So one of the first things they want to do is learn where their water meter is and how to read it. When you look at indoor water use you should be using between one and half to two thousand gallons per person per month, typically. So if they use higher than that for indoor uses then they will probably have problems like leaking, plumbing, high volume fixtures and other opportunities working against conservation. While they are at a water meter, they can also check for leaks. A water meter has a dial on it and if you are not using any water in the house that meter should be at a complete standstill. If you go out and you look at that meter and you see either the leak detector, which is easily a small dial that will just spin if water is passing through the meter or the very slow motion on the needle on that meter, then you probably have a leak in your plumbing system somewhere and contrary to what most people think of is leaks and typically think of a leaking faucet and dripping faucet or something that's visible, most leaks and the most damaging leaks are typically below ground where pipe has a perforation or a fitting begins leaking and those kinds of leak can not only lose thousands of gallons of water every month, there is sometime even tens of thousands of gallons of water. They can also do severe damage to the property that you wont know until it's too late. So starting at the water meter and checking for leaks would be a great place to start.
