Richard , same problem when you turn off the pump it also turns off the toilet you have the needed pressure to flush with city water 40-45psi this according to headhunter but the toilet is wired with the pump. I am going to Liberty in Stuart to see if they can wire the toilet with its own switch. Then when on the road or dry camping use the pump when at campsite with correct water pressure you do not have to run the pump. This is a problem I believe that should be fixed by Liberty, but I know I will pay, should not have been wired that way I don't think!
