I've used my tank flush three times. Once with the house hose and no regulator, just opened the faucet about a third of the way. Once at the dump station with a regulator, and once using my outside shower. I think I like using he shower the best. You have the option of using hot water, and you know that the pressure will not exceed the safe operating pressure of the check valve.

I just wish my flush fitting was on the same side of the trailer as the shower.
