What Is a Water Main and Why Is It So Critical?
Your home or business relies on a main water line to deliver clean water from the city supply into your property. It runs underground and connects to every plumbing fixture inside. When it malfunctions, whether from age, freezing, root intrusion, or corrosion, you’re left with low water pressure, discolored water, or even complete service loss. Fast and professional repair is crucial to restoring your home’s water supply and preventing major damage.
What Are the Signs You Need Water Main Repair?
Water main issues often develop out of sight, which is why early detection is critical. Be on the lookout for these signs:
- Sudden drop in water pressure throughout the house
- Unexplained increase in your water bill
- Discolored or rusty water coming from faucets
- Soggy, wet patches in your lawn or driveway
- Sounds of running water when pipes aren’t in use
- Water pooling around the foundation or in crawl spaces
If you notice any of these symptoms, call Sapphire Plumbing immediately. Our licensed technicians use electronic leak detection and pressure testing equipment to identify issues with pinpoint accuracy, without unnecessary digging.

What Causes Water Main Failures in Plano, TX?
There are several common reasons your main water line might fail:
- Aging pipes: Galvanized or clay pipes degrade over time and are prone to cracks and corrosion.
- Tree root intrusion: Roots from nearby trees can infiltrate your pipe joints, causing major blockages or breaks.
- Ground shifting: Soil expansion or erosion due to heavy rain or drought can shift and crack pipes.
- Temperature changes: Freezing or extreme heat may expand or contract pipes beyond their limit.
- Poor installation: Subpar work from unlicensed contractors often leads to early failures or code violations.
Our experienced plumbers not only fix the damage but also prevent future problems by using modern materials and proper installation techniques.
