Water doesn't fill under cistern lid

[James1988]

Hey lads,

Trying to fix a toilet for a lady friend (to make a good impression, you know) but having a hard time. It doesn't flush, and the only it does is when I use the hose from the shower and fill up the tank with water. Once it gets to a certain point, it flushes okay, but obviously it isn't practical to keep doing this when she wants to use it!

I've compared it to another toilet in her house, and the water level is around the same on both, only this one doesn't flush.

Any help is so hugely appreciated.

What sort of flush valve?

My bet is siphon and knackered diaphragm

It's like two long barrels on a shotgun, with a fatter thing to the right of it, and a green lid at the top of both barrels which doesn't come off.

Is replacing one an easy enough job for an amateur or is it time to call the pros, if that is the case?

Got a piccy

This was taken right after a flush:

New two part syphon to make it easier next time.

Bit with the green top will need removing entirely. Flip it over and there will likely be shreds of a plastic diaphragm either replace the diaphragm or replace the whole siphon, as si above says make it A two part one so you don’t have to dismantle the whole toilet again in the future

Regarding carry out the repair it really boils down to how confident you are with plumbing
