Right after I bought the property my friend M helped me get running water into the bathroom. We dug around and found where the pipes ran, and found the break in the pipe. As a quick fix, we ran the new PVC pipe over the ground. It was April and I expected to have all new water lines put in by late fall. That didn't happen, thus the trip up there yesterday to cover the pipes.
The line running from the street is 1/2 inch pipe so that's the measurement I used to purchase those gray foam insulation tubes. Unfortunately, I forgot that my friend M used 3/4 inch pipe when he did the repair. Fortunately, I bought 14 of those insulation tubes so I was able to put one wrap on and then use another one to overlap and cover the gap. I taped it in place and hope it will be enough.
Again, I'm not a professional and only had a few hours to get this done. The water is turned off at the shut-off valve and I flushed the commode twice while I was there so there's no water in the tank or bowl. I left a small electric heater in the bathroom turned on to the lowest setting. When I came inside once during the pipe covering exercise, I heard the heater come on and then shut off after about five minutes.
It was 40⁰ and blowing 15-20 mph when I left at 1:30m. Hopefully I can get back up there next week.
