Higher bill than usual?

A high water bill can catch you by surprise, and you'll no doubt be wondering what could have caused the spike. Here are some of the common causes for a higher-than-usual bill and what you can do to rule in and out possible causes.

Steps for troubleshooting a high bill

It’s common to assume that a high bill means a possible leak on your property, but before you investigate that, start by asking these questions.

Step 1: Is the meter-read accurate?
Step 2: Is this a catch-up bill?
Step 3: Has your water usage changed?
Step 4: Check for a leak
