Common Water Main Service Questions

Whether a water main break counts as an emergency plumbing situation or not depends on the extent of the problem. Your municipality will let you know if you need to leave your home, and when it is safe to return. If the problem is in your service line, a local plumber can help you determine if it's an emergency.

Determining if your water main contains lead involves a few steps. First, check the age of your property, as homes built before the 1980s might have lead pipes. Contact your water utility company for information on your service line material. Then, you can hire a professional plumber to conduct an inspection or use a lead testing kit to analyze water from the main line.

While you may have some water, it's best to wait until after the repair is complete to use your home's pipes. For one thing, the water pressure will most likely be greatly reduced, leading to a less-than-intense shower. There's also the risk of contamination from dirt and bacteria that can enter the broken water main pipe. In many cases, a pro will turn off the flow of water from your water main to do the repairs, so showering won’t likely be an option.

PEX is approved for use with main water lines due to its stability and resistance to high water pressure. If you live in a cold climate and are wondering how to unfreeze pipes, it's helpful to know that PEX is less likely to burst in freezing temperatures. You can also insulate your pipes to prevent freezing and protect your PEX piping.

Annual inspections, prompt leak repair, and avoiding tree planting near mains prevent damage, prolonging service life and reliability.
