leaky toilet - what's the best way to seal?
smart51 - 31/10/14 at 07:56 AM

Following on from the tiles thread, I've lifted the tiles in the bathroom and dried out the floor, only to find that the toilet leaks a bit when flushed. It is coming from the link between the porcelain and the soil stack. What is the best DIY way to reseal the join?

The best way is to remove the pan and fit a new pan connector. Another way is to dry well and use a silicone sealer that will dry if it is still wet. Or get a plumber in.

You need either a flexible connector or an offset boss connector on the waste pipe this allows for height of the tiles which is just enough to misalign the waste pipe and cause a leak. The joint should not need any sealer on a modern system.

On the fresh water side I use a braided flexible hose with a built in isolating valve as makes life easier if you have to do any future work.

As above, pull the pan out and fit a new connector. The connectors are push fit with finned rubber seals and don't need any sealant (in fact you're more likely to cause a leak by adding sealant). Make sure the porcelain and soil stack mating parts are clean and free from limescale etc.

and from old silicon from a previous bodge

You're not wrong

That's usually the bit that takes the longest is sorting the previous bodgers work before applying your own bodge

And some fairy liquid/water to help the new pan connector slip on/in easily.
I too am a fan of flexi hoses, but avoid the cheapo ones. Make sure they are wras certified. Pan connectors too, buy branded, cheapo ones save a quick but are just not as good.

My experience is that once the seal is broken/moved between loo and poo pipe getting it to re-seal properly is a problem as limescale has built up behind the seal, Re-seating loo to poo pipe without removing the built up limescale can damage the seal or make it so it will not seat properly (guess how I found out ) especially if the loo is now in a slightly different place.

Pair of rubber glove a scouring pad and some bleach all done. I refit with a run of vasalene around the seal.

Ps check after a few days that it still dry.

Thanks everyone. All fixed now. Tomorrow's job is to replace the tiles.
