Expansion tank replacement with a what is that?
I need to replace my leaking expansion tank. When I was investigating it I see that there is this brass (assuming) triangle shaped valve? with pipes coming from all sides. What is this? Do I need it?
There is also a ball valve in this bermuda triangle of pipes connected to my expansion tank. I don't see what it can do. It appears to be connected in a loop with itself.
