I would guess the water heater was not quite entirely full or at least had a larger air pocket than typical, making it act as an accumulator. If you have the bypass valves set up in a partially bypassed, partially not bypassed state (which may or may not be possible depending on how the valves are arranged), you can get a far more extreme version of this...which I will say did confound me once for awhile until I saw what I had done.
Last winter, I blew out the water lines to winterize.
This summer, I used only water hook ups.
I never used hot water when traveling/using the pump.
Just went out to the rv and turned on the hot water using the pump only.
Got a lot of air. Turned on other faucet and got more air.
When the air stopped, I tested the pump cycle and the cycle time is back to normal.
So, somewhere in the hot water lines was the "air accumulator".
I'm sure (I think), I opened the hot water faucets to fill the hot water heater last spring.
Thanks for all the responses!!!!!
