    Toilet malfunction...

    1999 27' sundancer, toilet is a Sealand, model # 848, power vacuum flush when you step on the 'foot-pedal, and refills with water when you lift the foot pedal. Problem: the rounded 'half moon' that falls back into place after each flush does not fall back into place, also, no pressure... Any ideas? Thanks

    You could try to lubricate the ball and gasket pouring some vaseline oil into the bowl. It has been working for me for some 20 years and I never changed the gasket.

    Re: Toilet malfunction...

    Pietro is doing what alot of people on CSR are doing. Can not tell you one way or another on the Vaseline. It sounds like either your ball valve has some deposits on it ex.. calcium or lime deposits? Also your seal may be dirty and in need of just a good cleaning. The last posibility is the Return spring on your foot petal is wore out and just not able to close correctly. Try and pull up on the ball and see if it will seat and let your vacuflush produce vacume and shut off then you can narrow down the possibilities. Try what is stated and if not give out another shout and we can come up with something else. Also i have always had great luck dealing with Dometic with Questions and help. Let us know if this helps.

    One tip I got from the vacuflush dealer is to always let the pedal "snap" back into place, never let it up easy just let it go from the bottom.

    I would also suggest to clean the gasket with regular round toilet brush and then apply a lubricant.

    Also, as a second part you should lift the pedal to add some more water to the bowl.

    Re: toilet malfunction

    there is a spring on the foot pedal, this may be worn, also you may have to change the seat gaskets.Sealand sells a kit that you can purchase to rebuild the seals. It is either the seals under the bowl that are worn or the spring mech that is bad. The ball (half moon) may also be purchased. But I don't think that that is the problem. However you may also call Dometic and they will help you with the problem this page will show you the parts that may need changing http://www.environmentalmarine.com/

    Re: Toilet malfunction...

    All of that is good advice, although I prefer a teflon lubricant, it won't harm seals and costs about the same.

    In the future you only need post in one forum. The users here check "New Posts- 24 Hours", that way we see all new posts at once.

    Good luck with your issue, MM

    It would be nice if a moderator could combine the twin threads so all information is in one post. In the future you only need post in one forum. The users here check "New Posts- 24 Hours", that way we see all new posts at once.

    Good luck with your issue, MM
