How to stop toileting dripping constantly

[Dazgrego]

Hi. I was hoping someone could advice me
I’m getting a constant dripping from the part with the arrow on. Sometimes it’s faster but never stops.
Can’t work out why or how to fix it

can anyone advice please

Inlet valve not shutting off completely.

Either because inlet valve is knackered - replace diaphragm, or replace whole inlet valve.

Or because flush valve is letting by, dribbling into pan. If this happens before cistern water reaches overspill level - then replace/clean flush valve washer.

ok I see. I can’t seem to find the excact inlet value anywhere online. Can I replace it with any one around ?

 

[Ben-gee]

Yes you can, as long as it physically fits and the ‘float’ is not restricted by the cistern walls.

If that's the original Armitage Shanks/Ideal Standard inlet valve, they never are that good, to be frank. Yes, just replace with another inlet valve.

I like the Torbeck Ecofil ones, but I'm sure every plumber has his or her favourite, so just with the flow.

Thank you. I bought one. Can’t seem to take this off. Is it a special tool of summit. Can’t take old one out

 

[Ben-gee]

No. Unfortunately that lavatory was designed by a special tool.

You have to remove the cistern from the pan in order to remove the inlet valve, I know it’s daft but that is design over function for you.

And then if you take the cistern off you will probably need a rather expensive Armitage Shanks doughnut washer which ain't the same as standard doughnut washers. Unless you bodge it with silicone which I would strongly recommend against.

If you aren't a plumber, it may be easier to service the existing valve and replace the diaphragm 'washer', if needed. See page 6 of link: https://fastpart-spares.co.uk/Instructions/E080601.pdf . Or call out a plumber?
