Bottom entry cistern filling valve

Jan 22, 2011 16 Replies

The fill on our toilet has slowed down and I've found a tiny tear in the rubber diaphragm

Is it possible to buy replacements, or is it a completely new assembly

I'm looking at sourcing a new assembly, is the height relevant as long as it's

Take the diaphagm washer to a plumbing shop you will get a replacement.Not likely to find one in the sheds though.

I'll give it a try, though after a previous visit, the local guy will probably want the remaining arm and leg!

It's a Siamp -

True - they are quite wide.

I've had problems with Fluidmaster where the cistern went into a continuous syphon mode (which might be related to the syphon too). The problem was caused by the Fluidmaster's immediate opening when flushed: water (which is quite high pressure here, especially at night) would refill so quickly whilst still flushing that the syphon never broke and so would continue to dribble indefinitely. A temporary fix was to throttle water fill rate with the service valve (noisy, slow and unreliable) but the real fix was to swap the Fluidmaster for a Torbeck.

Thanks for that, I've emailed them.

Fluidmaster;

Yes, I had that with a Flowmaster so had to throttle the supply. The 'new' (about 4 yo) flush has a Siamp in/out and the fill is delayed.

'kinell £10 for a diaphragm washer! You can get the whole valve for that

used to fit Torbecks but they've f*cked around with the design (instead of the stainless steel needle that must have cost about 1p to make and fit they've got some flimsy nylon protruberance on the washer, which is no longer standard between all their valves) so now I fit Flowmasters which you can get spare washers for at not-totally-stupid prices
