Since 1968, Pinellas County residents have relied on McGill Plumbing & Water Treatment, Inc. to solve hard water, sediment, and taste issues. Based at our landmark Largo location on Missouri Avenue, our family-owned, A+ BBB-rated company provides tailored water conditioning and purification solutions to homes and businesses throughout the community.

Water Softener Installation and Service for Hard Water in Pinellas County
Hard municipal water is a widespread problem throughout Pinellas County, causing stubborn scale buildup and shortening the lifespan of water heaters and appliances. We install FLECK 5600 Demand Water Softeners—proven, salt-based ion-exchange systems that extract calcium and magnesium minerals before water flows through your pipes and fixtures.
Installing a water softener requires a direct tie-in to your main water line, which must be performed by a licensed plumber to ensure code compliance and leak-free operation. Every new installation includes our 1-year parts and labor warranty, backed by the manufacturer's coverage for the FLECK unit. For homeowners interested in salt-free conditioning, our plumbers can discuss alternative options during your consultation.
Water Filtration Systems for Pinellas County Homes
While water softeners focus on mineral hardness, water filtration targets chlorine odors, foul tastes, discolored sediment, and chemical contaminants. McGill Plumbing installs both point-of-use and whole-home filtration systems:
Everpure Point-of-Use Filtration: Under-sink Everpure systems filter drinking and cooking water directly at the tap, removing chlorine, bad tastes, and cloudiness.
Whole-Home Water Filtration: Whole-home systems filter municipal water as it enters your house, protecting every faucet, showerhead, and appliance from rust, sediment, and chemical odors.
Pairing a FLECK water softener with an Everpure filtration system provides complete water conditioning by removing hardness minerals while purifying your tap water.
Signs Your Pinellas County Home Could Benefit from Water Treatment
You can easily spot water quality issues through daily observation. Scheduling an evaluation with a licensed plumber helps identify the right solution.
Persistent Scale Buildup
White or yellowish crust around faucets and showerheads indicates heavy mineral buildup from hard water that requires a softener.
Soap That Fails to Lather
Hard water minerals prevent soap and shampoo from lathering easily, leaving a slick film on your skin and dishes.
Unpleasant Tastes or Odors
Chlorine, sulfur, or metallic tastes or odors indicate a need for filtration rather than hardness alone.
Cloudy or Discolored Water
Visible rust or sediment traveling through your pipes indicates a need for a whole-home filter.
Dry Skin and Brittle Hair
Hard water strips away natural moisture, an issue that improves noticeably after installing a water softener.

Frequently Asked Questions About Water Treatment
Common signs include mineral crust around fixtures, spots on clean dishes, and soap residue that will not rinse clean. Pinellas County water naturally contains high mineral levels, so hard water is very common here. An on-site evaluation gives you an exact answer.
A water softener removes hardness minerals like calcium and magnesium through ion exchange. A water filtration system removes chemical contaminants, sediment, chlorine, and foul odors that softeners cannot filter out.
We install FLECK 5600 Demand Water Softeners for hard water and Everpure systems for point-of-use drinking water filtration. Both are industry-leading systems, and you can see working models at our Largo showroom.
Yes, we provide a 1-year parts and labor warranty on new water treatment installations, supported by additional manufacturer warranties on FLECK softeners. Water treatment repair work carries a 90-day warranty.
Water softeners tie directly into your main water line, requiring live pipe connections, proper bypass valves, and code-compliant drain lines. A licensed plumber installs everything safely to protect your property and prevent leaks.
Yes, hard water scale builds up inside supply lines, fixtures, and water heaters over time. This buildup reduces water pressure, lowers water heater efficiency, and forces appliances to fail early. Installing a softener protects your plumbing investment.

Hear From Our Happy Customers
McGill Plumbing and Water Treatment is a business with 3 generations of satisfied customers. Cody and Johnny were professional, knowledgeable and friendly. Highly recommend for any plumbing issues you may have.
I've been using McGill for nearly 20 years. It started with a stupid mistake that broke an outdoor faucet on a weekend and McGill was out quickly to fix the problem. Over the years they have replaced toilets and fixed other plumbing leaks, and are responsive. There's a reason they have been around so long! And Tonya is always great to work with, as well as the other employees I have encountered.
I am extremely happy with McGill Plumbing. They moved my plumbing from the floor to the attic. Jake and Bobby were professional, friendly, explained what they were doing, and very easy to work with. Kudos to McGill Plumbing. Reasonable price. Everything was upfront. No surprises. I would highly recommend.
Just an incredibly professional job installing my hot water heater by Mark. Old piping was a mess and he cleaned it all up with sweated(soldered) copper pipes! Same price or cheaper than the competition and they don’t solder copper. Can’t be happier.
I called McGill plumbing to fix a plumbing issue I was having. They scheduled someone to come to my house within 30 minutes. Chris from McGill addressed the problem and fixed it for me. He was very professional and kind.. I will continue to use McGill if I have anymore problems in the future.
