A small water leak, drip, drip, drip from the faucet can add $40 dollars annually to the water bill.
A leaky toilet can add $500 a year.
Most people don't know their toilet leaks but one out of three in Tucson do.
That's why Tucson water wants people to fix a leak around their house.
That, and the fact some Tucson residents have had surprise $1,000 water bills.
There's some question whether those bills are the result of a faulty water meter or an undetected leak. But either way, the homeowner must pay the bill.
Some water users are reluctant to call out a plumber at $80 an hour or more.
And while there are times when a plumber is needed, many small leaks can be fixed by following a simple do-it-yourself video.
Tucson Water has a series of links for that too.
