tenant says..

The toilet flush is on its way out- sometimes you need to try and flush three times. Its slowly been going over the last year

is it a case of taking the lid of and tightening something?

Probably the diaphragm in the syphon needs replacing.

The syphon will probably need removing, which can be a pain. Whilst you have it out I'd suggest replacing it with a Dudley Turbo 88 Syphon.

Its a two part syphon than can be removed in seconds without draining the cistern.

I took to long to reply! Listen to Ricky. Although buying a dump valve over a syphon maybe worth considering.

It's most likely a split diaphragm in the syphon.

  • It's a case of isolating the water to the toilet.
  • Remove the cistern from the pan.
  • Empty water from cistern.
  • Remove syphon.
  • Renew diaphragm.
  • Refit and seal syphon.
  • Refit cistern.
  • Re attach water supply and maybe overflow if it has one.
  • Test for leaks and flushability.
Any plumbing shop will sell new diaphragms, or you can cut a new diaphragm from a thick polythene bag like a rubbish sack or small 25Kg bag of gravel or similar.

If you're down the plumbing shop, it is wise to buy a new donut while there as these tend to never reseat the same and cause leaks.

There is a rubber conical washer that is used to seal the syphon to the cistern. You can use silicone or similar as a bit of a back up, but it should seal without.
