Expert Water Quality Testing in San Diego, CA

San Diego tap water is sourced from the Colorado River and Northern California, traveling hundreds of miles before reaching your tap. By the time it arrives, it carries measurable levels of hardness, disinfection byproducts, and other contaminants that a standard city report may not flag as concerns. Water quality testing from Every Day Water Heaters gives you a clear picture of what is actually in your home's water. We test for hardness, total dissolved solids, chloramines, disinfection byproducts, and other key indicators specific to San Diego's water profile. San Diego's water averages around 16 grains per gallon, which qualifies as very hard, and TDS levels have been measured above the EPA's secondary guideline of 500 ppm. Older homes across the city may also see trace metals from aging interior plumbing that city-level reports do not capture. Once we have your results, we walk you through what they mean and which filtration or treatment options fit your home. Call us to schedule your water quality test today.

Water Quality Testing FAQ

Common questions about water quality testing in San Diego, CA.

City-level compliance does not tell you what is happening at your specific tap in San Diego. Older interior plumbing, local pipe conditions, and hardness levels that vary by neighborhood can all affect your water in ways a city report does not capture.

We test for hardness, total dissolved solids, chloramines, disinfection byproducts, and other contaminants relevant to San Diego's water supply. Results give you a home-specific picture rather than a city-wide average.

San Diego's water averages around 16 grains per gallon, which is classified as very hard, and that mineral load builds up as scale inside your water heater. Scale insulates the heating element, raises energy use, and shortens the unit's working life.

Yes, testing your water first tells us exactly which contaminants are present in your San Diego home. That data points to the right filtration solution instead of installing a system that may not address your actual water issues.

No, many San Diego homeowners test their water even when it looks and tastes fine. Contaminants like disinfection byproducts and elevated TDS often have no visible signs but can still affect appliances and long-term water quality.

Yes, we provide water quality testing throughout San Diego. Contact us to schedule a visit and get results specific to your home's water supply.

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.

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.
