Winterizing barn pipes, but not going as I had hoped. Help, please???
We had some days where the temperature dropped to 18 degrees and the pipes in the barn froze and burst. I just got done replacing them. The pipes are 3/4 PVC. I installed a pneumatic coppling in the line inside the house where it is fed from. The run is about 75 feet from the house to the barn.
I tested for water leaks and all is good. I hooked up the compressor to it and blew 70 PSI of air through. I would have thought the water would come rushing out when I turned on the spicket outside the barn. But, instead it just dribbled out. Once It stopped I would have thought I would hear the air rushing out of the spicket, but I don't. If I shut the spicket and let it sit closed for a few minutes and then open it slowly, the water and air start coming out. But, very slowly.
What is the maximum PSI I can blow through 3/4" PVC? Am I doing anything wrong?
