What's the Difference between the Models?

We offer the 5600, 2510, 7000 and 2750 models for single tank Water Softeners and the 9000 model for twin tank Water Softeners.

Fleck 5600, 2510, 7000 and 2750 Models (Single Tank Water Softeners)
Single tank Water Softeners are the most common application. They include a single resin tank with the Fleck 5600, 2510, 7000 or 2750 control valve and a separate brine tank. There are a few differences between the 5600, 2510, 7000 and the 2750 models:

First, the 5600 is designed for use on Water Softeners from 15,000 to 64,000 grains of capacity while the 2510 and 7000 models extends upward to 110,000 grains of capacity. The 2750 model is designed for 40,000 to 110,000 grain capacity water softeners.

Secondly, the 5600 and 7000 have one electric motor that operates the valve's regeneration/backwash cycle and the piston inside the valve during regeneration/backwash while the 2510 and 2750 valves have two motors; one for the regeneration/backwash cycle and a second motor which operates the piston inside the valve. This makes the 2510 and 2750 valves a bit more "heavy duty" as there are two motors performing the operation of the valve.

Finally, the 5600 and 2510 are 3/4" control valves, the 2750 is a 1" control valve, while the 7000 is a 1-1/4" control valve. This means that the valve body is internally sized at 3/4", 1" or 1-1/4". The 5600 and 2510 have 3/4" or 1" connections available using either a yoke or bypass valve. The 2750 valve must be directly plumbed to which means if you require a bypass of the system, it must be accomplished in your plumbing configuration. The 7000 valve (bypass valve standard) has 1" or 1-1/4" connections available.

All four models are very good valves! The 5600 has been around since 1979 and is very dependable. The 2510, 7000 and 2750 are also great valves that will last for many years of trouble free operation.

Fleck 9000 Model (Twin Tank Water Softeners)
The 9000 model controls a twin resin tank system and also has a third, separate brine tank. Twin tank systems soften your water using one of the two twin tanks at a time. When the first tank is being regenerated, the second tank takes over the softening process. This way, you'll never be without soft water even during the regeneration period!

The 9000 control valve is available in 3/4" or 1" models. The 3/4" model has 3/4" or 1" connections available using either a yoke or bypass valve. The 1" model must be directly plumbed to which means if you require a bypass of the system, it must be accomplished in your plumbing configuration.
