Drippy Toilet - help needed identifying part

RonnieL

Hi,

One of our toilets is dripping constantly. I can see where the drip is coming from (see attached). Do I need to replace the whole fill/flush valve or should I be able to replace just the bit that's dripping. Links would be much appreciated! I've obviously tried tightening stuff, but the drips just keep on coming!

Thanks!

Replace the entire valve, easier option. I think you're unlikely to find a replacement for that fill arm

I'd also advise that you replace the whole unit as these things are a pain to troubleshoot.

For info, this is a "Torbeck" style cistern valve.

It's probably the diaphragm washer that's gone. If you can identify the correct replacement it's an easy fix.

The float is set quite high, could it be over-flowing ?

Thanks for the reply. I did try various heights for the float, but the dripping continues. If I pull the float up by hand I can make the dripping stop - not sure if that is a useful piece of info or not!

I would change the inlet valve it's easier and quicker.

It's a bottom fill and for the sake of a few quid I would get one with the brass shank.

A new diaphragm will likely fix it, turn off water, unscrew, take out rubber diaphragm, travel to plumbing store and get a €2-4 replacement.

Just don't decide to take a look late on a Sunday evening and put your finger through the aged brittle diaphragm when the toilet line doesn't have it's own shut off valve as I did before :)

Eventually got around to actually doing this. Bought this cheap and cheerful number from screwfix:

It's working, but the water is still running into the toilet bowl, so I guess the actual problem is with the other bit (that attaches to the flush buttons). Are those fairly standard, and easy to fit, or is it plumber time?

The siphon could have an internal overflow that the water level is coming above, try and set it to the lowest and see if it still flows and then raise it as much as needed.

Replacing the siphon is a bit more involved but possible to do (look up some youtube videos), a bit more dismantling of the toilet is involved.
