The DROP Commercial Control Valve Manual describes the CS125 and CS150 Series valves, which are fully automatic control mechanisms designed for water treatment units. These valves are engineered for ease of serviceability, featuring hand-tighten nuts for inlet, outlet, drain, and water meter access, and quick-access plug-in style for the injector or brine port. Accessing the piston and seals requires removing only five Philips head screws and separating a few plastic clips.

Function Description:

The DROP 1.25" and 1.5" valves direct and regulate all cycles of a water treatment unit. They are designed to improve water quality, provide leak detection, and offer water conservation benefits. The system can operate locally without an internet connection or send mobile alerts when connected to a WiFi network, allowing for remote monitoring and adjustments via a mobile device.

Important Technical Specifications:

The manual provides a quick reference table with detailed specifications for various DROP models (20125X500, 20125X600, 20125X550, 20125X650, 20150X500, 20150X600, 20150X550, 20150X650). These models vary in their piston type (hard water bypass or no hard water bypass during regeneration), injector/plugs configuration, and valve body (CS125 or CS150).

Valve Series - Piston Type / Tank Opening:
- CS125-NHWB (No Hard Water Bypass) - 2.5" with Bypass Valve
- CS125-HWB (Hard Water Bypass) - 2.5" with Bypass Valve
- CS150-NHWB - 4"
- CS150-HWB - 4"
Service Flow Rate (with meter):
- @ 15 psig: Ranges from 24.1 gpm (CS125-NHWB) to 35.6 gpm (CS150-HWB).
- @ 25 psig: Ranges from 31.3 gpm (CS125-NHWB) to 45.9 gpm (CS150-HWB).
Backwash Flow Rate @ 25 psig: Ranges from 20.5 gpm (CS125-HWB) to 26.9 gpm (CS150-NHWB).
Min./Max. Operating Pressure: 20 - 125 psig.
Min./Max. Operating Temperature: 40°F - 120°F.
Outlet water state during regeneration: Shut-off or Inlet Bypassed, depending on the model.
Brine Refill Rate: 3.0 gpm Brine Line Flow Control.
Drain Line Flow Controls: Available in various rates from 2.4 gpm to 25 gpm.
Brine Draw Injector Rates @ 60 psi:
- CS125: Red #0 (0.25 gpm), White #1 (0.35 gpm), Blue #2 (0.5 gpm), Yellow #3 (0.63 gpm).
- CS150: White #3 (1.0 gpm), Green #4 (1.7 gpm), Blue #5 (2.0 gpm).
Distributor Tube Opening: 1.32" O.D. (1" NPS) for CS125, 1.90" O.D. (1 1/2" NPS) for CS150.
Tank Thread: 2 1/2"-8 NPSM for CS125, 4"-8 NPSM for CS150.
Drain Line Connection: 1" NPT Male.
Brine Line Connection: 1/2" Push-Lock.
Default Inlet / Outlet Connections: 1 1/4" NPT Male, 1 1/2" NPT Male.
DROP Commercial Control Board: EVB-029.
Power Adapter: 12 VDC, 2.5mm x 5.5mm Barrel, Center Positive, 1000 mA Min.

The control valve offers two piston options: a hardwater bypass piston (typical for single tank softening systems, allowing hard water bypass during regeneration) and a non-hardwater bypass piston. All pistons feature a patented water shutoff position to protect properties from water damage. When combined with the non-hardwater bypass piston, commercial DROP valves can be used in parallel without external shut-off valves, providing continuous water treatment.

An integral turbine flow meter allows the DROP system to properly protect a property and notify the end user of usage and potential problems. This meter is quick to access and calibrated for excellent accuracy above 0.75 gallons per minute. An optional combination turbine flow meter and pressure sensor can replace the standard flow meter, monitoring system water pressure at the outlet of the valve.

Usage Features:

The DROP system is designed for easy installation, setup, and maintenance. The DROP app provides user control, information, and history of the water treatment system. The app's user interface includes info icons to explain features. Settings relevant to the 1.25" and 1.5" valves are found on the "System > Settings" page and the "Devices > Softener" or "Devices > Filter" pages.

Valve operation is indicated by changing LED colors during regeneration steps. Lights slowly fade from side to side when the valve is in a step, and rotate when moving to a new position.

Softener: Service (Green), Backwash (Purple), Brine Draw (Light Pink), 2nd Backwash (Optional - Purple), Rapid Rinse (Light Blue), Brine Fill (Spring Green).
Backwashing Filter: Service (Blue), Backwash (Purple), Rest (Light Yellow), Rapid Rinse (Light Blue).
Aeration Filter: Service (Blue), Decompress (Pink), Air Release (Lime), Backwash (Purple), Rest (Light Yellow), Air/Chlorine Draw (Light Pink), Rapid Rinse (Light Blue).

Advanced Configuration:

The DROP valve board is factory preset for most installations: Softeners (device #1), Backwashing filters (device #2), and Aeration valves (device #3). Users can change the valve type (Softener, Backwashing filter, Aeration filter), device number (1-4), and softener resin capacity (45k, 60k, 75k, 90k, 120k, 150k, 210k, 300k, 450k grains capacity). This is useful for replacing boards or configuring systems with multiple treatment steps of the same device type in series.

Maintenance Features:

The valve is designed for easy service. The inlet, outlet, drain, and water meter access points use hand-tighten nuts. The injector or brine port plug is a quick-access, plug-in style with a clip. Piston and seal access requires removing five Philips head screws and separating plastic clips.

Brine Line Push-Lock Connection:

To connect brine tubing: ensure the 3/8" tubing is cut squarely and push it 7/8" into the fitting, past the O-ring seal. To release brine tubing: remove the orange locking clip, push in on the gray ring surrounding the brine tube, and pull out the brine tube.
