FAQs
Can I replace my main water line myself?
No. DIY replacement is risky. Licensed plumbers ensure safe installation and prevent water contamination.
How long does a main water line replacement take?
The timeline depends on pipe length, location, and whether it’s a repair or full water main line replacement. Simple repairs may take a few hours, while full replacements can take longer.
Will you help prevent future issues?
Yes. We inspect, repair, or replace the main water line as needed and provide maintenance guidance to help keep your water system safe.
How frequently should water lines be replaced?
The lifespan of water pipes varies by material. Brass, cast iron, and galvanized steel can last 80–100 years, copper typically lasts 70–80 years, and PVC pipes usually last 24–50 years. In older homes, it’s recommended to verify the pipe material and condition.
What is the difference between a water service line and a main line?
The water main is the primary pipe running along the street. The service line is the underground pipe on your private property that carries water from the main line into your home or business.
