1. A leaky toilet
If your water bill increased sharply from one month to the next, the reasons can vary from the simple to a bit more complicated. First, do you have any new house guests who are using more water? Did you buy a new or additional water consuming appliance like a dishwasher or washing machine? If the answer is no, and nothing else had changed in your water use habits, then it's time for a little detective work. Here are some possibilities in order of likelihood.
According to the United States Environmental Protection Agency, the
is the single biggest source of indoor water use, accounting for 26.7% of consumption in an average home. A leaky toilet can run through up to 200 gallons in a day. That's 1400 gallons a week or 6000 gallons in a month. A three person household typically uses about that much, so a leaky toilet can double your water bill. There are a couple of simple ways to check if your toilet is leaking. First, just listen. If you hear a hissing noise, that's the water entering the toilet tank. If it's doing that constantly that means the water is leaving constantly as well, likely through a faulty flapper at the bottom of the tank. Another way to test for a toilet leak is to put food coloring in the tank. If the color makes its way to the bowl, you have a leak. A new flapper is an easy fix for most people, but if it looks like a different problem or it's one that you don't want to mess with, call a professional plumber. The money you spend will be made up in lower water bills.
