Hoping someone can help!! I’ve been plumbing a while and I like neat pipe work, with bends etc. I have tried various benders but the best I find are hilmor only problem is with time it throws sets out of square, more so 22! So annoying having to straighten them by hand! I’ve tried tightening the nut and bolt going through the pivot, thinking that would be the cause. But it doesn’t! Anyone have any ideas???
