Is Your High Water Bill Due to Plumbing Problems?

If you're wondering why is my water bill so high, then checking plumbing fixtures for leaks is a must. Leaky faucets and running toilets can really cost you.

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 professional. 

How Do You Know if You Have a Leak?

The first step is to check if you actually have a leak, 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.

Leaky faucets and fixtures are other possible sources of your high water bill. According to the Environmental Protection Agency, a leaky faucet dripping one drop per second wastes up to 3,000 gallons of water a year; a dripping shower head wastes up to 500 gallons per year. The most common source of a faucet leak is a faulty washer in the faucet handle. To remedy it, shut off the water, unscrew the handle and replace the washer.

Most leaky shower heads can be fixed by using pipe tape and a wrench to ensure a snug fit. If you have to replace either a faucet or shower head, try to replace with one bearing the WaterSense label. The EPA website can help you find these and other water-efficient products

Beyond the obvious sources of indoor plumbing problems, look for leaks around the baseboards and walls near your plumbing fixtures. Mildew or mold, darkened surfaces or puddles of water may occur near leaks. If the leak is inside the wall, you might need to call in a pro to address that issue.

Outside your house, the most common causes of a water leak are your irrigation system or a cracked or loose joint in one of the underground pipes feeding water into your house. For either of these, you will need to call in a plumber versus taking a DIY approach.

Once you troubleshoot the problem, you'll be able to take the next steps for getting it fixed. If you want to be protected from plumbing problems in the future, consider investing in an American Home Shield home warranty to get the coverage you need.
