Coway Rentals in San Diego
Covers rental installation and product selection across San Diego. At 276 mg/L, it's the hardest water in Southern California.
Major Cities
- San Diego
- Chula Vista
Local Rental & Installation Notes
Because of the high hardness, scale buildup is common, so we recommend pairing a purifier with a softener — most households need both stages.
Before You Install
A drinking-water purifier and a whole-house softener serve different purposes. Check that you have enough installation space for both.
Q. In San Diego, should I choose a purifier or a softener?
A. Choose a purifier if drinking water quality is your priority, and a softener if scale buildup on household water bothers you. Many households end up needing both.
Actual installation and maintenance service can vary by address, product, and on-site conditions.
Coway Rentals in Northern California
Covers serviceable areas and product selection in San Francisco and San Jose. At 62 mg/L, this is the softest water in the state.
Major Cities

Soft water with low mineral content — here, the main goal is usually improving the taste and smell from chloramine disinfection.
Before You Install
Check your building's rules for product installation and your available kitchen space.
Q. Can I apply for a rental for an apartment in San Francisco?
A. You can apply, but final installation depends on your address and your building's and product's requirements.

California Tap Water: How Does It Differ by Region?
According to official water quality reports from major California water agencies, tap water meets federal and state drinking water standards. However, hardness (mineral content) varies significantly by water source, and most areas disinfect with chloramine.
USGS scale: 0–60 soft, 61–120 moderate, 121–180 hard, 181+ very hard. 1 gpg ≈ 17.1 mg/L.

Scale and White Spots
In high-hardness SoCal, white scale builds up easily on kettles, dishes, and shower doors. Water agencies note that hardness is not harmful to health.
Chloramine Taste and Odor
Most areas use chloramine as the disinfectant. It's used within safety standards, but some households are sensitive to taste and odor.
The Role of Reverse Osmosis
LADWP cites reverse osmosis filtration and ion exchange as ways to reduce minerals in water. Filter configurations and certifications by model are available during consultation.
Figures above are system averages published by each water agency; actual home water quality may vary by utility, season, and building plumbing. Check your local utility's annual water quality report for exact figures.

Is California tap water safe to drink as is?

What works best in hard-water areas like San Diego?
Use a purifier for drinking water; if scale on showers and fixtures bothers you, consider adding a softener. View Coway Water Softeners
