Water leaks can be a bit tricky and sometimes the source of the problem is not easy to detect. Here are some ways to see where the leak is coming from.
Monitor water meter. A simple way to know if there is a leak in your house to check your water meter. Turn off all of your water supply and make sure all faucets are shut off. Once you are certain that no faucet is in use, take a look at the meter. If the meter is still moving, it could only mean there is water leak and depending on how fast or slow the meter is going could indicate how worse the problem is.
Check the water bill. You know your usual water bill as long as you have been using the same amount of water every month. if your water bill is going up, there must be a leak somewhere.
Check your home plumbing. Once you are certain of a leak in your home, you will have to inspect the plumbing. See if the hoses, and sprinklers are fine. Also inspect areas in your home that leak could possibly happen like under the sink, the shower, the faucet.
