In Texas and had burst pipes in Feb 2021 so I'm a little spooked ahead of this weather and just planning to shut off water at main and drain pipes to be safe.
Have read a few different things on what to do with the water heater in this situation. I have a tank gas heater in my attic.
If I drain all my pipes, am I fine leaving the gas on current setting? Or do I need to turn it to pilot/low temp? Or turn it off completely? Currently planning on having water shutoff and pipes drained for 36 to 48 hours.
Edit: In Feb 2021 we lost power and thus lost heating and we had a pipe burst despite dripping all faucets in the house. It is very low probability that we lose power again so interior of house will be at 65-70F but if we just drip faucets and somehow have a burst pipe my wife will murder me so that's why I am asking. So just trying to be extra safe here even though I doubt we will lose heat.
Will the water heater completely drain if I just open faucets in the house or is the only way to completely drain it by attaching a hose and opening the valve on the bottom?
