Water Pump question

Apologies, as I'm sure this has been asked before but my search didn't turn it up.

My water pump kicks on for about half a second every (seems like) 5 minutes or so. I don't notice any leaks at all, and I know it is supposed to do this somewhat to maintain system pressure.

Is this excessive? I'm not too worried, it's not like it's kicking on for seconds at a time. It does seem like a "top off".

Thoughts?

Thank you in advance!

There has to be a leak to the outside world somewhere or the pump itself is leaking back. It should go for days without ever coming on.

Mine hardly ever cycles. Sometimes I'll go hours after we get to wherever we're going and forget it's even on. It lets me know when I turn on a faucet while we're hooked up to city water and it tries to re-pressurize the system.

Could it be air in the system somewhere? Air doesn't compress like water and could cause cycling like that? Just a thought ...

Another possiblility- Whenever you turn off the water heater, the air cushion contracts when it cools, and the pump will cycle to maintain pressure.

Did you check for leaks in the fittings near and on the water heater itself? I had leaks at the fittings going directly into the water heater, and had quite a wet situation before I found it. Would've found it much earlier if I hadn't been on city water, and was using the pump instead.

Exact issue a couple weeks back, bathroom sink had a Sloooow drip. I'd start with all faucets and see if that doesn't fix it.

Check toilet to see if the valve is leaking or the outside shower for leaks and also that the valves are fully closed.

pump

Well this is all very interesting. I'm glad I asked, thank you. We've been at the CG for 36 hours now and no leaks anywhere. No faucet drips, toilet fine. Water pump looks great, no leaks. Water pressure is great, no weird noises.

Water heater looks good, no leaks. The water heater air thing, I can't say although I have had it off to conserve propane. We're dry camping.

Should the water heater just always be left on?

And this is a brand new TT.

Thanks all for the help!

I should say since I read that water heater air comment, I've had the heater on for 45 minutes and I haven't noticed the cycle, but I haven't tuned in to it either. I'm watching now.

it just cycled. It does seem to be less frequent with the heater on. That could just be a perception though

Sorry one more thing. I have had the A/C running and there's water coming off the left front of the roof....I'm assuming that's condensation. I just thought I'd mention that however.
