Start checking for leaks by reading your water meter. Read your water meter before and after 2-hour period when no water is being used. If the meter changes at all, you probably have a leak.
There was a case in Superior last year where the water meter wasn't read for over a year. When it finally was read, the property owner found out a toilet was running in the basement for about year. Their water and sewage bills were for using close to 800,000 gallons of water in one month!!
Things to check for:
- Dripping faucets and showerheads - ensure tight connections to prevent leaks
- Toilets - over time the rubber part of a toilet flapper decays and may need to be replaced
- Irrigation systems should be checked each spring before use
- Outdoor spigots and garden hose
