Thiết bị & Bình nước nóngCâu 217 / 360
The temperature-sensing element of a water heater T&P relief valve must be located so that it senses:
a.the incoming cold water
b.the room air temperature
c.the flue gas temperature
d.the water in the top 6 inches of the tank
Giải thích
The T&P valve's temperature element must extend into the top 6 inches of the tank, where the water is hottest, so it responds to dangerous overheating. Sensing cooler water lower in the tank would delay relief. Correct placement is essential to the valve's protective function.
