EBE-Bratt : The boss was furious because...."No good deed goes unpunished! " Mad Dog

If there is any form of check or non-return valve on that domestic system, then yes you need an expansion tank on the hot water, unless there is a well pressure tank AFTER the check or non-return valve.

Don't debate the issue — just do it.

Hi, I'm thinking it's more of a "what if" or "worst case" scenario. Ed is right than essentially nobody checks the T&P yearly, and that could be a big liability to take on. But, the more obvious problem usually is thermal expansion. Water just gets bigger as it's heated. Where will that extra water go?

Why should the boss be furious? Your fellow employee stayed there he was the safety. I don't see anything wrong with it.

Who would want to shut down an entire hotel?
