Turn off water?

[LETMGROW]

If I will be gone longer than a day I shut my water pump off and the water heater off. My water system has a 3/4" line out of the pressure tank which feeds the whole house. In that line I have a 1/4 turn ball type valve. By closing this valve no water can flow anywhere.
Shutting the pump off would be alright if the pressure tank was empty. However it is either normally full or nearly full all the time. If I shut my pump off and left the feed line valve open the pressure tank would empty if I sprung a leak somewhere. It might not be a major flood but surely wouldn't be pleasant to come to.
I don't turn the heat down unless I'm going to be gone for more than a couple days. In the wintertime when we need heat up here we really need it.
We don't have AC in the house. No real need for it considering we seldom get more than a day or two of intense heat. If it gets too hot in the house I plug the MH in and run the AC(s) and sleep there.

I always shut off the incoming water line after one 3-month trip in 2005. We came home to 4" water in our walk-in basement. The only reason it was not deeper was the basement drain system could keep up with the aid of 4" water weight helping flow rate.
It took a month to clean out soggy materials, dry out the basement, treat for mold/mildew and allow time to insure it worked. Then the rebuilding process began, which took me almost 4 months working after arriving home from my day job.
Oh, the leak cause, the water softener inlet valve blew a gasket, and was out of warranty. Luckily our home owners ins. paid their share after I proved it was not an excluded natural flood issue.

I am in the custom cabinetry business and got a call from a friend to come to an other friend of his home. I got there and the couple had been gone for some time and the supply line to one of the second floor toilets gave and the water ran for about three weeks from the water bill. The living room ceiling [25x40] was sitting on the floor. All hardwood flooring buckeled cabinets ruined. In short a little over $500,000 damage. I now turn the water off to the house if gone over night.
