New to Me Indirect, how should I clean it?
I picked up a used Weil Mclain Ultra 40 indirect tank. It's probably about 5 years old and seems to be good shape.
Before I put it into service (in my house), any recommendations for any cleaning descaling I should do?
It's hard to say if it needs it or not, but once it's installed, I plan to leave it there for the next 15-20years.
