My house will be vacant for about a month and I'm strongly considering turning off the main water valve. However, I have a couple humidifiers which I generally need to run because I have a lot of interior wood flooring in the house. I'd like some advice on what to do here. I see three options:
- Turn off main water valve, don't drain the pipes, leave the humidifiers on. (Not sure what problems might be caused if the humidifier is running off the remaining water in the system... seems like it could cause a problem.)
- Turn off main water valve, drain the pipes, turn humidifiers off, and just accept that I'll see more cracks in the wood flooring.
- Don't turn off main water valve, leave humidifiers on.
No matter what, I'm going to continue to run my heat pump, and I don't expect deep freeze conditions.
