Have you ever experienced sticker shock from an unusually high water bill and wondered why the amount suddenly skyrocketed out of the blue?
In most cases, a high water bill is caused by a leak somewhere in your plumbing system.
With a little detective work and ingenuity, you may be able to locate the source of the leak and fix it yourself. For more serious plumbing issues, you may need a plumbing professional.
How Do You Know If You Have a Leak?
The first step is to check if you actually leaking, as there are other reasons for a high water bill, including overwatering the lawn, frequent use of your washing machine, or adding another person to your household.
To determine if you have a leak in your system, check your water meter:
- Turn off all appliances and your yard’s irrigation system.
- Outside, open the cover of your water meter and look for the flow indicator, usually a small rotating wheel. If it moves, you probably have a leak somewhere in your house or yard.
- If your meter doesn’t have a flow indicator, write down the numbers that appear on the meter. Check back in an hour. If the numbers have changed, you need to look for a leak.
Inside your house, there are several sources of possible plumbing issues to explain your high water bill. A leaky toilet is the most common culprit, contributing to about 90 percent of indoor leaks. A leaking or running toilet can waste up to 200 gallons a day or 1,400 gallons in a week.
Here’s how to determine if a leaky toilet is the source of the problem:
- The sound check. Listen to your toilet. If you hear a hissing sound, you may have a leak.
- The dye check. Take the lid off the toilet’s tank and put in a few drops of food coloring or a dye tablet. Wait 15 to 20 minutes, and check the water in the bowl. If the water has changed color, there’s probably a leak allowing water to flow from the tank into the bowl.
The cause of the leak is often a faulty or worn out flapper (flush valve) in the toilet’s tank. You can get a replacement at your hardware store, and installation is easy. Just leave enough slack in the chain to allow the flapper to do its job.
