Plumbing in North Texas

Plumbing FAQs for North Texas Homeowners

Why is plumbing so expensive to repair in North Texas?

Several factors drive higher plumbing costs in North Texas. Hard water causes significant mineral buildup that damages pipes and fixtures faster than in soft water regions. Many DFW neighborhoods have aging pipe systems reaching end of life. Slab foundations mean plumbers often must tunnel under or break through concrete to access buried pipes, adding significant labor cost. And the region's strong construction market means licensed plumbers are in high demand.

What is a slab leak and how serious is it?

A slab leak occurs when the water or sewer lines running beneath your concrete foundation develop a leak. They are extremely common in North Texas due to expansive clay soils that cause foundations to shift, stressing underground pipes. Even a small slab leak can waste tens of thousands of gallons per month and damage your foundation and flooring. If you notice your water bill spiking without explanation, or hear running water when everything is off, call a plumber for leak detection promptly.

Should I choose a tankless or traditional water heater in DFW?

Both are viable. Traditional tank water heaters (40–50 gallon) are the most common and have lower upfront cost ($900–$1,600 installed). Tankless units provide unlimited hot water and lower operating costs but cost more upfront ($2,000–$4,500) and require annual descaling in DFW's hard water. Tankless units can also struggle during rare hard freezes if not properly insulated. For most DFW homeowners, tankless makes financial sense if staying in the home 10+ years.

What should I do during a North Texas winter freeze?

Disconnect garden hoses, insulate exposed pipes in garages and attics, open cabinet doors under sinks on exterior walls, and let faucets drip when temperatures drop below 20°F. Know where your main water shutoff is located before a freeze hits — not during one. If a pipe bursts, shut off the main valve immediately and call a licensed plumber. Winter Storm Uri in February 2021 caused billions in plumbing damage across DFW and demonstrated that North Texas pipes are vulnerable to extended hard freezes.

How do I know if my pipes need to be replaced?

Signs that repiping may be needed include persistent low water pressure across multiple fixtures, discolored (rusty or yellowish) water, frequent leaks at multiple locations, pipes that are more than 50 years old, or pipes made of polybutylene (a gray plastic used in many 1970s–1990s DFW homes that is prone to failure). A licensed plumber can assess your pipe condition with a video camera inspection and recommend repair versus repipe.
