A water main is the primary underground pipe that delivers water from the municipal supply to your home. Signs that it may need repair or replacement include a significant drop in water pressure, discolored water, water pooling in your yard, or an unexplained increase in your water bill, which could indicate a leak.

Water main damage can be caused by a variety of factors including natural wear and tear, corrosion, ground movement or settling, temperature fluctuations leading to pipe expansion or contraction, tree root intrusion, or accidental damage during other underground work.

The method of repair or replacement will depend on the severity and location of the damage. Minor leaks might be repaired by patching, whereas significant damage or old, corroded pipes usually require complete replacement. Traditional replacement involves excavating to access the pipe, while trenchless methods can replace pipes with minimal digging.

The duration of a water main repair or replacement can range from a few hours to several days, depending on the complexity of the job. Water supply to your home will be temporarily shut off during the repair or replacement process, so it’s essential to coordinate with the service provider to prepare for this outage. They should be able to give you an estimated timeline and any preparations you should make.
