Hi All,
In my quest to repipe a 70 year old house on a slab, I have created a problem that now begs for a solution... a galvanized 1/2" hot water shower supply pipe that is still leaking...
In order to bring in pex, I needed to cut the approximately 16" tall supply pipe. There was not room to wiggle the top part of the pipe away from the old Price Pfister tub/shower supply while leaving it in place. The point where the vertical 1/2" pipe meets the valve consists of a brass fitting with a lip on it that fits onto the shower valve via a union.
Clearly, the whole setup was assembled one on top of the other, since the only way to remove the supply pipes was to cut them. Since I cannot get underneath the fitting (Slab floor), I did not have the option to cut the 90 degree elbow away.
I used a sleeve pipe repair contraption on both the cold water supply and the hot. The cold is holding, but the hot leaks when under pressure. I am wondering if my best option is to unscrew the remaining piece that goes down to an elbow that is below the slab and replace it with a nipple and threaded items beyond that, try the sleeve thing again after taking it off and cleaning it, or ??? Any help will be greatly appreciated. The sleeve repair thing is only going to be in place until a water heater is brought into service for the bathroom, allowing me to abandon the original pipes for good.
Thanks,
David
