Can you find/reference that????? �Seems pretty farfetched to me....

That is, I'm aware of some modifications requiring anti-scalding valves,
probably some updates are made periodically on relief valves, but an
ordinary plumbing isolation valve just doesn't seem right, logical or

sorry it was a news item cant find a link.

any spring loaded valve should provide over pressure protection, which
is built into T&P valves.

pressures from frozen pipe can reach a thousand pounds, such
protection is a good idea
