Black tank overflow !!!

Tank level indicators were all showing crazy amounts. Drained and flushed tank with built in rinser. Closed valve and let rinser wash out and fill tank. Drained.. Did this several times until water was running pure. One more time for good measure...;)
I got distracted setting up the Grandkids fishing poles and next thing I know I had water coming out of the vent pipe. It was clear but I had some water on the floor around the toilet. Opened valve but without the air vent it would not drain. Flushed toilet and it exploded in my face.:o Cleaned up water while tank drained.
Question is...did I do any damage to anything by letting the tank overfill and flow out the air vent?
Sad thing is..tank level indicator still not correct!
  • Well I guess with water running out the top of the vent you could say you don't have any Black tank leaks. I sure wouldn't have guessed that no water would have flowed out with the vent full of water. I would have thought that the added pressure would have pushed the water out the drain.

    Same here. I do it just before getting ready to leave. I stand right beside the pull handle and where I can see the clear extension. After fully drained and flush on, I close the black tank valve no longer than a couple of minutes then open it. Do that until the water comes out relatively clean, about 4-5 times. Lots of extra "stuff" comes out the first time or two.

  • I use my built in black tank rinser once a year at the end of the camping season and I leave the valve open as I use it.

    And this is a prime example of why I don't "flush" my tank. I've seen this happen way too many times on here. I just don't need a chocolate river flowing through or over my RV.

    When I look down the bomb bay door and see the offending items close to the bomb bay door opening I know it's time to dump the dumper. :B


    X2! I was also thinking OCD.

  • I've done a very similar thing. Just be thankful it was after several rinse cycles. Just make sure any wet spots are cleaned up and allowed to dry.
  • My children borrowed my MH for a fun week last year. Daughter called me to check the hookups, and said there was no water pressure in sink.???? While talking about it she screamed the toilet was overflowing!!!! Yup, she hooked the water up to the black flush line. No damage other than to her pride. They still borrow the MH regularly.
    Happy Trails.

    Wipe your face off and go camping :)

    Probably didn't damage anything assuming there is no water damage to the floor.
    I wouldn't worry about it.
