One of our toilets is acting up, when you come to press the handle to
flush it, you feel no resistance against the wateer.

It is Derwent Macdee 3 part thing and uses a membrane as the plunger.
am reluctant to fit another syphon and I would prefer to repair the
broken one, but what can I use as the membrane?

Bit of medium grade plastic i.e cut from an old bag of potting compost.

I used some plastic from one of those huge bags of cat litter. Works a
treat.

Thanks, I wasn't sure of the rigidity to use. My original thought would
have been too thick to allow the water through once the syphon had started.

But isn't this uk.diy at a cheap price? :-)

I haven't looked at the failed one yet, I am suffering the 268 mile
reaction to get the g daughters back to the half way point to re-unite
them with their mother. Will look tomorrow, now I know what is wrong.
