Pourous copper tubing (?)
Converted to gas heat about 1 1/2 years ago. Main house is steam heat, family room is hot water heat. My problem is with the hot water heat. I am lossing the water in line. To date we have had to replace the circulator pump twice as the units are failing due to lack of water. There are no water leaks in the system. Today the two check valves were replaced. So far so good.
If this latest repair fails, and I hope it does not, I am being told that the copper tubing in the hot water system will have to be replaced since the copper tubing has become pourous. The tubing is about 25 years old.
Has anyone ever heard of copper tubing and/or copper fittings becoming pourous?
Thanks for comments and help.
