San Mateo Plumbing Basics
One local issue worth understanding is the private sewer lateral that connects a property to the public sewer main. In San Mateo, the owner is responsible for this line, and inspections or permits may be required in certain situations.
-
Private Lateral Responsibility.
The property owner maintains the line from the building to the public sewer main, including the connection to the main. -
When an Inspection May Be Required.
The City requires an inspection in certain situations, including a property sale, qualifying remodeling projects, and some commercial or multifamily overflow events. -
Permits for Repair or Replacement.
Work on private property may require a building permit, while work in the public right-of-way requires an encroachment permit.
If you’re dealing with recurring backups, planning a repair, or need to understand the condition of the line, we can inspect it with a sewer camera and explain what we find.

Recent Plumbing Work in San Mateo
See two recent San Mateo plumbing projects: a water heater repair and a main sewer line replacement.
-
Water Heater Repair
Problem – the gas control valve and burner assembly had begun to fail from normal wear.
Work – we shut off the water and gas, drained the tank, replaced the necessary components, and reassembled the system.
Result – the water heater was refilled and tested for safe ignition and proper operation.
-
Main Sewer Line Replacement
Problem – an underground sewer line was leaking and heavily affected by root intrusion, making proper drain cleaning and maintenance impossible.
Work – we removed the damaged sections, installed new ABS sewer piping and cleanouts, and connected the new line with approved transition couplings.
Result – the sewer line was rebuilt with proper access for future maintenance, and the completed work included a 10-year warranty.
