Hi, me and a mate have been working at this property. This black incoming mains pipe had a fitting screwed on to it, when my mate unscrewed it, it destroyed the thread. I didn't see it before this happened but was wondering if there's a fitting that can go straight on to it to start connecting up all the new pipework. We had a fitting for it the other night, it looked like an MDPE compression fitting but after we put it on the pipe it didn't 'grip' tight enough for our liking so we didn't even test it.
I think it's 3/4, so I'm thinking some sort of 3/4 to 15mm adaptor?
Any suggestions? thanks
