Main Water Line Repair

The main water line that leads up to your home is under a lot of physical pressure. In the USA, the typical range for water pressure is between 40 and 60 PSI, with 50 being the median. The last thing any property owner wants is a mainline water leak. High-pressure water leaking into your soil can erode it, causing landscaping problems and sinkholes. Sometimes, it can permanently damage the foundation / slab. It can also waste a tremendous amount of water and drive up the utility bill. A professional repair by a qualified plumber is essential to prevent further loss.

Water Line Breakages

A water line break can happen for a variety of reasons, but age and temperature are the usual culprits. When there is little snow and the ground freezes, the contraction puts additional force / pressure on the main water line. If the water inside of the pipe freezes, it adds additional outward pressure. Piping materials slowly degrade over time, and become brittle, which leads to cracks and leaks. Installation problems, natural erosion, and ground settling can all cause mainline water breaks.

Signs / Symptoms of a Water Line Break

1.) A waterlogged lawn is a telltale sign of a water line break. Water continuously pouring out underground can cause sinkholes and soil shifting. Sometimes the leaks are easy to locate because the water will bubble up and puddle just above the leak. 

2.) An unusually high water bill is also a sign of a water line leak. Sometimes leaks are under paved surfaces, planters, boxes, and other obstacles. If the leak drains into the community water table, you might not find out about it until the water bill comes. That water bill can be high depending on how bad the leak is. 

3.) If you can hear hissing and other chatter past the shut-off valve, there’s a good chance you have a line break outside. If the water is not running inside of the building and these noises or gurgling sounds continue, then you probably have a water line break.

4.) Reddish-brown stains in your freshwater could be an indicator of a water line break. Dirt and debris can get into pipes through fractures and line breaks. Next, they show up as discolored water in your sink or shower. 

5.) Low water pressure combined with any of the above symptoms is a red flag that you have a water line break. The low pressure itself doesn’t mean it is a leak, but it should be considered, especially if you have some of the other problems listed above.
