Have a few questions concerning the valve on our water heater. It is in our
mobile home and is about 6 years old. The wife got hot water for about 1/2
bathtub of water. I went out to look at the heater and the pilot was going
but not the burner. I started rapping on the valve and thermostat housing
and the burner came on. So apparently the valve was stuck. So now my
1) Is this a sign of more frequent problems?
2) Can this housing, valve and thermostat be replaced easily, or at all? If
so is it worth it on a 6 year old heater?
3) If the valve can stick closed, can it stick open allowing the burner to
Thanks for your input here, I know little about this.
You're right to be concerned. The valve could just as easily
The complete control is indeed replaceable, but on a 6yr old
heater not cost-effective IMHO. The control alone will cost you
close to $100. That's a good fraction of a new heater cost.
Gas heaters have an average life of 10 yrs.
There's a good chance it will happen again, and with more frequency. There's
also a slight chance that a little piece of dirt got in there, and you
dislodged it. This happens once in a while, especially when there's no 'drip
leg' installed on the gas piping. Call a repairman and ask the price to
repair or replace your water heater. The life expectancy of a water heater
depends a lot on the water in your area and capacity vs. demand. You might
want to wait to see if it happens again before making a final decision. If
you decide to replace the whole thing, consider an energy efficient model
that uses a lot less gas.
Not a factor with a water heater. If your house heater is not being used
for days or months, there is no reason to keep a pilot light burning. If
you are not using the oven for hours or day, there is no reason to keep a
pilot light burning. Hot water, OTOH, is kept hot and ready to go at all
times. The pilot light will give off some heat to maintain temperature
between uses, thus, very little if any real loss. If not for the pilot, the
burner would cycle on and off more frequently.
