    Vacuflush Troubles- Again

    On my 43 Open, I have a single vacuflush head that has cycled too frequently since I have owned it. So far, I have had replaced some hosing, the duck bills, and at least two pressure switches. Latest cycling symptom--it cycled and shut off every 5 minutes until it finally cycled and refused to shut off--all without the head being used. I am losing no water from the bowl. Any help would be GREATLY appreciated. I am getting to the point where I am going to have the entire system replaced, just to get it work properly. Is it possible that the plastic vaccuum tank may have a leak. If so, why does the darn pump cycle and shut off, and then finally cycle and not shut off--all without the head being disturbed?

    You got a vacuum leak somewhere. They can be lots of fun to find....

    Karl - thanks. What I can't understand is why the switch shuts it down one minute and then it continues to cycle endlessly the next minute. If it's a straight vacuum leak, why wouldn't it be consistent?

    Stick a vacuum gauge on the system.

    The switch may be bad.

    Will do. If it needs to be replaced, it will be the the third one in one year to go. Seems odd to me.

    That is odd; I never had trouble with the vacuum switch - mine was original.

    Then again, you know what they say about everything being cheapened, right?

    Re: Vacuflush Troubles- Again

    I spoke with the "head mechanic", a Vacuflush dealer in Ohio and he believes that since the darn thing is holding vacuum, he believes that the problem is necessarily above the level of the vacuum gauge (i.e the base assembly on which the bowl sits). As soon as my local mechanic can get to it, I suspect that I may be replacing the base assembly (reputed to be an easy job). Given the annoyance that this has generated, I mights as well opt for just going over the side. By the way, price of the base assembly is about $250 while the whole toilet assembly is about $700.

    Well there's a leak SOMEWHERE.

    I'll tell 'ya what - I had that system on my 45C and other than one pump problem I had ZERO trouble with it.

    Sure enough. I hope to have it rectified this week and I will report back. Thanks.

    VF are real simple and very reliable...

    if you have a vac leak big enough to make the pump stay on or cycle on and off every few minutes, you WILL HEAR IT. turn off all noise making things, like air cons, etc.. and listen carefully.

    a bad switch is possible, that's easy to replace... they cost about $120 I think, inlcuidng the electric switch, membrane, rod, etc... 10' job.

    i'd bet on the duck bills... yes you've replaced them but if they are not seated properly they will distord and not hold vacuum.
