donametchi said:having read several questions and replies on this site i am starting to wonder if this is a slagging site for plumbers and their practices never mind.and no you should never use any of the above mentioned sealents on a compression fitting more so on new pipe.
Agile said:I dont use sealants on new fittings and the only lubricant I use is silicone on the threads sometimes. But then I dont get any leaks either!
If joint is old and leaking then a little PTFE on the inner surface of olive.
Silicone on fibre washers, always.
Those who use paste on gas joints with fibre washers are responsible for the blockages in pipework that I sometimes have to find and sort out.
