My helpers today had to shut off the gas and later forgot to re-light my water heater pilot light. It's too late to call, so is it okay to leave the water heater switch to the on position until they come tomorrow to light it?

It would be safer to turn it to off. The controls are quite reliable, but no sense taking even the least risk. The first step in relighting it is to tun it to off.

Thanks. I thought I should do that.
BTW - I have a yellow lab, 10 yrs old. She's wonderful, but defiant and independent! "you're not the boss of me!"
