A whole-house repipe requires a permit from the San Mateo Building Division. As a contractor with an active CSLB license, I handle pulling that permit, scheduling inspections, and ensuring the work meets all current code. My job is to manage that red tape seamlessly so the process is straightforward for you, and the work is documented for your home's records.

Hetch Hetchy provides very soft water, which is excellent for drinking but is slightly corrosive to certain metals. Without protective mineral scale, the water can accelerate the deterioration of anode rods in water heaters and cause premature failure of brass fittings. We recommend inspecting and replacing anode rods more frequently than in areas with hard water.

While our lows rarely hit freezing, the winter rainy season peak brings its own issue. A pro-tip is to clear your roof gutters and extend downspouts at least five feet from your foundation before the heavy rains. This prevents water from saturating the soil around your main sewer line, which is a common cause of backups when the ground is overloaded.

The galvanized steel pipes installed in 1964 are now 62 years old. This material has a functional lifespan of about 50-60 years. In Baywood-Aragon, we are now routinely seeing the final stage of failure: widespread pinhole leaks and total internal blockage from rust scale. What starts as low water pressure in one fixture often indicates the entire home's piping is nearing the end of its service life.

The coastal terrain and gentle slopes around areas like Central Park can stress underground pipes. A lateral line running down a slope may develop low spots where debris collects, leading to repeat clogs. Conversely, a main line running uphill from the street can put extra stress on joints and increase the risk of separation over time, especially with older clay or cast iron pipes.

My typical dispatch route from the Baywood-Aragon area involves heading past Central Park to the US-101 on-ramp. Using the freeway, I can reach most neighborhoods in the city within 30 minutes, and surrounding areas within 45. I keep a truck stocked for the common local callouts, so that response time includes having the right parts on hand.

In this suburban setting, the most common municipal-related issues involve the lateral line from your house to the street main. Tree roots from our mature neighborhoods are drawn to the moisture in older pipe joints. A slow drain in multiple fixtures often signals root intrusion in the lateral. Municipal water pressure here is generally consistent, but a sudden, significant change warrants checking your pressure regulator.

Galvanized steel corrodes from the inside out. After six decades, the pipe's interior diameter shrinks dramatically from rust and mineral scale buildup, a process called calcification. This severely restricts flow, causing the low pressure you're noticing. Often, tapping the pipe reveals a hollow sound where the wall is thin, soon to become a leak.
