My first toilet fix and I have problems. Please help!!!

[honoursword]

Hi all, hope you're well.

First of all I am trying desperately to fix the toilet myself. I have told the wife I can do it so my reputation as man is at stake...lol.

The truth is all was going fine until our ensuite toilet started leaking. So thought I would replace the everything as they were starting to make noises and leaking into the bowl anyway.

I bought at my local Homebase a Fluidmaster 400K and a Cable Dual Flush Valve combi kit.

I successfully added everything and thought I would mount the cistern in the bath and fill it just to be sure there were no leaks. Didn't want to reattach the cistern to the mains and wall only to find there were problems and I had to take it off again.

So mounted it securely in the bath and filled it with water. The inlet seems all ok, no leaks but for some reason the flush valve was leaking. Not much but leaking still.

I think it is because the bottom of my cistern is not perfectly flat like most seems to be. It has grooves that I think is causing a problem with the sealing washer.

So I thought about using a sealant on both the inlet valve, the flush valve and the old doughnut that I think is still ok. However on the box it specifically says 'Do not use plumbers putty with this producet'.

So my questions are what sealant can I use? Is a sealant the best idea? Is there anything else you can recommend I do?

Apologies for the wall of text but some help would be appreciated.

Thanks very much for both you replies. Are there any sealants you can recommend for this type of job? Don't want to get something that isn't right or poor quality.

Just a good quality silicone will do.

I don’t like using silicone. It will work but the syphon and inlet valve should seal with out it really.

I only use CT-1 on loos now. Yes, you shouldn't need anything other than a washer but lets face it, in the real world you do! If you read the Prestex blurb they say put the compression fitting together dry!

What on earth were you thinking when you staked your manlihood on the repair of a leaking toilet?

You want to know whats going to happen now.... your wife will call a plumber and they will fix it in about 5 minutes.
For your sake, I hope the plumber that turns up has 21 digits!
If they only have 20, you will never live down the shame.

The dogbox for you Pal.

Carefully inspect the porcelain around the hole where the flush valve fits. Last time I had one like yours that kept leaking, there was a fine crack near the hole. The quality of some sanitary ware is quite poor these days.

See above post for the correct thing to use.

Since you're doing this DIY and time isn't a big concern then any tube of sanitary silicone will work fine but you really need to leave it at least 15-20 mins to form a skin and ideally 60 mins plus to set a bit before it will help. LS-X will work straight from the off.

If you don't already have silcone and a gun it will be cheaper to just buy 1 tube of ls-x and use that

I'm a DIYr and have replaced a few toilets in past house but the thing that always gives me pain is the 'doughnut ring' in a close coupled unit. The one I remove is always soft and pliable but the new ones are hard rubber which never squish down in the required way. Am I buying the wrong item or do the hard ones soften up over time?

IF it's Armitage Shanks or Ideal Standard, they use a special design of doughnut that is quite soft and has a round cross section and will be different from most generic doughnuts.

That could be why the ones I've bought don't work, I usually managed to renovate the old ones and used those. Thanks Ric
