Common Causes of Leaks and How to Detect Them in Olympia

Water leaks are often hidden, causing structural damage over time and spiking your monthly bills. While you need a professional to accurately diagnose and repair a leak, there are common causes you can watch out for that can tell you it’s time to schedule service. Here’s what you need to know about leak detection in Olympia, WA.


Signs You Might Have a Leak

In Washington, water leaks tend to follow certain patterns. These are some of the most common signs that you may have an active plumbing problem.


High Water Bills

Is your monthly water bill higher than normal, even though you haven’t changed your usage? If so, there’s a good chance you have a hidden leak.


Musty Odors and Mold Growth

Leaks often cause moisture between and inside walls. This creates the ideal environment for mold and mildew to thrive. While you can’t always see this mold growth, you can often smell the persistent dampness that points to a potential leak.


Sounds of Running Water

Hearing a faint hissing or trickling noise even when your faucets are completely turned off can be another sign. If you suspect you hear running water when you shouldn’t, it’s a good idea to reach out to a professional.


Checking for Leaks

Aside from noticing these signs, you can also conduct some simple leak detection in Olympia, WA, by checking your home’s main water meter. Start by turning off everything in your home that uses water, like faucets and any appliances. Check your water meter box; if the dial is spinning, water could be escaping somewhere in your system.


Even if it isn’t moving, write down the numbers on the display. Leave everything off and check it again after several minutes have passed. If any of your original numbers change, you may have an active leak.


Tracking this can also be beneficial when you call a plumber, as it gives them a general idea of the extent of a leak beforehand.
