Opening your water bill to find an unexpectedly high number can be frustrating. The good news is that you can reduce high water costs by fixing their sources, which can include hidden leaks, outdated plumbing fixtures and everyday water-use habits. Learn how to identify the causes of high water bills and protect your home from costly hidden water damage.
Why Is My Water Bill so High? Uncovering the Common Causes
If you’re wondering how much your household’s water bill should be, the typical costs can vary by usage and local rates. However, if you’ve noticed a sudden spike or your bill seems unusually high compared to previous months, it’s time to investigate the causes.
Hidden Leaks
Even tiny leaks can cause the biggest source of water waste. According to the United States Environmental Protection Agency (EPA), household leaks can waste more than 1 trillion gallons of water annually.
Common culprits include worn toilet flappers, corroded faucet valve seats and underground pipe leaks. These hidden issues can steadily increase your average monthly water bill without visible signs, leading to a buildup of costs over time.
Aging and Inefficient Fixtures
Older toilets, showerheads and faucets use more water than modern versions. If your home still has fixtures from decades ago, you’re probably using a lot more water than necessary.
By replacing older toilets with modern low-flow fixtures, households can save nearly 13,000 gallons of water each year. This reduction adds up to significant water savings over time.
Everyday Habits and Appliances
Daily choices make a bigger impact than most people realize. Some habits that contribute to higher bills include:
- Taking longer showers than necessary
- Running a half-empty dishwasher or laundry machine
- Leaving the faucet on while brushing your teeth
The debate over dishwasher versus hand-washing water usage is worth noting. Using a modern dishwasher, such as a new ENERGY STAR-certified dishwasher, can save over 8,000 gallons of water over its lifetime compared to hand washing.
Water heater temperature settings also play a role. For example, if your water heater is set too high, you’re encouraging more hot water waste throughout the day.
How to Lower Your Water Bill
Follow these steps to see the biggest savings.
1. Schedule a Professional Leak Inspection
While you can check for obvious drips yourself, a professional inspection is the only way to confirm you’re not wasting water. Many expensive leaks happen under your foundation, in your walls or in underground service lines. Professional plumbers use pressure tests, thermal imaging and acoustic leak detection to find hidden problems.
2. Upgrade to Water-Saving Fixtures
As we have covered above, modern fixtures can help you save on water bills. Examples include:
- Toilets: Toilets certified under the WaterSense program use significantly less water than older models while maintaining strong flush performance. The installation cost is often recovered through lower utility bills within a few years, and you’ll continue saving money for the life of the fixture.
- Showerheads and faucets: Low-flow showerheads deliver strong pressure while using much less water than traditional models. Quality models are often considered affordable and typically pay for themselves quickly. Faucet aerators are an even more affordable upgrade that reduces flow without any noticeable difference in performance.
3. Optimize Your Home’s Water Habits
Once you’ve addressed leaks and fixtures, small daily changes can also make a significant difference. For instance, if each person in the U.S. used a water-efficient showerhead, it could save a combined 260 billion gallons of water per year.
When considering bath versus shower water usage, showers typically use less water overall, especially with a low-flow showerhead. However, long showers can quickly exceed the water used for a bath, so keeping showers brief is key.
Other changes you can make include:
- Running your dishwasher and washing machine with full loads
- Thawing frozen food in the refrigerator overnight instead of running water over it
- Keeping a pitcher of cold water in the fridge rather than running the tap until it’s cold
- Watering your lawn earlier in the morning when the evaporation rates are lowest
These adjustments can help you reduce water consumption significantly without sacrificing comfort.
