What is Reverse Osmosis?


Reverse osmosis is a multi-stage filtration process that removes:


  • Dissolved solids (TDS)
  • Lead
  • Arsenic
  • Nitrates
  • Fluoride
  • Chlorine and chloramines
  • Sediment and contaminants


An RO system is typically installed under your kitchen sink and provides purified drinking water through a dedicated faucet.

Benefits of Reverse Osmosis:


  • Better-tasting water
  • Removes up to 99% of dissolved contaminants
  • Reduces bottled water use
  • Protects coffee makers and appliances
  • Healthier water for cooking and drinking

Why Phoenix Homes Need Water Treatment


Phoenix has extremely hard water, often measuring over

15–20 grains per gallon.


Hard water can cause:


  • Scale buildup on faucets and shower heads
  • Reduced water heater efficiency
  • Premature appliance failure
  • Dry skin and brittle hair
  • Spots on dishes and glassware


Do You Need an RO or Water Treatment System?


You may need water treatment if:

  • Your water tastes metallic or bitter
  • You see white scale buildup
  • Your water heater fails prematurely
  • Your skin feels dry after showering
  • You buy bottled water regularly


Not sure what system is right for your home? We provide free water quality testing and honest recommendations.

  • How long does a reverse osmosis system last?

    Most RO systems last 10–15 years with proper maintenance. Filters typically need replacement every 6–12 months.

  • Does reverse osmosis remove fluoride?

    Yes, RO systems remove fluoride along with many other dissolved solids.

  • Is Phoenix water safe to drink?

    Phoenix water meets federal safety standards, but it contains high mineral content and chlorine that affect taste and can damage plumbing over time.

  • How much does a water softener cost in Phoenix?

    Costs vary based on system size and installation requirements. We provide upfront pricing after testing your water and evaluating your home.

  • Do I need both a water softener and RO?

    Many Phoenix homeowners install both. A softener protects the home’s plumbing, while RO provides purified drinking water at the sink.
