back to article One click, one goal, one mission: To get a one-touch flush solution

I have a self-flushing toilet. Not one of those novelty models from Japan, mind. No indeed, my self-flushing lav uses a unique system; it must be a DIY job, er, I mean a custom build. But what do I know? I had a peek inside and the insides are so unfamiliar I may just as well have been staring into an alternative toilet …

    Avantgarde flush mechanisms are great until they need fixing.

    Just pop down the local DIY store and grab the cheapest all-inclusive kit they do, Mr Dabbs.

    Otherwise it'll be many more "Pffft"s, shrugs and €€€s.

    (BTW It will turn out to be the o-ring silicone seal that absorbs water and causes water-filled bubbles on the surface of the seal. Just prick them all with a pin. Takes a while but is very satisfying.)

      One worse has to be Leroy Merlin. Their Cotê D’Azur branch is just off an almost unmarked road which, if you miss it, puts you right into the A8 péage. The store is up a long winding roads at the top of a hill which peters out to a track before you see the entrance. Store service makes you long for the occasional insult you get at Castodrama or even (what my nearest and dearest calls) BalsUpitrand.

        The only way to be both sure, and considerate of others, is to wash both before *and* after pressing the button/ lever/ whatnot. :-/

          That reminds me of a cruise ship we were on where there was a sign instructing you to use a paper towel to open the toilet door on exiting, but then didn't provide a bin for the used paper towels thus promoting the spread of whatever nasties (probably norovirus back then) that they were concerned about.

              I've seen those, but you still have to find a cubicle that is clean enough that you dare sit down (I sometimes take wet towels in to clean the seats because of the scumbags who insist on using cubicles for a Number 1, then do it all over the floor).

              But that reminds me of a toilet in a restaurant in Switzerland I was in in the 1980s. It was either Verbier or Zermatt.

              The seat had a motorised plastic sleeve. When you pressed the button, a new length of sleeve was pulled around so you always sat on a clean seat.

                  The formula one (cheap staff-less motel in France) had toilets that automatically cleaned everything when the door was closed for the second time (so as not to wash the user) - my daughter was convinced that the pervasive moisture was a user failure and would refuse to go in. The problem with little children if you have to go in and out to help and encourage them is remembering not to close the door twice with them inside.

              Back in the mists of time, when I studied chemistry, it was very much more important to wash your hands before, than after, the skin on your hands being somewhat thicker, and less permeable, than skin, *ahem*, elsewhere.

              Of course, this is on top of wearing suitable gloves, using a fume hood, etc., and as a student, most of the chemicals commonly used were fairly innocuous, but it is important to teach good habits, to avoid ending up like Karen Wetterhahn.

      Re: Thank you for drawing my attention to these devices

      This is just where technology and the use of it has gone completely bonkers. Exactly why does a toilet or tap need any form of electronics in it?

      Handles and more recently push buttons have proved adequate for years only requiring the occasional washer of valve to fix.

      I get the sensors in public toilets, particularly on the urinals but on taps etc, just stupid.

      Even the fashion for the valves rather than siphons has created more issues with them leaking more frequently and the leak often unseen as the overflow is into the bowl. I know there was a lot of fuss about how the valves reduced water usage as they could "dual flush" but with the push to reduce the size of the flush it is now so inefficient, the small flush is useless and the big flush often fails on "solids".

      Net result more water used instead of having one slightly larger flush.

        Re: Thank you for drawing my attention to these devices

        Precisely. Why the need for extra 'smart' bits that will go wrong within a few months (just after the warranty expires)

        Our facilities team took the opportunity to revamp our toilets during office lockdown closure.

        Nice one, they were looking a bit worse for wear but they still functioned.

        We now have fancy new toilets with electronic no touch flush senors, but and here's the kicker, after installing them they realised there wasn't any power by the new cisterns so they had to use batteries to power the flush. Normal triple A's!!!

        Pathetic! Now every three or four weeks the toilets clog because the sodding batteries have died.

        To make it worse everyone is now petrified that it won't flush after they've used the toilet so everyone is flushing once before they use it to check it's still working!! Batteries run out twice as fast.

        Re: Thank you for drawing my attention to these devices

        Having recently fitted several dirt cheap Wickes loos with dual (4 litre / 6 litre) flushes I can safely say that they seem to work perfectly well. Problems I've seen in the past (even with old-fashioned flushes) tend to be down to dodgy waste plumbing - if the loo isn't quite level (particularly front-to-back) it can cause problems, as can a too-tight bend immediately behind the pan or maybe a pipe which doesn't "fall" properly.

        At least we have 4" waste pipes around here, rather than some other countries which seem to try to force everything down to 3" or even smaller.

        Our own toilets are flushed using rainwater. We have a 7,500l tank under the garden which takes run-off from the roof, and a 24V pump which (now) runs from solar-charged batteries. Last winter it ran from a mains transformer - I'm interested to see how the system works over the winter this year. So far there has only been one day when the battery charge has risked getting too low to run the pump. I could put bigger batteries in, but they get quite expensive.

        No, it'll never pay back - the price of potable water in our part of the UK is under 1p per 6l flush - but we have historically had a lot of problems with getting rid of rainwater around here, so flushing some of it down the loo helps considerably, and gets us a discount from our water bill - the "surface water rebate".

          I think 1 pee per flush is the standard most places. Unless you have a chronic water shortage, in which case the "If it's yellow let it mellow, if it's brown flush it down" rule applies.
