I spent all day Saturday fixing a hot water line leaking under the slab in my daughters house.
Here you can see water coming out of the pinhole leak. The eater from the hoteater tank was shutoff. This was the water left sitting in the pipes.
For some reason there was a gap in the vapor barrier and some of the pipe had cement on them.
Bad section cut out. Now time to clean up the copper pipe.
A coupling and slip coupling with a piece of PEX in between. I didn't have much room to work, so the PEX piece in the middle is 2.50" long (1.25" + 1.25"), just long enough to engage both Sharbites. I wanted a 0.25" inch gap in the middle but i got tiredof trying to wire wheel and sand all of the cent and crap off the pipe, and the closer it got to the edge of this hole the harder it was to work.
I spent 12-hours removing the ceramic tile, cutting, hammer and chiseling through that tough ass concrete, going to Lowes for parts, cutting the pipe, cleaning the pipe, smoothing it with 600 grip paper, getting the fittings on, and then getting the slip coupling to slide into the other joint. This copper pipe was slightly bent so the coupling didnt slide easily.
Went back over today, made sure it wasn't leaking, wrapped it with sharbite tape, filled the dirt/sand back in, put down some plastic, and then covered that with concrete.
They have left over floor tiles. My son-in-law will reinstall the tile.
It was going to cost them thousands to have a plumber fix this. Doing it ourselves cost them about $110.
On a side note, I got electrocuted twice before realizing the cord on my drill finally worn to the point there was a small section of bare wire exposed.
I wasn't even using it. I just touched the cord while I was on the floor working. Wasn't sure what shocked me the 1st time.
I hate that feeling.
I hate plumbing. I've done to much of it lately.
