Del Mar conditions
Del Mar is a small coastal city that runs its own water system. The City buys untreated water from the San Diego County Water Authority, has it treated at the City of San Diego's Miramar plant and stores it in Del Mar's four reservoirs. The City's report lists average total hardness of 229 ppm, or about 13.4 grains per gallon, and chloramine disinfection. Scale from water that hard builds in valves, cartridges and water heaters, so fresh shutoffs at each fixture are worth including in a repipe.
The City has completed its initial lead service line inventory, linked from its water quality report. That covers service lines, not the pipe inside your walls.
Plumbing permits go through Del Mar Building & Safety Services and can be applied for online through eTRAKiT, with plan review handled by EsGil Corporation for the City. A repipe should be permitted and inspected before walls are closed.
Being on the coast, Del Mar homes face salt air that is hard on exposed valves, hose bibs and fittings. A repipe is a good time to upgrade exterior connections and protect any runs that come through outside walls.
What affects the cost
- Size of the house, number of stories and fixture count
- Slab or raised floor, and attic or crawl space access
- Hillside lots where pipe runs are longer or harder to reach
- PEX or copper
- Finish restoration in tile, plaster or custom work
- Exterior valves and lines upgraded for salt air
- Permit and inspection
