Which of the following is prohibited between a water heater and its T&P relief valve?
a.a listed dielectric fitting
b.any shutoff or check valve
c.a temperature sensor well
d.the tank tapping itself
Giải thích
No shutoff, check valve, or other valve may be installed between the tank and the T&P relief valve, because it could isolate the valve and defeat over-pressure protection. The relief valve must sense tank conditions directly. Only approved fittings that do not restrict operation are allowed.
