Coronado's water service is provided under a City contract with California American Water, which buys fully treated surface water from the City of San Diego, and there's no indication of well use on the island. So a Coronado pressure problem is almost always a regulator, a corroded line, a leak or a booster pump rather than a well. Call the number on this page to be connected with a local plumber in Coronado.
Coronado is a historic resort city on a tied island, with a strong Navy presence and expensive homes from the Village to the Coronado Cays. Water comes from the City of San Diego's Alvarado and Otay plants by way of Cal Am, and salt air works on every piece of exposed plumbing here. Older homes may also have supply piping that has narrowed with age, which can feel like a weak pump even though the house has none. Larger properties sometimes add a booster pump for upper floors, irrigation or a pool, and that equipment is the owner's to maintain.
What to do now
- Check more than one fixture. A single weak tap points to that tap's aerator or cartridge.
- Ask a neighbor whether they have the same problem. If they do, call California American Water at (888) 237-1333.
- Look at the regulator and any outdoor valves for crust, drips or corrosion.
- If a booster pump is cycling or tripping its breaker, shut it off at the panel.
- Check for wet spots in the yard or water near the meter box.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Whole house weak | Regulator failure or a customer-side leak |
| Sudden high pressure, banging | Regulator stuck open |
| Pump short-cycles | Booster tank lost its air charge |
| Green crust on valves | Salt air corrosion |
| Single fixture slow | Hard water scale |
What affects cost
- Regulator, valve, booster pump, tank or pipe repair
- Corrosion damage that extends past the obvious part
- Access in tight lots, finished garages or under hardscape
- Permits through the City of Coronado Building Services Division, which issues some permits over the counter by email
- Backflow requirements if irrigation or fire sprinklers are involved
Hardness at the City of San Diego source plants runs about 145 to 280 ppm (8.5 to 16.4 grains per gallon), which slowly clogs small ports in valves and switches. Cal Am also requires approved backflow devices on irrigation and fire sprinkler systems at the service connection directly behind the meter, tested every year. When you call this number, you reach a referral service, not a plumbing company, and you'll be connected with an independent plumber who works in Coronado.
