OK. No debris from the faucets.
I'm begining to think the lines were installed reversed. Here a symtoms:
- House was built new in 5/2002
- Gas water heater fed by well.
- Upon move-in, the hot water temp was not hot enough. I set the temp
close to max. Where it is now.
- When I first changed the filter just after the pressure tank back in 2002,
I did not turn
off the valve that is installed on the cold side just before the hot water
heater. So, hot water began to drain from the filter opening that I had
partially unscrewed. I couldnt understand this but I shut off the valve
at the water heater anyway. This worked. So from then on,
in order to change
the filter I have always turn off the valve at the water heater as well
as the valve between the pressure tank and the filter.
- Yesterday I emailed State Inc (water heater company). They suggested
to drain the water heater.
- Instructions said to turn off valve on cold side that is input to the water
heater. Turn on a hot valve faucet in the house. Turn temerature to
Pilot. Then connect hose to drain valve and open the drain valve.
- I did this up to the point of connecting hose to drain valve (not a garden
hose fitting). So the tank did not drain.
- However, the water continued to run out of the faucet for 30 minutes with
no loss of pressure.
It was completely cold upon closing the cold input valve.
- After 30 minutes, I opened the cold input valve back up and I get hot
water.
Now, there is no visible bridge between hot and cold other than the tank itself.
What do you think?
