I have some humidity issues in my basement, and obviously I need to fix that, but I am shocked how quickly the newer valves from Home Depot, Lowes and similar stores corrode. I am referring to ball valves to shut off the hot and cold 3/4 inch and 1/2 inch copper supply lines. The valves in the house when I bought it were old when I moved in, and many lasted 3, 4, or 5 years after. But some of them have been replaced 2 or 3 times since, often showing corrosion within the first year and failing after 2 years. The main shutoff to the house is 50 years old, and while not corrosion free, still works perfectly. Can anyone recommend a ball valve that meets residential codes and lasts longer?
