Your home’s main water line carries water from the municipal water supply into your house, and it’s responsible for delivering water to all of your appliances, fixtures, and faucets. However, as with other plumbing systems, your main water line can eventually wear out or break down over time. Ignoring these issues can lead to costly repairs and water damage. Therefore, it’s crucial to be aware of the signs that indicate your home needs a main water line repair.

Low Water Pressure

One of the most common signs of main water line issues is low water pressure. If you notice a lack of pressure in your plumbing fixtures, it could be due to a blockage or leak in your main water line. Poor water pressure can also indicate mineral buildup on the pipes, which can lead to further damage.

Rusty Water

Rusty water is not only unpleasant visually but also indicates that your water lines need repair. If you notice a rust-colored tint to your tap water, it’s a sign of a corroding main water line that’s leaching rust into your water supply.

Water Puddles in the Lawn

If you notice a pool of water in your lawn or areas of your yard that tend to stay damp, it could indicate a broken main water line that’s leaking water underground. This problem should be addressed immediately to prevent further damage.

Increased Water Bills

Another sign of a potential main water line problem is an increase in your monthly water bill. If your monthly water bill is higher than usual, and there’s no identifiable reason behind it, it could indicate a leak in your main water line, causing an increase in water usage and thus an increase in your bill.

Unpleasant Odor

A stinky smell coming from your water faucet is an indicator of a problem in your main water line. The odor could be a result of decomposing organic materials inside the pipes caused by cracks or leaks.


Your home’s main water line is a crucial piece of plumbing, and it is essential to keep it in its best working condition. Addressing these signs early will save you from water damage, costly repairs, and disruptions to your daily routine. If you notice any of these signs, call a professional plumbing service like S3 Plumbing to assess the problem and repair it as soon as possible. These repairs may seem costly upfront, but they’ll ultimately save you from further issues, maintain your peace of mind, and guarantee a safe and steady water supply in your home.
