Plumbing in Santee, CA

Santee grew quickly from the 1960s onward, so most of its houses belong to a few eras of tract building along the San Diego River valley, with newer neighborhoods filling in the edges. That makes the plumbing more predictable than in an older town: within a neighborhood, many houses were plumbed the same way at the same time, and they tend to wear out in the same order.

The Houses and Their Plumbing

Homes from the 1960s and 1970s usually have copper supply lines, often in thin-walled pipe, and many are built on slabs. After decades of San Diego County’s hard water, that copper starts to develop pinhole leaks, frequently on the hot-water side and frequently under the floor. Drains from the 1970s onward are more often ABS than cast iron, which holds up well, but the original shutoff valves, supply lines and fixtures are now well past their best.

Many of these houses also have a pressure regulator where the water line enters, and a regulator that has failed lets street pressure into the house. High pressure shows up as banging pipes, running toilets and a water heater relief valve that drips. When a regulator or a check valve closes the system, thermal expansion from the water heater needs somewhere to go, and an expansion tank is the usual fix.

Newer neighborhoods at the edges of town are usually plumbed in PEX or newer copper with plastic drains, and their trouble tends to be fixtures, water heaters and the odd fitting rather than worn-out pipe. The older streets closer to the middle of town are where re-pipes and slab leak repairs come up.

Work Santee Homes Tend to Need

• Finding and repairing slab leaks and pinhole leaks in older copper, or re-piping when they keep coming back.
• Replacing failed pressure regulators and correcting thermal expansion with an expansion tank.
• Water heater replacement, tank or tankless, as the original units and their first replacements age out.
• New fixtures and supply lines for kitchen and bath remodels.
• Swapping stiff, crusted shutoff valves for quarter-turn valves.
