have an ice maker, it could be the ice tray refilling, it only takes a few seconds and could occur every couple of hours or so. Drove us crazy when we first got ours and then realized what it was.

No ice maker on the Black Rock. Although that would be a good answer otherwise.
