Toilet leak

[Tay2807]

Hello!

I have a small leak in toilet. Water is trickling from the fill valve in the cistern, but also down the back of the toilet bowl.

I would like to fix it myself as I heard its relatively easy but just wanted some guidance. I am thinking it may be a washer that's worn or something?

Just looking for some advice on what would usually need replacing with an issue like this.

I have attached a photo so you can see the type of set up. Also would be great if someone could tell me the right type of replacement part for this particular type of setup.

Please dont judge the grime, this is a very old house and it will get cleaned

Thank you

The float valve is a Siamp, but the flush valve isn't. Hard to tell, but could be Ideal Standard/Armitage Shanks. It's probably the seal on the latter that has worn/limescaled/detritus on the washer, causing the float valve to fill. It could however be the Siamp and just overflowing. Does the cistern feed have an isolation valve? If yes, isolate and see if it stops trickling into the pan after a short while, if it drains the cistern then it's likely the flush valve seal.

Thank you this is very helpful. It does have an isolation valve, I will isolate and see what happens shortly. If it turns out to be the Siamp float valve, will it mean replacing the whole thing? And if it may be the flush valve seal, when replacing these parts are they all the same? I am worried I will purchase the wrong one.

Not usually, often just the washer

If it turns out to be the flush valve, you may be able to just flip it over. No they're not all the same so getting the correct one would be needed. Toiletspares.co.uk may be able to assist you with this. Failing that, you could replace the flush valve.

Hey guys, I have purchased a replacement flush valve seal etc and also replacement washer for the fill valve incase I need both.

I wondered if any of you would be able to maybe help me with how to fit them? All i know is to isolate the water and I think somehow the flush and float part will unclipped and the washers be underneath (!?)

But it would be great if I had some steps for follow.

Thank you

Yes, isolate the water, and flush the cistern. Gloves recommended as rubber deterioration can temporarily stain skin.

Siamp valve

Undo the nut by turning anti clockwise and pull away from valve.
Remove failed washer and replace with the new washer, iirc there’s a notch in the seating and a line on the new washer - these marry up.
Refit the nut onto the float valve turning the nut clockwise, ensuring the lugs haven’t come away, if they have just push them back on

Flush valve

These usually come with instructions, but:

carefully rotate the valve to undo from the bayonet, separate the washer and retaining clip and fit with the new. Refit valve in the same orientation as before and turn clockwise to click back into lugs

Re-instate water and test both.

Hi guys thank you so much for your help.
I managed to change both the float valve and flush valve washers etc, the float valve washer had a split, and the flush one was caked in limescale and has broken away.

But I now have a different issue which has left ne baffled! After replacing, I turned the isolation back on, and for a couple seconds water started but then it stopped.

And now I can't get any water flow in the cistern. Do you know why this might be? Im hoping its something simple that I have missed.

Thank you.
