1970s Toilet Flush with two floats - help with repair

[GillObrien]

Hi all,

Our upstairs toilet is from the 1970s I think, and has a flush mechanism that I haven't seen before. You pull the small knob on the top to flush, the bowl fills up then drains. Inside the cistern there are two floats.

The toilet runs all the time into the bowl. All the other toilets also did this, but are more modern and I could dismantle them, clean everything and replace the joints. This one I can feel limescale under the bottom joint but I can't get at it.

Does anyone know how to take these apart so that I can get at the bottom joint? And should the toilet bowl be filling with water then draining when I flush?

Thank you!
Gill

It’s not one I’ve seen before either, and parts may not be available if it wasn’t popular. You could try emailing these: https://www.toiletspares.co.uk - very helpful. Failing that, you may just need a new flush valve. The passing of water is usually down to the seal being perished/not seating.

Thank you - I will do.

I found the original manufacturer (Porcher) who still exist and seem to have a similar model but with a different flush (same principle, more modern). I emailed them as well.

Could be this one: https://www.mytoiletspares.co.uk/valve-seal-66x5-5x5-porcher.html pricey if it is, I know what I’d be doing.

It looks like it. I think the ring that it sits in needs replacing as well because it is full of limescale. I have soaked it in vinegar but it hasn't all come off.

I can't figure out how to take the thing apart to get at the valve seal.

Porcher replied and asked me to send photos, so hopefully they can confirm as well.

At the moment we just keep the water supply to it turned off, flush it, turn the supply back on the fill the cistern then turn it off again, which is a bit painful.

Thank you for all the help.

You have saved the day. Finding a similar one led me to a replacement mechanism, which showed me how to take everything apart! So now dismantled, cleaned, new joint arriving (5 EUR) and all should be good

Thank you!
