Fresno County

9 cities

Fresno, CA

Fresno County

Homeowners across Fresno research water filtration for a range of reasons — from chlorine taste at the tap to scale buildup on fixtures and appliances. As the largest city in the Central Valley, Fresno's water conditions can vary by neighborhood, water source, and the age and plumbing of individual properties. Generation H2O tests your water at the property before recommending any treatment solution.

Clovis, CA

Fresno County

Clovis homeowners often notice the same regional water patterns as nearby Fresno — chlorine at the tap, hard water scale, and spots on glassware — but conditions still vary street to street and home to home. Because Clovis shares the broader Central Valley water context while maintaining its own utility service, the only reliable way to know what is in your water is to test it at the tap. Generation H2O provides free on-site water testing throughout Clovis.

Sanger, CA

Fresno County

Sanger is a close-knit Central Valley community where homeowners often deal with the region's signature hard water and chlorine concerns, but on a smaller local water system than nearby Fresno. Because smaller systems and older neighborhood plumbing can produce conditions that vary home to home, a test at your own tap is the most reliable starting point. Generation H2O offers free on-site water testing throughout Sanger.

Selma, CA

Fresno County

Selma homeowners sit in the heart of the Central Valley's agricultural belt, where regional water sources and local infrastructure shape what comes out of the tap. Hard water, chlorine taste, and sediment are common concerns here, but every property is different — and agricultural-area water can carry its own variables depending on source and season. Generation H2O tests your water at the property before recommending any treatment solution.

Madera, CA

Madera County

Madera sits in its own county with its own municipal water system, and homeowners here frequently ask about hard water, chlorine taste, and sediment — concerns common across the Central Valley but shaped by Madera's specific water source and local infrastructure. Because Madera draws from its own supply, conditions at your tap may differ from what neighbors in Fresno or Clovis experience. Generation H2O tests your water on-site before recommending any treatment.

Our Services

Available in every service area. Each recommendation is based on a free water test at your property.

Whole House Water Filtration

A whole house water filtration system treats water at the point where it enters your home, so every faucet, shower, and appliance receives filtered water. It is designed to reduce sediment, chlorine taste and odor, and other common contaminants depending on the media used.

Reverse Osmosis Drinking Water

A reverse osmosis (RO) system forces water through a semi-permeable membrane to reduce a broad range of dissolved contaminants at a dedicated drinking-water tap. RO is commonly used for drinking and cooking water where higher filtration is desired.

Water Softener Systems

A water softener reduces hardness minerals (primarily calcium and magnesium) through an ion-exchange process. Softening addresses the effects of hard water — scale buildup, spots on fixtures, and reduced soap effectiveness — rather than taste or dissolved contaminants.

FREE Water Quality Testing

A free on-site water test measures conditions at your tap — including hardness, chlorine, pH, and other indicators — so any recommendation is based on your property's actual water rather than assumptions. Testing is the first step before any system is recommended.

Well Water Filtration & Treatment

Homes on private wells are responsible for their own water quality. Well water filtration and treatment addresses concerns common to private supplies — sediment, iron, hardness, odor, and bacterial risks — with equipment selected based on a test of your actual well water.

Water System Check & Testing

A water system check inspects your existing filtration or softening equipment — verifying performance, flow, and media condition — and re-tests your water at the tap to confirm the system is still doing its job. It's ideal for homes with older or inherited equipment.

Salt-Free Water Conditioning

Salt-free conditioning systems alter the way hardness minerals behave so they are less likely to form scale — without using salt or sodium. They are a lower-maintenance option for homeowners who want scale protection without the ion-exchange softening process.

Iron & Manganese Filtration

Iron and manganese filtration targets the metals that cause orange, brown, or black staining on fixtures, laundry, and appliances — and metallic or bitter taste. These systems are selected based on the form and concentration measured in your water test.

UV Water Purification

Ultraviolet (UV) water purification uses light to neutralize microorganisms as water passes through the chamber. It is a chemical-free way to address biological concerns and is often added to whole-house systems, especially for homes on private wells.

Filter Replacement

Filter replacement keeps your filtration and softening systems performing as designed. We replace cartridges, membranes, and media on schedule based on your water conditions and usage — whether we installed the system or not.
