Can my WC flush valve be repaired in situ?

[Mottie]

Just lately, every couple of hours or so, I hear the WC fill valve open for a second or two. Looking carefully, I can see that there is a very small leak from the flush valve so the water level is reducing and the fill valve opens to top it up. It’s a back to the wall WC and it’s a real agg to remove it to split apart so does anyone know whether there are any serviceable parts inside (the main seal?) that can be replaced while it’s still bolted in. If I have to remove it, I’ll replace rather than repair but if it’s a fix with everything still in there, I’d prefer that.

Well that is for the flush valve, can you post a picture of the fill valve from the side once you have flushed the toilet.

Turn off the water supply to the toilet, pull up the white arm and turn 90 degrees, the top should come off and you could then replace the washer.

Looks like it’s more overflowing by the inlet valve filling too much.

No, definitely not. The water level goes up too but not over the overflow tube. After some considerable time, it drops to almost an inch below that before the fill valve kicks in for a couple of seconds or so.

pull up the white arm and turn 90 degrees,

What white arm? I tried turning the whole thing (overflow tube is part of the valve). All that seemed to happen was the whole thing turned until the tube came in contact with the cistern. It felt like it was unscrewing from the big plastic nut that holds it in. I think I’ll leave it until later in the week when Mrs Mottie is off to Spain with her mates before taking it apart.

So if its not the fill valve then just replace the flush valve, see my first post.

Must be bad photo then:

I am not a plumber.

My Oli in wall cistern started letting water drip in to the pan (after about 15 years). Fortunately on the reverse side of the flush plate, they provide a replacement rubber washer for the underside of the flush valve.

Just replacing the rubber washer fixed things for me.

Admittedly, mine is a push/click system.

Yeah, it is the flush valve. Tried turning it and no joy as in my post #6. Guess I’ll have to take the whole bog out and it’s usually a bit of a pain. Can't get at anything until it’s removed in one piece. This type:

Mottie, go and buy the flush valve I said in my first post, you will see how it comes apart. Then just replace the top section.

Just have. All done now. Like an idiot, I was trying to turn the whole body, not just the top section!

I now consider myself a fully qualified plumber.

You have helped me in the past, so I was making sure you got it sorted!

Just corrected another **** up. Mrs Mottie wasn't happy with the protruding button and the new cable assembly wouldn’t fit the original recessed fitting button so I told her that’s just how it is and she begrudgingly accepted it.

Anyway, it wasn’t till a few hours later I opened and read the instructions before I threw them away and feck me, the collar is removable for a recessed fitting! What a donut I am!

All sorted. Happy wife, happy life.
