HI Chester

What type of tubing?

What size hot water pipe are we talking about?

What kind of shutoffs inline and how many?

What kind of water heating system (boiler, water heater/storage tanks, etc.)?

How many (if any) expansion joints are installed on the long vertical runs?

How about the hangers... any of them so tight they aren't allowing for expansion and contraction?

Does the pipe make contact going through the floors/walls?

Let me know more...
