Its been about a month and yet again it leaked a bit today, cleaned it up and put some pieces of toilet paper to make sure it had stopped leaking. Noticed nuts holding down toilet were hand loose so I tightened them. This current installation(s) were good for a month then it leaked. I imagine if there was a crack somewhere it would leak slowly and constantly as I have had toilet paper around the base to detect leaks. If you look at my pics the flange bolts they slide into a notch in the lead liner is that correct? Looks like lead liner was pulled up bit to allow bolts to slide in and when liner is flat it holds it in place. Is it normal to be able wiggle bots a bit? Should I use a plastic washer underneath the brass ones in the pic? Also lead flange isn't smooth like a plastic one, it does have some irregularites and I don't see any cracks in it. Should I use shims? At the front and back of the toilet there is no gap to speak of. In the middle around where the bolt holes there is a gap. I'm at a loss, tried 2 toilets, wax ring on flange first, wax ring on toilet first. I guess I should have hired a plumber from the get go and had it done "right".
