Why Is My Water Bill So High? 6 Plumbing Problems That Could Be to Blame

A sudden spike in your water bill can be alarming, especially if your daily routine hasn’t changed. If your water usage seems unusually high, there could be an underlying plumbing problem costing you money. At Rescue One Plumbing, we help homeowners identify and fix water-wasting issues before they turn into expensive repairs. Here are six common plumbing problems that could be causing your bill to skyrocket.

1. Hidden Leaks in Pipes or Fixtures

Leaks are one of the biggest culprits behind rising water bills. Even a small drip from a faucet can waste dozens of gallons of water per day. More serious leaks—such as those in underground pipes, behind walls, or under floors—can be harder to detect but lead to massive water loss over time. If you notice damp spots on walls or ceilings, an unexplained musty smell, or hear running water when all fixtures are off, it’s time to call a plumber for leak detection and repair.

2. Running Toilets That Never Shut Off

A toilet that constantly runs can waste hundreds of gallons of water daily. In many cases, the issue is a faulty flapper valve that isn’t sealing properly. Other possible causes include problems with the float mechanism or a slow leak between the tank and the bowl. A simple test is to put a few drops of food coloring in the toilet tank—if the color appears in the bowl without flushing, you’ve got a leak. Fixing a running toilet is usually inexpensive but can save you a significant amount on your monthly water bill.

3. Dripping Faucets That Add Up

That tiny drip from your kitchen sink might not seem like a big deal, but over time, it can waste thousands of gallons of water per year. Worn-out washers, corroded valve seats, or high water pressure can all contribute to dripping faucets. Replacing a worn-out faucet component is a quick fix, and if your fixtures are outdated, upgrading to a water-efficient faucet can further reduce your water consumption.

4. Malfunctioning Water Softeners or Filtration Systems

If you have a water softener or filtration system, a malfunction can cause it to cycle too often or run continuously, wasting both water and energy. Signs of an issue include excessive salt usage, water that feels harder than usual, or an unusual increase in water usage without explanation. Regular maintenance and servicing of your water treatment systems can prevent unnecessary water waste and keep them functioning efficiently.

5. Irrigation System Leaks or Overuse

If your home has an irrigation system for watering your lawn and garden, it could be contributing to your high water bill. Broken sprinkler heads, underground leaks, or a misconfigured watering schedule can lead to excessive water usage. If you notice puddles in your yard, unusually wet areas, or dead spots in your grass despite frequent watering, it’s time to inspect your irrigation system for issues. A professional plumbing service can help identify leaks and optimize your system for efficiency.

6. Old or Failing Water Heaters

An aging water heater that leaks or operates inefficiently can contribute to excessive water usage. If your unit is over 10 years old, it may take longer to heat water, leading to more wasted water as you wait for it to reach the right temperature. Sediment buildup in the tank can also reduce efficiency, causing the system to work harder than necessary. Regular flushing and maintenance can extend your water heater’s life, but if it's constantly wasting water and energy, replacing it with a modern, energy-efficient unit may be the best solution.

How to Lower Your Water Bill and Save Money
