Continuing to be stumped. The cycling time is now down to three seconds! The parts house refuses to consider that the pump might be defective.

Has anyone had any experience with a company named USA Adventure Gear? They have a pump, comparable in price to what I paid for the Shurflo, with a lifetime warranty: this one here.. Says it's compatible - implied bolt-in compatible - with the Shurflo.

Still some more tests to run, but no sunshine on this project yet. Damitol - I've got so many OTHER things I want to do.

To make checking your pump even easier, do you by chance have caps on your low point drains? If so, use one of them on the output of your pump to test it.

The low point drains on our 2004 Tioga 26Q are hard to access and hard to shut off , if not shut off completely, pump will cycle.

That's not what I meant. I meant if his low point drains have threaded caps instead of valves, use one of those caps on the output connection of the pump. Then turn the pump on to see if the pump holds pressure. This will take all the plumbing out of the equation except the pump. If the pump still cycles when it's capped, the pump is bad. If not, the leak is elsewhere.

Internal leakage in the toilet? Is there a shut-off valve on the toilet you could use to isolate it from the rest of the system?
