Replacing Your Service Water Line

As a homeowner, you will most likely experience problems with the water main to your house at some point – and unfortunately, you will probably have to hire a professional plumber to perform the necessary repairs. When that day comes, here are some things to keep in mind when you’re facing an expensive water line repair or service line replacement.

What Is a Water Main?

A water main is the pipe that delivers clean water to your home from your municipal water utility. The water main connects to your private water service line, which is typically located below ground on your private property. The water service line should not be confused with your private sewer lateral, which transports used wastewater and sewage away from your home.

What Kinds of Water Main Problems Can Occur?

Over time, holes or cracks – caused by corrosion from the soil, moisture, or earthquakes – can develop in a water main pipe.

Water pipes are subject to pressure changes. Eventually, a breach in the water main will result in a water leak that reaches the surface. Depending on where the breach occurs, a leak can manifest on the street, in your yard, or even the basement of your home. A water line break can also allow contaminated water to enter your home. If this this occurs, it is not safe to consume tap water in your home.

Water Shutoff Fixture

Most houses have a shutoff valve that can be used to stop the flow of water from the main in an emergency. In many cases, your public utility will shut off water flow in an emergency. But if not, you can cut off water flow yourself. The homeowner shutoff valve is typically located next to the water meter) and requires a water meter key.

A leaky water shutoff valve can also be a problem. Some types of water valves (such as gate valves) are prone to leaking. It sometimes possible to tighten the packing nut, and this will stop the leak of the water valve. Adding additional washers or replacing old washers can also help stop a leaky valve. However, if you are unable to stop the leak, it’s time to call a professional plumber to replace the valve.

How Do I Detect Leaks in My Plumbing System?

A leak in your water main that goes unnoticed can cause extensive (and expensive) structural damage to your home. Damages may include water spots on flooring and walls, the emergence mildew and mold, and wastewater.

How can you identify a leak in your water main or water service line? Water spots or mildew on floors and walls are sure signs of a problem. Read our detailed list of sewer line problem symptoms here; a few of them apply to water line leaks (Items 8 and 9 in particular).

Leaks often occur in hard to reach places, such as under a slab or buried deep underground – hidden from view until damage eventually becomes visible. The best way to determine if you have a plumbing leak is to turn off all water fixtures and check if your water meter continues to register water flow. Alternatively, you can hire a leak detection specialist to conduct a test.
