If you have been shocked by an unexpectedly high water bill lately, you’re not alone. According to WM Plumbing, a leading plumbing service provider, there are several reasons why your water bill may have skyrocketed.

Leaking Pipes

One of the most common reasons for a sudden increase in your water bill is leaking pipes. Even a small leak in a pipe can waste a lot of water over time, leading to a significant increase in your monthly bill. If you suspect that you have a leaking pipe, it’s important to have it fixed as soon as possible. A professional plumber from WM Plumbing can identify and repair any leaks in your plumbing system to prevent further damage and save you money on your water bill.

Faulty Appliances 

Another common cause of high water bills is faulty appliances. If your washing machine, dishwasher, or other appliances that use water are not working properly, they can waste a lot of water without you even realizing it. WM Plumbing recommends checking your appliances regularly for signs of leaks or malfunctions and repairing or replacing them as necessary.

Running Toilets

A running toilet can waste a surprising amount of water, leading to a significant increase in your water bill. If you hear your toilet running constantly or notice that the water level in the tank is dropping, you may have a problem with the flapper valve or the fill valve. WM Plumbing can quickly diagnose and repair any issues with your toilet to prevent water waste and lower your bill.

Incorrect Meter Readings

Your water bill is typically based on the actual meter reading of your water usage. However, if the meter reader is unable to access your meter or if there is a problem with the meter itself, your bill may be based on an estimate rather than an actual reading. This can result in a higher-than-usual water bill. WM Plumbing recommends checking your meter regularly to ensure that your bill is based on accurate readings.

Change in Household Size

If your household has recently grown in size due to the addition of new members or guests staying with you, this can lead to a higher water bill. More people in the household means more water usage, which can cause your bill to increase. WM Plumbing suggests monitoring your water usage and making adjustments to your habits accordingly.

Water Heater Issues

A malfunctioning water heater can also cause your water bill to increase. A leaking or faulty water heater wastes a lot of water and energy, which can lead to higher bills. WM Plumbing recommends having your water heater inspected and serviced regularly to prevent problems.

Underground Leaks

In some cases, the cause of a high water bill may be an underground leak that is not visible. These leaks can go undetected for a long time, causing a significant increase in your water bill. WM Plumbing suggests having your plumbing system inspected by a professional plumber to identify any hidden leaks.


A sudden spike in your water bill can be alarming, but there are several common reasons why it may have happened. From leaking pipes and faulty appliances to running toilets and incorrect meter readings, many issues can lead to a higher-than-usual water bill. By being aware of these common causes and taking steps to address them, you can save money and prevent future problems.
