Our inlet is cold water line, but the pipes are more like hoses. I don't know what they were thinking when they put them in, but they are a pain to repair. They used to put in copper pipes, but stopped doing that and now use a smaller pvc...not as big as the waste pipes...we have a well, not town water. So when electric goes out, we can't flush! Our well pump needs electricity to pump in the water. That's country life for you....but I wouldn't want to live anywhere else!
So far so good....this fix is holding Praise the Lord!
