Lavatory syphon problem

Apr 19, 2010 8 Replies

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.

Roger Cain explained :

A builders plastic refuse sack?

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

You can buy membranes in any plumbing supplies place for under a squid.

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.

Thanks, when I see my local builder at lunchtime, I'll ask him for some.

I'll be off looking Tuesday. Thanks.

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.

Cheers Dave
