Should I be looking [harder] for a leak?

Our Airstream sits right outside our home on the driveway. We love it there, and are always finding "reasons" to go out for a visit.

So, when the trailer has been sitting with NO water "activity" (no city water hook up, pump turned off, no faucets opened) for three or four days, If I turn the pump ON, the pump will gently run for a second or so... certainly no more than that.

If I do the same test within a day or so, the pump doesn't run at all... it has to sit with no "activity" for a few days before the pump will just go on for a second and right back off.

If I leave the pump ON, there is no cycling... at least not within the time frame I'm willing to leave it on and monitor the situation.

So, my question [finally]: is this super-short "run" normal for a system that's been sitting for a while, or should I be looking harder for a leak. As I suggest, I've looked everywhere I can look in this thing, even used my moisture meter liberally... no indication of a leak.

I my experience, that's pretty normal. Even a small leak will cycle more frequently. You are probably leaking down a bit back through the pump check valve. You have no leak if it goes days between cycling.
