Walk through the options

Water filtration options in Sun City, AZ

Taste, odor, spotted dishes and scale on fixtures are different concerns, and each points toward a different kind of treatment. Trident Plumbing & Drain installs reverse osmosis, carbon filtration and water softening systems and helps match the system to your household.

Start by noting what bothers you about the water and where you notice it: drinking water at the kitchen tap, the shower, or dishes and appliances. Our Peoria office can arrange a visit to discuss the options and how each would connect to your existing plumbing.

Signs worth noting

Clues that your water could use treatment

A metallic, chemical or chlorine taste or smell can prompt a closer look at filtration. Cloudy water or visible particles, and a film or spots on glassware after the dishwasher, are other clues worth writing down.

Some households notice dry skin or dull hair after bathing, or a coffee maker or ice machine that seems to underperform. These observations do not identify a specific substance, but they help narrow which kind of system is worth discussing.

Drinking water, taste and odor

Reverse osmosis and carbon filtration

Reverse osmosis pushes water through a semipermeable membrane that reduces a wide range of dissolved substances. It is typically installed to treat drinking water at a specific tap, often in the kitchen.

Carbon filtration traps impurities that affect taste and odor, including chlorine. It suits households whose main complaint is how the water smells or tastes. The two approaches can be combined when both drinking water and general taste matter.

Minerals and scale

Where a water softener fits

A water softener addresses the minerals that leave scale inside pipes, water heaters and appliances and spots on fixtures. Softening and filtration solve different problems, so a softener is often one part of a treatment plan rather than a substitute for a filter.

Reducing scale can help water-using equipment work as intended and limit the buildup that leads to repairs. Ask how a softener would be sized for your household and where it would connect to the plumbing.

After installation

Keeping a treatment system working

Every system needs periodic attention. Filters and membranes are replaced on a schedule, and softeners need routine checks. Ask how often the components in your system need service and which changes in the water would signal that service is due.

If a taste or odor returns, or spots reappear, mention when the system was last serviced. Trident can check the installation and the connected plumbing. The memberships page also lists plans for softener salt service and reverse osmosis filter changes.

Read the numbers

Use EPCOR's report to choose a treatment

EPCOR publishes a water quality report for its Sun City system each year, and the 2025 edition includes data collected through 2025. It lists hardness of 7 to 11 grains per gallon, total dissolved solids of 223 to 372 parts per million and chloride from 28 to 107. Sodium, last sampled in 2024, ranged from 31 to 79. Arsenic's highest detected level was 6.3 parts per billion, against a federal limit of 10.

Each number points to a different tool. A softener handles the calcium and magnesium behind scale, carbon filtration targets chlorine taste and odor and reverse osmosis reduces dissolved minerals at a drinking water tap. Before buying, check the certifications for what a system claims to remove. EPCOR's report adds that skipping maintenance on a home softener or reverse osmosis unit can result in poor water quality, so plan for upkeep.

Treatment costs

What sets the price of a treatment system

The price follows whether you treat the whole house or one tap, and what the system has to take out. These factors account for most of the difference.

Our special offers page lists the current discount on a new softener or filtration system, along with its terms. The reverse osmosis membership includes a filter change every year for five years, though sanitizing is not part of it.

  • A whole-house system or treatment at one drinking water tap.
  • Softening, carbon filtration, reverse osmosis or a combination.
  • Space, drain and power at the spot where the system goes.
  • How often filters, membranes or salt need replacing.
  • Taking out an old softener or filter.

From the 2025 report

What EPCOR's report lists for this system

These figures come from EPCOR's 2025 water quality report for its Sun City system. They help match a treatment system to what is in the water.

Total dissolved solids in 2025 samples
223–372 ppm

Dissolved solids ranged from 223 to 372 parts per million across EPCOR's samples. Dissolved minerals shape taste and leave spots, which reverse osmosis is designed to reduce.

Chlorine residual range in 2025
0.82–0.91 ppm

EPCOR adds chlorine as a disinfectant. If its taste or smell bothers you, carbon filtration is often chosen to address it.

water filtration in Sun City.

Questions about water filtration in Sun City? Start here, or tell us what is happening at your home.

Ask our team
Which system helps with taste and odor?

Carbon filtration is often chosen for taste and odor concerns such as chlorine. Reverse osmosis treats drinking water more thoroughly at a single tap.

Does a water softener filter my water?

No. A softener reduces the minerals that cause scale. Taste, odor and dissolved substances are addressed by filtration systems such as carbon or reverse osmosis.

Can I combine more than one system?

Yes. Some households pair a softener for scale with reverse osmosis for drinking water. The combination depends on the concerns you want to address.

How do I know which option suits my home?

Note the problems you see, where they appear and how your household uses water. Trident reviews those details and explains the options that fit.

Does EPCOR soften the water in Sun City?

No. EPCOR's 2025 report states that it does not treat drinking water for hardness, and it lists 7 to 11 grains per gallon. A softener at the home is the way to reduce it.

What does EPCOR suggest if I am worried about lead?

Its report suggests running the tap, a shower or a load of laundry for several minutes before drinking, and notes that a filter certified by an American National Standards Institute accredited certifier can reduce lead. Its lead testing page lists licensed labs. EPCOR adds that it cannot control the materials used in the plumbing inside your home, and that you share responsibility for identifying and removing any lead materials there.
