    Blank tank flush

    Is there a black tank flush on the 2017 337rls? If so, where is it? When I run the water pump, it does not shut off and I think I hear a spraying noise. I pulled off the Nautilus plate and can see no water leaking or spraying anywhere.

    There should be two water inputs near your Nautilus panel. The white one is for general water purposes. The black one is for the black tank flush only.

    If your pump is not turning off, make sure you have your valves properly set. You should have it set for "dry camping" when you are using the pump. If you are running off of city water, make sure the pump is turned off. If the pump is still running, try opening all the faucets/shower for a few seconds to bleed any air out of the system.

    Valves are in the correct position. Tried bleeding all faucets in unit. Still spraying noise. I removed the Nautilus face plate and looked inside with a flashlight. There was no sign of water anywhere. Boy, is that space cavernous!

    Michael, did you resolve this? Your original question was about the black tank flush. That does not require a pump. You hook up to the black colored hose fitting which is on the Nautilus panel and use city water pressure to flush while the dump valve is open. Running water pump constantly is another topic.

    Thanks! That did answer my question about the black tank flush. Only had the camper for a week and should have read more of the manuals. I still do have the pump running continually and see no water pouring out anywhere.

    Are you hooked up to a water faucet? If so, the pump needs to be shut off.

    Nope, just topped off tank with water jugs. Sitting in dry camping mode. I can only run pump as needed for fear of water going somewhere else.

    Are the outside shower faucets turned off? If my memory is correct, having them on makes the pump run.

    How about the laundry? Water must be going somewhere. Water heater relief shut?
