I've replaced my current bath outlet and overflow with a new kit. It is a tight fit, as there is very little (if any) clearance between the new pipe and the concrete floor.

There are a few odd leaks, not much water comes out.

As the area is so tight it is difficult to get a good coverage of silicon in there, so I basicaly have to get in what I can.

Would I be better to use PTFE tape first on the screw fittings (plastic) and then use silicon where I can? I am conscious that a messy silicon job will lead to leaks in the future.

Thanks

Robert

PTFE tape is good for going on threads, as for the silicone, two things
Make sure it is genuine SILICONE sealant, some "silicone sealants" will dissolve in water.

why not put the silicone sealant on the part (Waste outlet in your case) before you offer it up and tighten it, as opposed to after. And make sure you let it "cure" before testing
 
Cheers breezer, I'll get silicon wherever I can!!
The sealer I have is a bathroom sealer, I assume 'proper' silicon is the clear stuff?
 
No actually it isn't. genuine silicone sealant is the stuff that smells strongly of acitic acid (vinegar to you and me) it is available in different colours too

Other sealants as i said will actually disolve in water / not stick
you can get genuine silicone sealant from

also as a "guide" it costs about £7.00 a tube, i have tried other sealants i.e low odor, bathroom, sanitry, but they are in my opinion not up to the job

Me again.

Well, I've used the PTFE tape and silicon and the actual joins seem watertight.
However my problem now is getting it sealed between the bath and the top of the pipe. I have a foam seal, but it is a bit torn as the fitting is really tight. Am I better to leave this one on and silicon it as well, or go for a rubber one with silicon?

The space under the bath is really tight, so it's hard to see if it is sealing or not, until I put the water in ! I cannot jack the bath up either as the the installer has tiled the bath in.

Any advice again would be appreciated!
 
Put silicone on both sides of the foam "washer" you have, but do let it cure after fixing but before testing
 
thanks, I'll put the silicon wherever I can !

Cheers breezer
