I turn off the water where it goes to the rest of the house so in the unlikely event that we lost heat and the house froze that I would have less of a mess. We keep the house at 55F when we are gone and have a number of ways of monitoring the temperature.... our Blink cameras and Sensi internet thermostats.
Any issues upon return?
I do. We're on a well, so I just turn that off and drain the pipes. I put marine/RV antifreeze in anything with a trap, and I put plastic wrap over the toilet seats and tanks to slow evaporation. I turn off the water heater.
The only issue I've had is that I seem to have to replace the toilet flappers fairly often. They tend to leak/run after sitting for 6 months or so. It's a really cheap and easy fix though, so I don't worry about it. I keep a box of them around.
For those of you who snowbird, when you leave home for a few months, do you shut off water completely?
If you do, are there any issues with the the faucets, toilets, dishwasher, water heater, etc. upon return?
