But if you want to put it in your home, go ahead. It's your home. You just
probably won't find an experienced licensed plumber, you know the people
who do this work for a living and are educated in it, who will risk his
license to do it for you. Hope this helps!

There's another issue as well. If a guest is scalded when using your
shower, and sues you, the insurance company will investigate to see if
the valve was ever replaced. If it was replaced after the requirement
for the scald-proof valves then they will want to know who installed the
valve. If it was a licensed plumber then they'll go after them. If it
was the homeowner it gets dicey. The homeowner violated the code by
installing a non-compliant valve so the insurance company could refuse
to pay.
