DESCRIPTION

Hard water is bad for houses. For a business, it's a line item.

Scale clogs commercial dishwashers, coffee machines, boilers, and ice makers, then you pay for downtime and repairs. The Pentair Fleck Commercial Water Softener is built for the volume that restaurants, hotels, offices, laundromats, and multi-unit buildings put through the pipes.

Commercial-grade Fleck control. Big capacity. Proven Pentair engineering.

Your equipment keeps running. Your repair guy gets lonely.

HOW TO USE
  1. Get it sized right. Commercial sizing depends on peak flow, daily gallons, and hardness. Call the QWT tech team before you order.
  2. Have a pro install it on the main line with a proper drain and power.
  3. Program it to your usage so it regenerates during off-hours.
  4. Keep the brine tank stocked and schedule periodic checkups.
HOW DOES IT WORK

Same chemistry as a home softener, built bigger.

Water flows through large resin tanks, where resin beads pull out calcium and magnesium through ion exchange.

The Fleck control valve tracks your water use and runs regeneration when the resin is spent. Brine rinses the minerals off and flushes them to drain.

Result: soft water at commercial flow rates, without scale wrecking your expensive gear.
