Watts 210 valves AND an exterior installed pressure relief valve are acceptable alternatives (check your area AHJ) to a TPR valves that would have their discharge lines terminate on the interior of a home.

Interior land-locked WH's are really difficult to have a properly terminated discharge line. As I've witnessed a lot of water damage from a leaking TPR valve, I'll recommend an installation of a 210, but would check in your own area.

Just a thought

That doesn't address electric water heaters.  Water damage is miserable but not as miserable as an exploding tank.

When water heaters are installed above or within habitable space they are required to be in a pan not less than 1-1/2" deep and shall have a pan drain. The pan drain shall extend full size to a suitably located indirect waste receptor or shall extend to the exterior of the building and terminate not less than 6" and not more than 24" above the adjacent ground surface

I wonder why Watts has not created a Watts 210 for Electric?>
