plumbers mate vs silicone basin waste install

[johnny2007]

In gone days I used plumbers mait, but since a few years ago a good plumber introduced me to basin mate and mcalpine traps, I don't put anything there and never had a leak.

Mait all day everyday.
Silicone is great but not for wastes.
Been there etc etc

Thanks a lot guys also another question do I need to use PTFE tape when I connect the the flexi pipe from the tap to A cut off Vale 15mm or quarter inch .

I think they are flat faced the shut off valve hut not sure .

Then i have 15mm copper running from the isolation valve .

No, flat face against a flat face usually needs a fibre washer.

Use PTFE tape where there is a tapered threaded, where the seal is on the threads. No attempt should be made to seal parallel threads, the seal is formed elsewhere.

Use nothing on a compression joint where there is an olive, or at a pinch a wipe of Mait.

or at a pinch a wipe of Mait.

Nope. Never used mait for that.
It'd be paste for me in that instance.
My preference laco liquid ptfe.

Another vote for plumbers mait. My tip, don’t need it in the fridge, use a drop of water and it becomes more pliable and find it doesn’t stick to my fingers either.
