: : : Hey!
: : : For the past few months we have noticed that when we first turn on the hot water, it's orange for a few seconds.
: : : We did'nt think much of it, until yesterday while my wife was in the laundrty room, the relief valve blew (scared the crap out of her!).
: : : Now, everytime the heater "heats" (Sears, gas, 1991), the relief valve drips. The water is also VERY orange, almost brown with rust.
: : : (just the hot...not the cold) It seems to be pressure, not temperature that makes the valve leak, as I can turn on a nearby faucet and it will stop.
: : : How long do water heaters last? This one is 7 years old...Is it dying, or do I just need a new relief valve.
: : : The house pressure seems the same, do I wouldnt think it's the PRV.
: : : (by the way, we've only been in this house 6 months, so we don;t know if the heater
: : : has been given regular maintenence.)


: : : Idea's?

: : : Thanks!

: : : Barry

: : Hot water heaters have different warranties 5yr,8yr&10yr. If you heater leaks before your warranty expires you should able to received a replacement heater and the balance of the warranty. As for your leaking relief valve it should be replaced with a new T&P relief valve. The rust can be flush out of the tank. Hook a hose on the drain valve and flush out your tank until the water is clear.

:
: This may seem like a stupid question, but how long should it take to "clear out" a 450 gallon tank? I let the water run for over 30 mionutes (with a hose on the"drain bib"). It never did run clear, although it did get a little lighter...
: This is probably the first time since it was installed tyat it has ever been "purged". In addition to the water color, I saw many particles & flakes when I performed the procedure you suggested...


OOOPs...I mean 40 gallon...
