5 Subtle Signs Your Main Water Line Is Leaking Underground

A leaking main water line is one of those problems no homeowner wants to deal with. But it can happen due to root damage, high water pressure, home renovation accidents, and soil shifting. A main water line leak can hike your water bills, cause structural damage, and result in low water pressure. Here are 5 signs of a main water line leak—with guidance from the skilled plumbers Pittsburgh, PA at Neighborhood Plumbing.

Your Water Bill Has Unexpectedly Increased

Your water bill should remain within the same range if your water usage habits haven’t changed. A main water line leak can become evident where there are significant fluctuations in your monthly water bill. Compare your water bills from the previous months and schedule an inspection when you notice a spike. A local plumber repair service can find hidden underground leaks without causing damage to your yard or lawn. Finding hidden leaks early enough can save water, prevent structural damage, and preserve water quality. Moreover, you can determine the condition of your water line and know when to schedule a new water line installation.

Your Water Meter Keeps Running

Reading your water meter is a simple way to tell if you have an underground water leak. Your water meter shouldn’t continue moving when all the water in your home is turned off. If it doesn’t, it is simply telling you one thing: you are losing water somewhere in your plumbing. Here’s how to perform a water meter test to see if your main water line is leaking underground.

• Shut off all water fixtures—toilets, faucets, showers, dishwashers, washing machines, and more.
• Note the meter reading and write it down
• Check the water meter in 2 hours to see if the numbers have changed

If your water meter is still moving after turning off all water, you probably have an underground leak. Reach out to a trusted plumbing service for a professional inspection once you suspect a hidden water leak in your home. The experts will come in with specialized tools such as moisture meters and thermal imaging cameras to find the leak and make repairs.

Soggy Or Muddy Patches

Another red flag is the appearance of soggy or muddy patches on your yard when it has not rained. These signs often appear after the leak has been present for some time and the water is now finding its way onto the surface. Aside from the aesthetic damage, these problems can cause costly damage if the leak is not repaired on time. After some time, you may notice lush patches of grass around the leak area. Do not hesitate to call a top-rated plumbing repair service when you notice soggy patches in your yard. They are a way of your underground plumbing telling you there’s a problem that needs to be investigated.

Water Pressure Gradually Drops

Have you noticed weaker water pressure throughout your home? A damaged main water line may not be able to deliver enough water to your plumbing fixtures.

Unlike clogged faucets or aging fixtures that affect only one area, a main water line leak usually causes reduced pressure throughout the entire house. Showers may feel weaker, outdoor hose bibs may produce less flow, and appliances like washing machines may take longer to fill.

If the pressure decline happens gradually instead of suddenly, an underground leak could be the cause.

You Hear Running Water When Everything Is Off

Your plumbing should be quiet when no fixtures are in use. If you hear the sound of running water, hissing, or a faint rushing noise inside walls or near your home's foundation after every faucet has been turned off, water may be escaping somewhere underground.

A simple way to check is to shut off every water-using fixture and appliance, then listen carefully. If the sound continues, it's time to have your plumbing system evaluated by a skilled plumber.
