I am pre-assembling a combination of backflow prevention valve and a ball valve as a main shutoff for the house.
Both valves have 3/4 threaded female ends that will receive threaded 3/4″ male transitions for the 3/4″ copper pipes.
The entire assembly will be connected to the incoming citywater line and then onto the house supply line using compression fittings to avoid soldering problems with wet pipes.
My question is with the 3/4″ threaded fittings – is teflon tape wrapped around several times not good enough these days ?
I recall some comments about favoring the teflon paste instead.
Although the whole assembly could be easily removed I would rather not have to do that.
Which is more commonly used these days ? Paste or tape ?
Thanks for your help,
