About every 3-4 minutes.
I thought I had a leak somewhere, which wouldnโt surprise me since I replaced the galley sink faucet a few months back. But, not a drop of water anywhere. So, to isolate the problem I installed a shutoff valve in the waterline on the pressure side. Iโd been wanting to do that ever since the original pump failed a few years ago, and was leaking all over the place. Having a a way to isolate the pump would have been helpful. It was helpful now as well.
The new shutoff valve is circled.
With the valve opened, it does this every few minutes. (This is an iCloud link. Just click on the little thumbnail in the lower left. Itโs a 5 second video)
Shutoff Valve Opened
With the valve closed it no longer has all the plumbing in the camper to pressurize, so it cycles much faster.
Shutoff Valve Closed
Thereโs a problem in the pump head, and itโs letting pressure bleed back into the water tank through the suction side. I was hoping it was just a matter of cleaning the diaphragms and valves up, but I pulled the head apart and found this.
I canโt fix that, so I replaced the pump with a new Shurflow pump I had been carrying around since the last failure. The AquaPro is still under warranty, so Iโll try to get it replaced. I hope this isnโt an indication of the quality of the AquaPro pump, because itโs much quieter than the Shurflow.
That Shurflow Shur is noisy. :R

I've stared at that last picture where you disassembled the pump for 5 minutes to see what is wrong but what is wrong?
Sorry, I should have circled that. ๐
The item Iโve circled in the image below I believe is a check-valve that prevents the water in the pressure side of the pump from bleeding back into the suction side. Two of the little plastic legs of the cage supporting the rubber diaphragm are broken, and a bit of the rubber is poking through. With the shutoff valve closed, thereโs very little water line left to hold pressure, so it bleeds down quickly making the pump cycle faster.
