I installed a new tub and I have one leak where the new 1 1/2 plastic pipe attaches to the old galvanized pipe. The plastic is inserted into the galvanized. I assume that is the top of the p-trap, which is deteriorating, and there was a rubber gasket the plastic snugged into. No clamps, glue, threads. That worked for the last 10 years, but not now. I am having trouble finding a new gasket. I REALLY don't want to dig out that galvanized to replace it. It is in sand with about a 8x12 inch cutout in a concrete slab.

So I've checked the bolts and gasket manually for wetness. Didn't feel anything. Yet upon flushing [U]sometimes[/U] I see some water shoot from from what looks like the right tank bolt to the floor. [U]Sometimes[/U] nothing leak-like happens when it's flushed. [U]Sometimes[/U] when flushed, a bit of water drips down the toilet from the general direction of the right tank bolt. The inconsistency confuses me. If it's a bolt or gasket that needs replaced, why isn't it leaking every single flush? BTW, this issue started after two incidents. Have you ever tried to flush and it doesn't "go"? The tank starts filling but the toilet didn't flush because the handle was pushed funny or not hard enough? Well, that happened two times in a row. Took three tries to flush. I wonder if that could've messed up the flapper. The second incident is somebody was dizzy and when s/he went to flush, s/he lost his/her balance and caught him-/herself on the tank. Is that enough to misalign something or...something? Any advice is very much appreciated!
