Push button toilet flush problem

Discussion in 'Misc DIY' started by Keiron Carroll, Apr 3, 2005.

  1. I have one of the new type push button toilets I installed just last
    year in the bathroom and have noticed in the last month or so that there
    is a continuous trickle of water flowing from the rim into the bowl and
    every now and then including throughout the night a subsequent top-up
    sound heard. There seems very little in there to go wrong, is there a
    diaphragm I wonder at the very seat of the central fixings which could
    possibly be leaking?? I haven't a clue how this new type flush system
    works and would appreciate any help from those more enlightened. It's a
    two button arrangement and has a 'float' connected to these buttons
    indirectly. I have to say it all looks very very flimsy. I'd also
    appreciate any web site url's which show this kind of arrangement so I
    can learn a bit more myself. Many thanks in advance.

    I will be interested in the answer. I have one about 3 years old after
    flushing fills up then overflows for about 15 seconds, not a problem
    just a waste of water. I have taken it apart and can find no obvious
    problem.

    Mine is a single button type but I was never happy with the float
    arrangement due to the slim ciston not actually being big enough for
    the float to float freely so it tends to stick against the mechanism
    or wall.

    The water comes from a plastic tube in the middle of the top bit,
    imagine a Kerplunk type object sat in the top and that's it.
    You push the button and it opens the bottom bit and the water flows
    out so the seal could be leaking.

    Mine's due to the internal overflow doing it's job when the float
    sticks. Still beats it overflowing under the bath like it did before
    I replaced the suite. ;-)

    The problem often arises from a build up of lime scale around the
    discharge pipe from the systern into the toilet. The rubber seal can
    no longer completely close off the pipe.

    A few months ago, there was an inventor on television. He has
    developed a device to solve this problem.

    The device is mechanical. When you flush, the systern fills with
    water. When the systern is full the water stops flowing and it trips
    the device. The unit will not allow any more water to enter the
    systern until the flush handle is depressed. This means that the
    systern will not keep refilling in the middle of the night whilst
    water is leaking out.

    Surprise to say that the inventor said no one was interested in the
    idea. The water companies wanted people to use more water so they
    could charge them for it. The toilet manufacturers were not interested
    as it would amount to an admission that their equipment would
    eventually start to leak.

    The inventor never indicated the likely cost of the unit if it went
    into production. Presumably a repair of the current unit on several
    occasions might work out cheaper in any case?

  5. Odd that it is only comparatively recently that this type of
    valve has been permitted. AIUI the risk of water wastage was the
    reason they were never previously allowed. Looks like they still
    haven't solved the problem.

    I am an amateur but have had experience of this recently. M
    understanding is that instead of a traditional overflow pipe which use
    to exit the cistern towards the top and go to either a soil pipe (o
    directly outside), the new flush valves have an internal overflow wher
    water can trickle through the big hole in the middle top of the flus
    and into the pan.

    The float valve - which does the same job as a ball valve can sometime
    get stuck - especially if you have a slimline cistern. You need to mov
    it up and down by hanbd and check that the wall of the cistern is no
    stopping its free movement. If it is free, you need to adjust thi
    float valve so that it cuts the flow when the water level is around th
    6L mark (It think this is a UK standard). Mine was fixed after muc
    trial and error - but is fixed now because I have since fitted two mor
    - and apart from all the instructions being in italian and looking lik
    the illustrations had been drawn by a 4 year old they both failed.
    I replaced them both with a Fluidmaster float valve - c. £10 from B&
    and have had 18 months free from any trouble. I was also advised tha
    these are both low pressure and high pressure compatible, but main
    pressure was preferable. I have no mains water freed to either, bu
    they work a treat nevertheless

  7. Is it a multikwick (blue and yellow IIRC)? Are you in a hard water area?

    (From your description it sounds more like a flap valve but the one I've
    seen - can't remember the name off the top of my head - doesn't have a
    two part button.)

  8. Not tried the fluidmasters or other flap valves. I agree drop/flap
    valves have a failure mode in which they can let by whereas syphons'
    only failure mode is simply not flushing, so in that respect they're A
    Bad Thing (and presumably why they were resisted by the Powers That Be
    until recently). It's a pity no-one makes conventional syphon valves
    just a bit shorter than standard so they can be used to convert a
    standard cistern to internal overflow.

    I have a push button toilet flush system and the cistern sprang a leak. A plumber replaced the push button and now I have to prime it each time I want to flush. I mean I have to push the button 3 or 4 times before it will flush. Is this normal because the plumber told me that they are all the same.
