PeterW Posted March 13, 2020 Share Posted March 13, 2020 You may get 5 degrees overall but you need to make sure it is not too far out as the seals / tolerances on decent fittings can be pretty tight. Also worth ensuring you use decent silicone lubricant - not expensive and much better than washing up liquid especially if you want to split joints or adjust them after fitting as washing up liquid dries very quickly. 1 Link to comment Share on other sites More sharing options...
ToughButterCup Posted March 13, 2020 Author Share Posted March 13, 2020 ? Dave. I'm trying to get it right enough so that my mate who visits occasionally - the roofer - the retired feminist - doesn't wince and clutch his withers when he sees my workmanship.? He has a series of one liners that would make even an Army NCO splutter..... tea spouting out of your nose type remarks..... Link to comment Share on other sites More sharing options...

I spent an hour yesterday chipping out concrete all for a couple of degrees misalignment. Bloody German heritage....it's a curse sometimes no substitute fir getting “it right”.

Oz07 Posted March 13, 2020 Share Posted March 13, 2020 Deffo silicone as opposed to fairy. Too much link will not be good but you will know when you test. 1 Link to comment Share on other sites More sharing options...
Nick Laslett Posted March 18, 2023 Share Posted March 18, 2023 Sorry to resurrect this post, but just doing my SVPs and this whole angle thing is nuts. If a branch has 87.5° angle then the horizontal pipe naturally wants a fall of 1/23 according to my understanding. But building regs have max fall of 1/40. I guess there is enough wiggle to get a shallower fall. I agree about the silicone lubricant, makes undoing the fitting an actual possible.

Everyone in the trade just calls them 90's I bet you get 5 deg or more of play in a fitting ...Sorry just re read been covered already Edited March 18, 2023 by Oz07 Link to comment Share on other sites More sharing options...
