Hi all

Anyone using the flap type flush devices in place of the regular syphon?
Do they simply flush for as long as the handle is held down (button is
pressed)?
Can't see how these work exactly! Can they give a measured flush?

TIA

Phil

Sorry - should have made some reference to toilet cisterns in the middle of
that spiel.

Very popular in the USA. They are held down by the weight of the water,
but when lifted by the handle chain they pop up due to an air pocket
built in. They will stay up until the water has all flushed and they
lay back down on the valve seat and the water once again keeps them
down.

Amazingly simple.

But they need replacing regularly as they start to leak into the pan. 2
years is about their life. The one I got no longer had available spares
so had to be replaced. Next time I'll get a syphon.

Isn't it just a matter of deposits building up on the mating surfaces?
I remember staying in a hotel in America where the thing WAS trickling
water in. Made somewhat annoying by the toilet being a syphon unit so
that it occasionally "dumped".

I took the lid off the cistern and wiped the surfaces of the flapper
valve clean with my finger and it was fine again.
