I have a 3/4 pvc water line with a hose bib outdoors. The water pipe is wrapped in pipe insulation and 16' of it runs through a concrete wall. Somewhere in the wall there is a slow leak, possibly in a fitting that didn't receive enough pipe glue. Iwas wondering if liquid radiator stop leak installed under pressure would fill in leak. The label says it is good for plastic fittings. Does anyone know if this is compatible with pvc. Any other suggestions or ideas to fix leak . Thanks

Well, I wouldn't put any kind of stop leak in my water system. You said 16 foot runs through concrete wall. Did you mean 16 inches?

BIll Slater - That would be a very good way to poison you or some else in your home or all, that remark on the label did NOT mean water lines to homes or a bussness.. ( MY ANSWER IS DO NOT USE!! ::: F.B.E.
