Water Shut Off's

When I go to work on anything to do with plumbing,I always ask tenant if they know where the water shut off is in the house.Water can cause alot of damage especially if you have a multi level house. About the only place for water to go is to follow the lowest place in the house, so if you have a two level house and the leak is in the top floor bathroom, the water will for sure run into the bottom floor.So if you discover a leak, you need to know where the water shut off to house is. I also mention to home owners that it makes it alot easier to work on if toilet stools,sinks etc. have shut offs on them so if the leak is at that one place, you dont need to turn the water off to the entire house, and if say the kitchen faucet needs replaced, you can turn the water off to the faucet. Here is a picture of where I installed shut offs to a kitchen faucet.
