| There are automatic water shutoff valves which detect water pipe leaks and then turn off the water supply. This helps limit damage caused by a pipe leak. Good to have this installed inside the house just after the manual water cutoff valve. |

I don't shut off my water but almost all my longer travel is when the temperatures are well above freezing so I'm not worried about the pipes freezing. I'm also usually only away for a week or so at a time. If I was leaving for months it would be different.
I have a tankless water heater, so nothing to shut off there. Thermostat is adjusted (and I program it to be back to our desired temp by the time we expect to get home. |
The automatic shutoff valves are way oversold. Even a minor leak, which the automatic valve wouldn't catch, would be catastrophic if left long enough. |
Pretty sure those automatic shutoff valves do catch small leaks. |
| Leave the heat but turn it down, say 60, unless you are planning on draining all the water from your house. When my inlaws leave for the summer they do drain the house so there is no water at all in the system |
At work once, we had a coffee machine installed with a straw sized water hose one Friday. It popped off and by Monday morning there was more than an inch of water in a nearby office, and water-soaked carpets in halls and offices 30' in both directions. Several computers on the floor were ruined. A little water can go a long way! |
How does it tell the difference between watering the lawn and a leak? |
| Do radiators in an old house still work if water is shut off? I'm new to them. |
They're in a closed system and should continue working. |
Why leave the AC on at all? If no one is in the house, what’s the point of running AC? |
It can't. |
| Turn off the water and turn down the heat. |
You don’t want humidity to build up in the house, and higher heat would be bad for any nice furniture or art. |
In fact, you should turn off the water supply to your boiler. If there is a leak you want to know about it. |
Actually it can. It takes a couple weeks to learn patterns of water use throughout the house and then can tell if something is unusual. Also you can let it know you are away so it is even more careful about increased water use. |
