Do you serve all of Santa Cruz County?

Yes. We are based in Watsonville and work throughout Santa Cruz County, including Aptos, Capitola, Soquel, Santa Cruz, Scotts Valley and Freedom, plus parts of North Monterey County.

Do you charge for estimates?

Estimates on scheduled work, replacements and remodels are free. For a diagnostic visit on an existing problem there is a trip and diagnostic fee, credited in full toward the repair if you approve the work that day.

Will I know the price before work starts?

Yes. You get a flat price in writing and you approve it before anything begins. No hourly meter, no surprises at the end.

Are you licensed and insured?

Yes. We carry both C-36 plumbing and C-54 tile classifications on our CSLB license. Bonded and insured. You can verify the license on the CSLB website.

Do you handle both the plumbing and the tile on a bathroom remodel?

Yes, and that is unusual. Most homeowners have to hire a plumber and a separate tile contractor. We hold both licenses, so the water lines, the shower pan, the waterproofing and the finished tile are all one person's responsibility.

Water Filtration & Water Quality Testing in Watsonville, CA

Watsonville runs on groundwater in much of the basin, and the mineral content shows up in every glass, every showerhead, and every angle stop in your house. Hard water is not dangerous, but it is hard on your plumbing, your fixtures, and your skin.

JPlumbing installs and services whole-home water filtration systems and water softeners in Watsonville and across Santa Cruz County. We also do water quality testing so you know exactly what is in your water before you spend money treating it.

Licensed. Local. We test first, then recommend the right system.

What Is Actually in Your Water

Before we recommend a filtration system, we test. A water quality test tells you what you are dealing with — hardness, chlorine, iron, manganese, pH, and in some areas, nitrates or other contaminants. The right system depends on what the test shows, and guessing is how people end up with a system that does not solve their actual problem.

Free basic hardness and chlorine test on site, with results in minutes

Comprehensive lab water quality testing for hardness, iron, pH, nitrates and more

A written report of what is in your water and what each result means

System recommendations matched to your actual water, not a one-size pitch

Installation of whole-home filtration, water softeners, and under-sink systems

Ongoing filter replacement and system maintenance

If you are on a private well in Corralitos, Green Valley or Larkin Valley, water testing is even more important. Well water changes with the seasons and the water table, and what was fine last year may not be fine now.

Our Water Filtration Services

Water Quality Testing

We start with a basic on-site test for hardness and chlorine, with results in minutes. For a full picture, we collect a sample for lab analysis covering hardness, iron, manganese, pH, total dissolved solids, and where relevant, nitrates and bacteria. You get a written report and a plain-English explanation of what each number means.

A water test is the only honest starting point. Anyone who recommends a system without testing is selling you a box, not a solution.

Whole-Home Water Filtration

A whole-home system treats every drop that enters the house — the kitchen sink, the showers, the laundry, and the water heater. We size the system to your home and your water, install it at the main, and set it up so filter changes are something you can do yourself or have us handle on a schedule.

Water Softeners

If hardness is the problem, a water softener is the fix. Hard water scales up water heaters, clogs showerheads, leaves spots on everything, and shortens the life of every fixture and appliance it touches. A properly sized softener protects your plumbing investment and pays for itself in fixture and appliance life.

If you are replacing fixtures and water heaters every few years and wondering why, hardness is usually the answer.

Under-Sink and Point-of-Use Filtration

Not every home needs a whole-home system. If your water is fine except for taste or chlorine at the kitchen sink, an under-sink filter or reverse-osmosis unit is a fraction of the cost and solves the drinking water question without treating the lawn.

System Maintenance and Filter Replacement

A filtration system only works if the filters get changed. We set up a maintenance schedule, replace filters, rebed softeners, and test the output so you know the system is still doing its job. A system that has not been serviced in two years is not filtering anything.

Warning signs

Signs You Need a Water Filtration System

Any two of these together usually means a water quality test is worth the call. The test is cheap. The answer is worth knowing before you replace another water heater.

White chalky buildup on faucets, showerheads and glass shower doors

Water heater rumbling or failing early from sediment and scale

Dry skin and hair after showering, or soap that will not lather

Rust or iron stains in toilets, tubs, and on white laundry

A chlorine, sulfur, or metallic taste or smell in your water

Fixtures and angle stops corroding faster than they should

Appliances like dishwashers and washing machines failing early

You are on a private well and have never had the water tested

The signs are usually visible: chalky white buildup on fixtures, dry skin after showering, rust or iron stains, early water heater failure, or a taste or smell you do not like. A water quality test confirms what is actually in your water and tells us whether a system is worth it and which one.
