WC Siphon Diaphragm

[andrewstokes87]

Sorry if the title is spelt worng! I have just been to a customers toilet which isn't flushing I diagnosed the problem as a torn diaphragm. It was a nightmare to strip down due to whoever installed the WC had used silicone all over. Eventually I stripped it down and replaced the torn part and then put it all back together turned it on and its still not working! I told the customer it was a simple job and should take an hour tops its been four hours now as I have had to fetch a new fixing kit and so on but it still doesnt flush. I have now tried to get a siphon but they are all too big as this one is really narrow. Does anybody know why this would still not be flushing?

Thanks andy

Check for splits/holes in the syphon itself.

Had this before blasted toilets whats with them.

Best thing to do is take it out and replace it with a flapper, made by fluid master, once you've fitted one you'll never use a syphon again.

You're not getting a proper seal between pan and cistern. Probably the reason for the use of silicone by original installer. Use a sponge type donut washer not the thick rubber ones. They come in two sizes, 2" and 1/12". If possible change to a Fluid Master cable flush syphon. I'm assuming this is a close coupled toilet.
