OVERVIEW

BENEFITS OF A WATER SOFTENER

Hard water levels can range from low to very high hard water. Homeowners with any level of hard water can face issues like prematurely broken water heaters and persistent scaling, spotty dishes and glassware, dingy and stiff laundry, itchy skin, and dull hair. With a Pentair Water Softener, you can reduce the havoc hard water can cause to your home and can save salt and water with our on-demand regeneration feature. When you insist on Pentair, you can expect better quality water from every tap in your home. Pentair recommends that you test your water hardness levels using our 16-Point Rapid Water Test to ensure the water softener is right for your home water. Additional features include:

1. Simple, electronic system for easier programming
2. Self-cleaning brine injector reduces maintenance
3. Only regenerates when needed, saving salt and water
4. Singular rotary disc seal means longer product life and less maintenance Remote monitoring and low-salt level alert when paired with the Connected Salt Level Sensor and the Pentair Home App

How it works Resources Specification Education Support Reviews

1. Softening

Occurs when water passes through the mineral tank where positively-charged calcium and magnesium ions are exchanged with sodium onto the negatively-charged resin beads. The calcium and magnesium are retained on the media within the resin tank while the remainder of the water with sodium ions flows into the home, resulting in softened water. Eventually, all sodium ions are exchanged with the magnesium and calcium on the resin beads fill with calcium and magnesium and need to be regenerated.

2. Regeneration

The mineral tank is recharged with sodium from the brine tank solution and displaces calcium and magnesium, which is flushed down the drain during the backwashing phase.

3. Backwashing

At the end of the regeneration process, this stage is a final removal of the hardness ions and dirt that has accumulated in the mineral tank and flushes to the drain.

4. Rinse

The mineral tank is rinsed with fresh water and loads the brine tank so that it is ready for the next softening cycle.

5. Controller

Recharging cycles are controlled by the electronic meter on the top of the tank. This can be set to recharge every specified number of days or as the electronic head recognizes that a certain amount of water has been used.

Frequently Asked Questions

01. Can I install the PAC Series outside?: We recommend this system not be exposed to outdoor elements like direct sunlight or atmospheric precipitation. But if you do install outdoors, we offer an outdoor weather cover accessory that will help protect the valve head from elements. This system can also be installed in a covered, open-air structure like a carport or basement.

02. Which model is right for me?: The PAC4 is ideal for homes that have 1 to 3 bathrooms and standard daily water usage. The PAC7 is the right choice for homes with 4 to 6 bathrooms and standard daily water usage.

03. How much maintenance is required?: Little maintenance is needed to keep your water softeners functioning smoothly. Salt does need to be refilled as it is depleted and filters and media should be replaced as indicated in your owner’s manual.

04. Does this system reduce microorganisms?: No. If you are concerned about microbial contaminants like viruses and bacteria, we recommend installing a Pentair UV Disinfection System.
