ok, detective work it is thanks everyone :)
Also check the pressure relief valve of the water heater. Ours will "weep' and the pump will kick in for a split second every 1/2 hour to offset the small water loss.
Yup. I used to experience the same thing - on the current and 4 previous RVs.
I have found that over time, the air gap in the hit water heater is taken up by water. The smaller the air gap is, the higher occurrence of the pump "blip".
When heat cycles occur, water expands slightly... Air compresses, water does not.
Part of my "arrive at the campsite setup routine" now includes opening the HWH relief valve (pump off of course) until no water flows out... Snap it shut.
The blip almost never occurs any more.
