Water bills are based on how much water is actually used. There are a number of different reasons that can contribute to a higher water bill. Watering the lawn or garden, additional occupants, and leaks can increase your water bill. The amount of days in the billing cycle can vary from month to month and occasionally there will be an extra week of usage.
Check your toilet. The most common and most costly water waste is from a leaking toilet. Have you heard your toilets refilling when not being used or does the handle sometimes get stuck? Sometimes there can be a leak that can’t even be seen or heard but a simple dye test can help determine if there is a problem. First, flush your toilet and after it fully refills put a few drops of food coloring in the back tank. Then, wait about an hour and see if any of the color comes down into the bottom bowl. If color shows up the flapper valve or plunger ball valve in the back tank may need replaced. Do this in each toilet in the house including ones that are rarely used.
If your toilet does not seem to be the cause there are several other possibilities that can account for higher usage. Be sure to check outdoor spigots and hoses, leaking faucets, hot water tanks, water softeners, ice makers, humidifiers or sump pumps that run on water back up. If none of these seem to solve your problem you may need to call a plumber or have your service line checked for leaks.
If you have no water, there are a few possible reasons for the interruption of service:
Non-Payment or a bad check received for payment.
No billing information for a new account.
Construction or repair of water lines near your home.
An emergency outage in your area. Please call our office at 740-548-7746.
Check the main shut off valve if house has been vacant or work has been done at your house.
Freezing temperatures and blowing winds can be the culprits for frozen pipes and meters. If you have lost all water throughout the house check to see if the main service line coming into the house through the foundation is frozen. If you have lost water to only a certain area of you home check for frozen pipes along exterior walls. If a frozen pipe is not the culprit, you may have a frozen meter and will need to call our office at 740-548-7746.
