Pvc Repair

This past Saturday my friend sheared off the main water line coming up through the floor in his garage. ITs 3/4 inch PVC. He is on a well and after it comes through the fllor it feeds an array of filters and water treatment apparatus. He restored water to his house for the time being by turning off a valve in his garage and connecting a garden hose from the well to an outside hose bib. This bypasses his filtration system.

The break is flush with the concrete slab. I thought we could drill a ring of holes around the pipe and break out a piece of the slap to get to the pipe. No can do, the concreate was poured around the pipe and this would probably just break the pipe again. We may have to try this and then make the repair below the slab. I see how we could get into trouble if the PVC splinters when we break the concrete

Another plan is to ream out the pipe a little and stick a piece of cu in it and glue it in with epoxy. The stuff you see at HD for gluing copper and PVC and whatever together

I dont know about plan B only because I am not familar with the epoxy and how well it works. I guess if its as good as the display claims this would be the way to go.

Go with your original idea, drill a lot of holes around the pipe starting approx. 6in. away, take a chisel and break off the segments away from the pipe, [concrete does not stick to plastic] repair pipe, put insulation around pipe, test line, and patch hole. Lots of luck

If you want to do it right!! Remove the concrete around the pipe - all the way to the dirt (concrete might not stick to plastic - but I can bet you a dollar it's going to damage/break it). Dig out enough to get a good piece of piping to work with - and then make your splice. When you replace the concrete - put a 4inch piece of PVC around the existing piping - and fill it with dirt - to prevent similar issues in the future.

Plan B is not good - you'll have a questionable joint - and the new pipe will be of a smaller diameter than the original, restricting flow to the house.

Thanks guys, a two beer job, after he broke the concrete it slipped right off the PVC. We chipped out the hole square and put a chimney tile around the pipe. He had the concrete broke out before I read the post. Biggest part of the job was waiting on me to bring over the pipe and fittings

Hes getting a patio poured next spring so he is going to wait until then to mortar in tile.
