Repiping a House
Repiping a house means replacing outdated or failing plumbing systems with new water, drain, or gas piping. Homes with recurring slab leaks, corroded copper, galvanized water lines, cracked clay sewer pipes, or aging gas lines often require a full system upgrade to restore safety and reliability.
What Repiping a House Includes
Water Line Repiping
This replaces all hot and cold pressurized water lines throughout the home. Materials typically include PEX or Type L copper depending on homeowner preference and layout.
- PEX repipe installation
- Copper repipe installation
- Main water line upgrades
- Fixture reconnections
- Pressure testing of entire system
Drain Line Repiping
Drain repiping replaces failing cast iron, clay, or damaged ABS systems. This restores proper drainage and eliminates recurring backups.
- Cast iron drain replacement
- Clay sewer pipe replacement
- ABS or PVC drain systems
- Sewer lateral upgrades using SDR35 where required
Gas Line Repiping
Gas repiping replaces aging or undersized gas piping to ensure safe fuel delivery.
- Black iron gas pipe replacement
- Polyethylene gas piping for underground exterior lines
- Proper pipe sizing for appliances
- System pressure testing
When Repiping a House Is Necessary
- Multiple slab leaks
- Frequent pinhole copper leaks
- Low water pressure
- Recurring sewer backups
- Failed gas pressure tests
- Major remodeling projects
If plumbing failures occur in different areas of the home, replacing the entire system may prevent ongoing repair costs.
The Repiping Process
- Full plumbing system evaluation
- Clear written scope of work
- Installation of new approved piping materials
- Pressure and flow testing
- Final system verification
All installations are completed according to California plumbing code standards.
