Hello guys,
I'm trying to get an air pressure test together for BC on a 110mm drain system. I have a number of 110mm bungs & an internal inspection chamber.
In the lid to the internal inspection chamber, is leaking a little air, tested with some washing up liquid & the bungs aren't brilliant either.
Is manhole grease the recommended stuff to get a tight fitting?
Thanks in advance
James
