First time poster.
I just started as a CPO on a 137,000 gallon YMCA pool less than 6 months old. We heat the pool with a shell and tube heat exchanger run off the boiler. I noticed that the heat exhanger is plumbed in using plain old black iron pipe. Is this going to last or will it be rusting out in a year or two? How long will the brass valves and copper propress last?
