The City of Del Mar supplies its own residents, buying untreated water from the San Diego County Water Authority, having it treated at the City of San Diego's Miramar plant and storing it in four city reservoirs. No household well pump is involved, so a pressure problem in a Del Mar home is usually a regulator, a private line leak, a booster pump or scale. Call the number on this page to be connected with a local plumber in Del Mar.

What you may notice
- Every fixture weaker than it used to be
- Banging pipes when a valve closes, or a dripping relief valve on the water heater
- One shower or faucet slow while the others are normal
- A booster pump in the garage that clicks, hums or runs too long
- Crusted or weeping valves outdoors
Banging and dripping relief valves usually mean pressure is too high, not too low, and the regulator is the first thing to check.
Del Mar's water and conditions
Del Mar is a small coastal city whose Public Works department runs the water system. The water is chloraminated and hard: the City's report gives an average of 229 ppm, or about 13.4 grains per gallon, within a range of roughly 10.1 to 14.5. That scale accumulates in regulator ports, cartridges and aerators, so a gradual loss of pressure at several fixtures can be mineral buildup rather than a failing part.
Salt air near the beach and lagoons corrodes exposed fittings, valve handles and the electrical parts of any outdoor pump. Homes on hillside lots sometimes use a booster pump, which has a switch, check valve and often a small tank that wear the same way well equipment does.
For a problem in the City's system, Public Works is at (858) 755-3294, and after hours the City lists North County Dispatch at 858-756-1126.
What affects the cost
- Which part failed: regulator, booster pump, tank, valve or pipe
- Corrosion that has spread beyond the obvious fitting
- Access around hardscape, retaining walls and tight lots
- A plumbing permit from Del Mar Building & Safety Services, which accepts applications online through eTRAKiT
When you call
This line connects you with a free referral service, not a plumbing company. An independent local plumber who works in Del Mar will ask whether pressure is too low or too high, whether every fixture is affected, and whether there's a booster pump or softener on the property. Knowing where your main shutoff and regulator are helps the visit go quickly, and a note of when the problem started and whether it comes and goes is useful too.
