Commercial operations can't tolerate scale or downtime. Fleck commercial valves (2900, 3150, 3900, NXT) handle high flow and large resin volumes, and twin-alternating configurations keep soft water flowing 24/7 while one tank regenerates.
| Valve | Typical use |
|---|---|
| 2900 | Light commercial / high-flow residential |
| 3150 | Commercial 1.5" high-flow |
| 3900 | 2" high-capacity commercial/industrial |
| NXT | Programmable commercial control |
How to size a commercial Fleck system
- Match the valve to peak flow (gpm) so pressure holds at full demand.
- Size capacity to daily gallons × hardness (add iron load).
- Use twin-alternating for 24/7 operations (restaurants, hotels, laundries, boilers).
Tell us your peak flow, daily volume and hardness and we'll spec the system and ship it.

Frequently asked questions
How do I size a commercial water softener?
Size the valve to your peak flow in gpm and the capacity to daily gallons × hardness (plus iron). Twin-alternating systems give uninterrupted soft water. We'll spec it for your application.
What is a twin-alternating commercial softener?
Two resin tanks alternate so one is always in service while the other regenerates — essential for restaurants, hotels and 24/7 operations.
Which Fleck valve for commercial use?
2900 for light commercial, 3150 (1.5") and 3900 (2") for higher flow, NXT for programmable control. Match to your peak gpm.
