Redwood, you know that this is a total load of hooey..
I do think it is something that I might start to mentioin to my customers when I go into their homes...
I would inform them that it would be a good idea to change it while I am at their home for $$ 125.00..
I will not test the T+p valve cause I know it will leak...
but I will gladly change it for safety sake
I dont think i will get many takers.....even at 125
not in this economy:confused:
Well boys, in 25 years owning personal and renting homes, never messed with them. Not worth the time etc..Most time the tank will be shot before the valve...YMMV.
Of course your water conditions may be quite different from what I routinely see.
I'm not kidding when I say bomb and you know it Mark...
Of course the need of this critical safety device is limited to a situation where the thermostat has failed causing run away heating of the water and the ECO has also failed. It is a third in line device. But it is highly desirable to have it working.
