atwood 10 gallon water heater
my water heater in my rv leaks out of the pressure relief valve when the heater reaches 140.

RV water heaters have 'air pockets' for expansion..water expands when heated and does not compress. Air does.
RV water heater 'normal' t-stats open at 130/140*F (pre-set fixed temp)
RV water heater 'High/ECO' t-stats open at 170/180*F (pre-set fixed temp)
RV water heater 'Press/Temp Relief Valves' open at 210*F/150 psi
RV water heater PRVs temp probe are submerged in the water below the air pocket
Dripping from PRV's is when heating water is typically due to loss of 'air pocket'.
Turn off water supply
Open hot side on faucet to relieve pressure
Open PRV via lever until water stops running out...then let it snap closed
Turn on water supply
Close faucet.
