Help! Sealing a waste pipe

[Harvest Fields]

You're right a new trap only costs a couple of quid.

Don’t go for the cheapest

Don’t go for the cheapest

Go for McAlpine or Polypipe IMO never worth buying cheap traps or pan connectors for that matter.

If you go to buy a new one, good idea, it is a bath waste you need (not a trap).

Thanks for all your advice here
Starting my shopping list with bath waste. Which sealant would you recommend? I take it would be different to the one I sealed my floor with.

I use good quality sanitary silicone sealant, Nemesis, Dow 781, Everflex 500 white or clear, you'll need paper nearby at least or ideally Wonder/Soudal/Tygis Wipes.

Make sure you make a good CONTINUOUS bead around both sides of the fitting, not too much and not to little - any gap and the water WILL get through.

ATB.

Thanks Jim! Got myself some Everflex and will tackle it later on. You guys have been invaluable.

Sorry to disagree with my esteemed colleagues.

I would NOT use silicone. Use Plumbers Mait.

It does not rely on 'solidifying' so is far more flexible than silicone and accommodates far more movement through temp variation because it 'self heals'.

Showing your age there mate. The problem is most instructions for wastes now state to use silicone.

You know W, I don't care Oddly, what has always truly driven me is to do the best job I can under the circumstances. All too often silicone can be slightly old or the surfaces slightly contaminated. With Plumbers mate neither of those things matter a jot. I never once had a call back for a waste I'd PM'd in but had a couple that were siliconed. One three times before I discovered it was contaminated and had to be chemically cleaned before the bl00dy silicone would seal to both surfaces. Never again
