Toilet Question

Our 2015 Shadow Cruiser toilet water will only work if the pump is on even if connected to city water. Anyone ever heard of this? Took her out on her maiden voyage over the weekend to figure things out.
  • Do other faucets etc work with city water connected and the pump not on? This is one I have never experienced, but sometimes there is a valve to switch between city water and city water directed only to the fresh water tank. Maybe you have one of those? Just a guess.
  • Somethings wrong in the plumbing somewhere. We've never run across that and I thought we'd seen everything!!!!!!
  • City water and pump discharge connect to same plumbing system (cold water plumbing). Toilet water flows when using pump it ALSO will flow when using city water just like kitchen faucet, bathroom faucet, shower do.

    No separate valve to swap for toilet.

    Some RVs have a 'utility panel' where city water connects and valves/switches have to be changed to use: city water, use pump, fill fresh water tank, winterize etc.
    But other than that panel the plumbing inside RV is same system.

    So what did you try first......pump then city water?? OR city water then pump?
    If pump then city water............did you try pump again?

    Only thing I can think is city water pushed some debris/crud into toilet water valve clogging it.


    Basic RV water plumbing system (regardless of utility panel or not)

  • Strange because as said it is all the same pipe. One pipe goes to the toilet and that should work is the sinks all work.
  • IF toilet flushed using pump and then didn't using city water bet it doesn't using either now cause toilet water valve inlet screen is clogged or valve is clogged
  • Thanks all for the responses. It is going back to dealer tomorrow for a punch list of things to do. Also noticed it will not fill by barely pressing the flush pedal. Debris may be the culprit!
  • Old Biscuit, tried city water first then pump. The very wierd thing is if it didn't trigger the pump when pedal pressed, I could turn on the bathroom sink and then it would flush. Awesome diagram btw!
  • Well, our dealer said the toilet was bad and will be replaced. Didn't say what was wrong but as long as it works, its fine.
