Water Purification Systems We Install & Service

No two properties have exactly the same water quality concerns, so we work with a range of system types to find the right fit for your home or building.

Here are some of the more common options:

  • Whole-House Filtration: Treats water at the main supply line so every faucet, shower, and appliance receives filtered water, not just one point in the home.
  • Reverse Osmosis Systems: Installed under the kitchen sink as a point-of-use solution, reverse osmosis (RO) systems are designed to reduce dissolved solids, heavy metals, fluoride, nitrates, and other impurities from drinking and cooking water.
  • Water Softeners: Address hard water by targeting the calcium and magnesium minerals that cause scale buildup in pipes, water heaters, dishwashers, and fixtures.
  • UV Water Treatment: Neutralizes bacteria, viruses, and microorganisms without chemicals and pairs well with other filtration methods as part of a layered approach.
  • Activated Carbon Filters: Designed to reduce chlorine, chloramines, sediment, and volatile organic compounds and address the taste and odor issues San Diego tap water is known for.

A professional assessment takes the guesswork out of the decision, and proper installation by a licensed plumber ensures correct sizing, full integration with your existing plumbing, and helps avoid pressure or leak issues once the system is in place.

Why San Diego County Homeowners Choose Our Water Purification Services

Plenty of companies install water purification systems. Plumbing Plus backs every job with the experience, warranties, and customer-first practices that matter long after the installation is done.

The Plumb Star Partner™ Membership Program

Our Plumb Star Partner™ membership is built for homeowners who want ongoing peace of mind, not just a one-time install. Members receive front-of-line priority scheduling for both routine and emergency calls, 10% off all plumbing services, no dispatch fees, free estimates, and an annual safety inspection that covers a water quality test, water pressure check, leak inspection, dye testing of toilets, water meter check, water heater flush, and a sewer camera inspection of one drain. Every job completed while the plan is active is backed by a one-year workmanship and materials warranty, an upgrade over our already strong standard coverage.

Transparent Pricing & Free Estimates

Before any work begins, we provide a detailed written estimate that reflects the full scope of the job. What we quote is what you pay: no hidden fees, no surprises when the invoice arrives. Standard customers also receive our workmanship and materials warranty on every service.

Financing, Availability & Customer Experience

Water purification isn’t always a planned expense. We’ve partnered with Service Finance to offer flexible financing: short-term options with low interest or longer term plans with lower monthly payments, so an upgrade doesn’t have to wait for the right budget moment. We’re also available 24/7 for urgent water-related needs. When a technician is on the way, you’ll receive an automated text 30 minutes before arrival with their name and details. Payment is collected by tablet at the job site, and photos of completed work are sent with your digital invoice immediately upon completion. If you’re not completely satisfied, we’ll make it right.

San Diego County’s Hard Water Problem

San Diego’s drinking water averages about 16 grains per gallon (roughly 276 ppm), which the U.S. Geological Survey classifies as “very hard.” That water travels long distances from sources like the Colorado River and Northern California, picking up dissolved calcium and magnesium along the way. The result is scale buildup inside pipes, water heaters, and appliances that reduces efficiency and can shorten service life. The long-distance transport also means the water is treated with chlorine and chloramines, which can affect taste and odor at the tap.

San Diego County’s arid climate means reliance on imported water isn’t going away. The City publishes annual Drinking Water Quality Reports with detailed hardness levels and contaminant measurements. It's worth reviewing if you want the full picture. A properly installed water purification system can address these conditions at the source, before the water reaches your faucets or flows through your appliances.

San Diego Water Purification FAQs

How Do I Know Which Water Purification System Is Right for My Property?

It depends on the specific water quality issues you’re dealing with: hard water, chlorine taste, dissolved contaminants, or a combination. A professional assessment helps identify which system type, or combination of systems, is most suitable for your home or building. We can walk you through the options before any work is recommended.

Does Plumbing Plus Install Water Purification Systems for Commercial Properties?

Yes. We serve residential homeowners and commercial and property management clients throughout San Diego County. Whether you’re managing a single property or multiple units, our team handles installation and ongoing service for both.

How Often Does a Water Purification System Need Maintenance?

Most filters benefit from replacement every six months to a year, though the right schedule depends on your system type, water usage, and local water quality. Annual maintenance typically includes filter or media replacement, pressure checks, and a performance review. Plumb Star Partner™ members receive this as part of their annual safety inspection at no additional visit cost.

      "Would recommend. 10/10"
      Amazing service! David and Cole replaced my old faulty water heater on the same day I called. Service was fast and thorough. Both David and Cole were friendly and helpful in making everything work, so I could get my hot water today and didn't have to wait. Great communication and response time. David and Cole were respectful of property, considerate of the neighbors, and were nice to my cat, too. Would recommend. 10/10

      "We Highly Recommend Their Services!"
      It was a pleasure working with our plumber Martin. He went over and above what needed to be done and had a great attitude. This was not an easy fix and he made it work, with a smile on his face! Our customer service agent Kyle was so easy to work with and helped us to feel at ease. We highly recommend their services!

      Great company! Plumbing Plus saved the day for us a number of times over the years. Always speedy-quick response and expert work. Courteous, clean, conscientious. We've been spoiled by Jason's attention to our most recent plumbing needs, he's amazing! But the whole team has been great. Great communication, documentation, results. We highly recommend it!

      "Great Job!"
      Great service from Martin Ruiz of Plumbing Plus. We had a leak in the water pipe coming into our house and he quickly diagnosed it. He had some issues getting the parts but stuck with it and found them downtown. Once he had the parts he quickly fixed the problem. Great job!

    Join Our Plumbing Plus VIP Program

    Plumb Star Partner™ Membership

    There’s a difference between calling a plumber when something breaks and having a plumber who already knows your home. Our Plumb Star Partner™ membership is built around that idea. 

    Members receive front-of-line priority scheduling for both routine and emergency calls, 10% off all plumbing services, no dispatch fees, and free estimates. Once a year, we perform a comprehensive safety inspection: a water quality test, water pressure check, leak inspection, dye testing of toilets, water meter check, water heater flush, and a sewer camera inspection of one drain. All work completed while the plan is active is backed by a one-year workmanship and materials warranty, an upgrade over our standard terms.

    That combination of priority access, annual inspection, and an enhanced warranty isn’t something a standard service call delivers. It’s designed for homeowners and property managers who’d rather stay ahead of a problem than respond to one. If you’ve had a plumbing emergency before, you already know the math. Joining the Plumb Star Partner™ program is one way to change the equation going forward.

    If want to learn more about the Plumb Star Partner™ membership, we’re ready to help. Call Plumbing Plus today at (858) 630-3141 and let’s get started.
