If your water bill suddenly jumps in the summer months, you’re not alone—and it’s not always as simple as “using more water.” While warmer weather naturally increases water usage, an unusually high bill is often a sign that something isn’t working the way it should.

For homeowners in Easton, Emmaus, the Lehigh Valley, and Phillipsburg, summer brings a mix of outdoor watering, higher household demand, and unfortunately, hidden plumbing issues that can quietly waste thousands of gallons of water. The key is knowing what’s normal—and what’s not.

What’s Considered Normal in Summer?

During the summer, most households do use more water. Lawns need watering, gardens are in full swing, and kids are often running through sprinklers or filling small pools. It’s typical to see a moderate increase in your bill during this time.

However, a sharp or unexpected spike—especially if your habits haven’t changed much—usually points to a problem. A small leak or malfunction can easily add hundreds of dollars to your bill over the course of a month.

The Most Common Reasons Your Water Bill Is High

One of the biggest culprits is a hidden leak. Unlike a burst pipe, these leaks aren’t always obvious. A running toilet, for example, can waste hundreds of gallons per day without making much noise. Many homeowners don’t realize there’s an issue until the bill arrives.

Outdoor faucets, also known as hose bibs, are another frequent source of trouble. Over time, they can develop slow drips or leaks at the connection point. Because these are outside, they often go unnoticed for weeks. The same goes for garden hoses that aren’t tightly connected or have small cracks.

Irrigation systems can also drive up water usage quickly. A broken sprinkler head or a line leak underground can waste a significant amount of water every time the system runs. Even a misaligned sprinkler that sprays the sidewalk instead of your lawn can add unnecessary costs.

Inside the home, fixtures like faucets and showerheads may develop slow drips. While a single drip might seem minor, it adds up over time—especially if it’s happening 24/7.

How to Check for a Hidden Leak

If you suspect a problem, there’s a simple way to check. Start by turning off all water in your home—no faucets, no appliances, no irrigation. Then look at your water meter. If the meter is still moving, water is flowing somewhere, which usually means there’s a leak.

Another quick check is your toilet. Add a few drops of food coloring to the tank and wait about 10–15 minutes without flushing. If color appears in the bowl, the toilet is leaking internally and needs repair.

Why Summer Makes These Problems Worse

Warmer temperatures can actually make small plumbing issues more noticeable. Pipes expand slightly in heat, connections loosen, and outdoor fixtures get more use than any other time of year. On top of that, increased demand from neighbors—especially during peak watering hours—can put additional strain on the system.

Because everything is being used more frequently, even minor inefficiencies turn into bigger, more expensive problems.

How to Fix the Problem (and Prevent It)

The first step is identifying the source. Tightening hose connections, replacing worn washers, and repairing running toilets are often quick fixes that make an immediate difference. If you have an irrigation system, it’s worth doing a quick inspection to make sure everything is functioning properly and not wasting water.

For older homes, especially in parts of Easton and Phillipsburg, outdoor faucets and shut-off valves may need to be replaced entirely. These components wear out over time, and replacing them can prevent ongoing leaks and future damage.

If you’re unsure where the problem is—or if the meter test shows water movement you can’t explain—it’s best to have a professional take a look. Hidden leaks inside walls or underground require proper tools and experience to locate and repair.

Don’t Ignore a Sudden Increase

A high summer water bill is more than just an inconvenience—it’s often an early warning sign. Catching the issue quickly can save you money, prevent property damage, and avoid more extensive repairs down the line.

If your bill looks higher than it should, it’s worth taking a closer look now rather than waiting for the problem to get worse.
