Expert Reverse Osmosis System Installation in San Diego, CA

San Diego tap water is legally compliant, but it carries real challenges. The city's water supply draws from the Colorado River and the State Water Project, both known for high mineral loads. By the time water reaches your kitchen, it often measures 500 to 800 parts per million in total dissolved solids. San Diego also uses chloramine as a disinfectant, which standard carbon pitcher filters cannot remove. A reverse osmosis system works by forcing water through a semipermeable membrane with pores so small that dissolved salts, chloramine, heavy metals, and other contaminants cannot pass through. Every Day Water Heaters installs multi-stage under-sink RO systems that connect to your cold water supply, route filtered water to a dedicated faucet, and store treated water in a pressurized tank under the cabinet. We assess your under-sink space, make the cold water and drain connections, mount the filter housing and tank, and flush the system before handing it over. If your countertop is granite or quartz, we handle the faucet hole carefully to avoid cracking. Call us to schedule your San Diego installation.

Reverse Osmosis System Installation FAQ

Common questions about reverse osmosis system installation in San Diego, CA.

San Diego tap water meets federal legal standards, but testing shows contaminants like PFAS, chloramine, and disinfection byproducts that exceed stricter health guidelines. An RO system filters what municipal treatment leaves behind.

The system mounts under your kitchen sink, connecting to the cold water supply line and the drain pipe. A separate dedicated faucet is installed on your countertop or sink deck for filtered water.

Yes. San Diego water is rated very hard at around 16 grains per gallon, and an RO membrane is specifically designed to strip out dissolved minerals, salts, and hardness compounds.

San Diego's high TDS load can clog pre-filters faster than average, so filter cartridges typically need attention more frequently than in lower-TDS cities. Your installer can walk you through a maintenance schedule matched to local water conditions.

Yes. Granite and quartz countertops require careful drilling to avoid cracking, and our team handles that step as part of the installation in San Diego homes.

In many cases, yes. The connection depends on the distance between the RO unit and the refrigerator, and our team evaluates your kitchen layout before making that connection.

Erik did an outstanding job from start to finish. He was methodical, transparent, and priced everything out clearly after I reached out to several companies on Yelp. What really stood out is that you deal directly with Erik the entire time, not a chatbot or a rotating sales team. He walked me through the options, answered every question, and the installation was clean and professional. Exactly what you want when replacing a water heater. I would absolutely recommend Erik and Everyday Water Heaters to friends and family.

Erik was excellent to work with. Communication was easy, pricing was reasonable, and the finished quality of the new water heater installation looks great. Would highly recommend.

Aaron Warner Google review · June 2026

I had a few plumbers come in to look at my tankless heater that was leaking. Each one wanted to charge me a "diagnostic fee". Then Erik came and presented us with some options. We decided to go with a tankless water heater replacement. Erik returned two days later to replace our water heater up to City code. He is friendly and professional. I give him 5 stars for his service. I highly recommend Erik for your plumbing needs. See before and after pictures.

Best service I could have ask for. Fast and honest! He help with my water pressure regulator and my temperature relief valve with the water heater. Definitely keeping his contact 👏🏼

Patricia Guillen Google review · May 2026

Erik is fantastic. He gave me a fair, transparent quote with no hidden fees and installed our new water heater on a Saturday so we didn't have to go without hot water. The workmanship is top-notch, and he even included a better labor warranty than the other big plumbing companies. 10/10 service.
