Bathroom Plug - Sealant Question
 

In the bathroom, we have one of those pop-up plugholes which is operated by the lever on the back of the taps.

Around the plughole there is obviously the chrome rim that covers up the hole in the sink.

It seems that there was some sealant underneath this rim, which has come loose, which I then pulled out! Now, even when the plug in in the down position, the water leaks away through the gap around the rim.

So I trundle off to B&Q to look at sealants. And pretty much without fail, they all say that they should not be used in places that are "constantly immersed" or in fittings like shower trays.

So what should I use to seal this gap? Any plumbing experts that can offer some advice?

Thanks in advance.

Should you not have a rubber ring rather than sealant under this rim?

Re: Bathroom Plug - Sealant Question
 

You should be able to get silicone sealant that is formulated for bathroom use - have you seen any tubes of it, and did it still say 'not for immersion'?

Re: Bathroom Plug - Sealant Question
 

I agree its normally a rubber o ring.

.....with some sealant, just to be on the safe side :D

I'd have quick look on the floor under / around the outlet as the water now probably leaks around the *outside* of the drain pipework !

A few years back I was living in a flat, and my upstairs neighbour decided to give the bath a *good* scrub. He actually unscrewed the plughole/ring, and proceeded to rinse the bath. Luckily I was home and noticed the water running down my toilet walls :Yikes:

Corning 765 silicone sealant , guarranteed for 20 years. Any plumbers merchants will stock it

Re: Bathroom Plug - Sealant Question
 

You should make sure that the surfaces are 'flush' with each other and unimpeded with obstructions etc. Then you should use PTFE tape which will be available at any B&Q store or local hardware store. Ask one of the staff how you apply this tape to the fittings if you are unsure. This is assuming that you have not ommited to put the rubber washer that came with the fittings in when it first got installed (if there was one)

Yep, checked the silcone out (why does that sound rude?) and yes, that also said not for immersion.

Strangely there's no leakage on the pipes underneath...which I thought was odd too....so I have no idea where the water is going.

Thanks very much...I'll have a search around for that. Much appreciated.

I think that's the problem, the rim on the plughole is not comepletely flush against the basin. But without completely dismantling the whole sink unit (it's all built-in) I think I'm on a loser when it comes to putting PTFE around the pipes under the rim. Or am I missing the point? Plumbing is not my strong point (can you tell?!?!)

Re: Bathroom Plug - Sealant Question
 

hmm. Have you any recourse against the person who put it in? Did it come with the house? Is the house new?

Re: Bathroom Plug - Sealant Question
 

No. Yes. No!

Actually, I've been investigating further...the water is doing down the drain, just around the outside of the rim. The ceramic is moulded so that the plughole fitting is shrouded, and so the water is at least going in the right direction - so it really is just some decent sealant I need by the looks of things.

Can't seem to find any reference to Corning 765 on the net though.

Re: Bathroom Plug - Sealant Question
 

PTFE tape is used for compression fittings. PTFE is no good in this case.

The O ring or silicone that was under there was worn out. The plughole need s to be undone,then apply silicone in O formation under the plughole and fasten it back.

This sillicone is not under constant immersion (unless you have a jaccuzzi or similar that is kept permanetly full). Constant immersion is a swimming pool type environment. A bath is only immersed when it is full.
