Guys

I'll askin here, since DIY is generally pretty dead

I had to fit a new drain to the bathroom sink
During testing, it leaked probably due to the crap almost plastic like seal on the basin side, so I put a little bed of silicone in and then fitted it
How long realistically does silicone take to dry - the tube said 24 hours
Surely it must dry faster than that?

Cheers

The tube says 24 hours.


I would guess...


...24 hours

Normally, about 24 hours. Did you apply it underneath the flange too? If you didn't, you may find that the sink emptys with the plug in

There's nothing like putting silicone into a flange!

no idea what you're on about
Underneath the outside of the metal rim just

Put the silicone on both sides of the rubber seal.

And after all of the above


You can use the basin straight away , the water won't get through it

Silicone?

I can NEVER understand why folk use the stuff except for what it's designed: a sealant for around baths, sinks etc.

It's NOT designed for use as you have described. You want to hope you never need the joint off again, since silicone doesn't give easily.

The best stuff to use would have been something like this:http://www.google.co.uk/products/cat...ed=0CGUQ8wIwAQ

Non-setting, but seals perfectly. If you HAVE to open the joint again, you will be able to.

Screwfix sell it, as will any decent plumber's merchants.

Should I have put the stuff on both sides then?

I only put it on the bottom of the rubber/plastic seal

Alcazar - with plumbers mait, should one put this on both sides of the rubber seal?

I have a tiny leak today, but it looks like its on the waste pipe connection into the sink drain

Really?

Yes, both sides of the rubber/plastic washer and on the metal flange that seals against the basin.

I hate plumbers mait, it's a pain to work with and I have taken a few out that have been siliconed in, no big deal tbh.

Check with some tissue to see where it is leaking, start at the top and keep checking it to see where it is damp, it'll probobly be coming down the threads and onto the trap.

Wee tip for anyone else with this sort of problem

I've just been out and bought something called basin mate
Best £2 I've ever spent!

No more leak -job done

Oh - and no problems for me removing the waste and the remaining silicone either

Yes

I've done loads of plumbing, both here and in France......French stuff is quite expensive, and where we have 15mm and 22mm pipes, theirs are 8, 10, 12, 14 16 18 and 20mm. Connections are therefore an utter minefield
Pipe THICKNESS is always 1mm, so that a 14mm pipe slides inside a 16mm, and can then be soldered.

Many joints there are brazed, or even silver soldered due to higher pressures, mine is around 6bar.

Newer installations use PE tubing, either on it's own, or ina flexible conduit, red for hot, blue for cold. Cheap and easy, but the joints are wickedly expensive.

I have too, but I am a plumber
