Water Heater Question

When I winterized my AI, I bypassed the water heater. Now that winter is over, can I leave it "bypassed" if I don't need hot water? Or, is it bad for the water heater to go unused?

Shouldn't hurt a thing.

If you are going to leave the water heater unused for a prolonged period of time take a sealable plastic bag and put math balls in the ball. Seal it and then poke 20 or so holes in the bag with a pin and put in inside the outer cover. I would also drape a plastic bag over the face of the heater and colse the cover on it. This should keep spiders and other bugs from nesting in the burner tube.

I am assuming you drained the heater when you winterized. When you go to use it just crack the bypass valve while filling the heater. This will keep the sediment from being kicked up and you having to clean each faucet screen.

There may be some merit in leaving it empty when unused. We had a rotten egg smell from the hot water heater after water sat in it a while. Old cold water never smelled bad. To overcome the smell I put a gallon of vinegar in the heater and let it sit on the bottom for a few days. This dissolved whatever nasty sediment was in there. I then drained and flushed.
