Detailed Valve Description
The DROP 1” valves are fully automatic control mechanisms to direct and regulate all cycles of
the water treatment unit. The control valve has been designed to make it easily serviceable. The
inlet, outlet, and access to the water meter are all hand only tighten nuts making them quick and
convenient to service. Removing the drain line is a quick access style with a clip. Accessing the
injector or the brine port plug is easily done, only needing a standard screwdriver to remove the
access cover. Accessing the piston and seals only requires removing 5 screws and separating a
few plastic clips by hand. All of this means that the valve is quick and simple to service and you
do not need any specialized tools to work on the valve.
The control valve comes with the proprietary DROP piston. This piston can operate all standard
softener and filter valve functions with the addition of being able to bypass water, without opening
the drain port and shut-off the water to the outlet with the drain either open or closed. All DROP
pistons have a patented water shutoff position (U.S. Patents 9714715 & 10012319), which can be
used by a DROP system to protect properties from the risk of water damage from leaks and water
breaks. The control valves / pistons are only available in downflow regeneration.
The unique DROP RS1 power head is a compact design that is also designed to be quick to
service in the field. The powerhead is simple to remove from the valve body for quick access to
the piston stack. The RS1 power head utilizes a slide cover for protection from falling water and
allowing easy removal for service.
The softener and aeration filter valves have a patented motorized brine/chemical feed valve (U.S.
Patents 8535540 & 9212070). Because the valve is separately controlled from the main piston it
allows precise control over the brine fill and draw times, or in an aeration filter valve allows com-
plete control over chemical injection into the media tank.
The DROP 1” valves are able to easily be used in parallel when they are used with the motorized
bypass option. The motorized bypass is another patented feature of the DROP 1” valve (U.S.
Patent 10633262). When the motorized bypass is installed the DROP valve will be able to use
treated water from other valves plumbed in parallel during the regeneration cycle positions. This
allows for reduced maintenance on the system since filtered / softened water is used.

OPERATIONS
All DROP 1” valves include a turbine flow meter that is integral to the valve body. The meter is quick to
access without having to separate any plumbing in case of needing to service the meter. Simply turn
the bypass valve to bypass and loosen the nut securing the water meter, then pull on the tab to remove
the meter from the outlet port of the valve. The meter is calibrated in the Chandler Systems lab and has
excellent accuracy at all flows above 0.25 gallons per minute. The meter allows the DROP system to
properly protect a home and to notify the end user of usage and potential problems.
Combining these control valves with a DROP control system creates a water treatment system that is the
easiest in the industry to install, setup and maintain. The DROP system gives the end user easy control,
information, and history of the water treatment system. DROP is a unique water management system.
Using the DROP Hub, DROP monitors water usage and manages the water-related devices throughout
the entire installation. DROP can operate locally without an internet connection or has the added ability
to send mobile alerts when connected to a WiFi network. This advanced system can allow remote moni-
toring and adjustments—all from your mobile device.
Valve Operation
The DROP Users Guide (https://dropconnect.com/knowledgebase-resources) gives general information
and help with connecting your DROP system to a WiFi network and connecting devices to your DROP
Hub. It also gives some general information about making settings and navigating the user interface in
your DROP app. It is also helpful to know that throughout the app’s user interface there are small info
icons to help explain all the features in the app. The settings that are relevant for a DROP system with
the 1” valves installed are found on the System > Settings page and the Devices > Softener or
Devices > Filter pages in the DROP app.

OPERATIONS DROP VALVE - LIGHTS - REGENERATION
DROP Lights - During Regeneration
When a treatment valve is in regeneration the lights will change color for each step in the regeneration
process. While the valve is sitting in a step of the regeneration process the lights will be slowly fading from
side to side (wobble). If the valve is moving to a position the lights will rotate according to the direction of
the motor movement to get to that position. The colors for each position are as follows:
Position Color
Service Green
Backwash Purple
Brine Draw Light Pink
Rapid Rinse Light Blue

OPERATIONS ADVANCED CONFIGURATIONS
Advanced Conguration of Valve Device Components
The DROP 1” valve board is used on several configurations of DROP products. These products will
come with the board already setup, ready to use for most installations.
Valves from the factory are preset as follows:
• Softeners are set to device #1
• Backwashing filters are set to device #2
• Aeration valves, including Sidekick aeration valves are set to device #3
• Cartridge filters are set to device #4
These factory presets allow for simple setup without the need for Advanced programming in a majority of
installations. Some situations, however, may cause you to need to change the configuration of the board.
There are up to three settings available on the valve board configuration.
1. The valve type. The options are: Softener, Backwashing filter, Aeration filter, Sidekick
aeration filter, and Cartridge filter.
2. The device number, which can be set from 1-4. Every stage of water treatment that you have
needs to have a unique device number. (Note: The physical water treatment order of the
devices in the system is unrelated to the device number.)
3. The softener resin capacity. This is available if the first option is set to Softener. The
capacity can be set to 24k, 32k, 48k or 64k. These are quick common settings, that should be
set according to the amount of resin in the media tank. Full control of the resin capacity setting
is available in the Devices > Softener > Advanced page in the App.
There are two main situations that might cause you to need to change the device configuration on a
DROP valve control board. The first situation that may cause the need to change the device configura-
tion is in the case of replacing a board in the system. If a generic DROP valve board is used, it may need
configured to match the system that it is being installed into.
A less common reason to change this setting is as follows. A simple system will typically have 1 to 2 treat-
ment stages each with only one tank. For example, a softener and a Sidekick filter. These will come from
the factory already set up with a unique device number. Also, if you want to use two of the same type of
treatment device in parallel to treat your water, the DROP system will automatically know to set up two
softeners (which would have the same device number from the factory) as parallel units. However, the
factory default value will not work properly when you have a system that needs two treatment steps using
the same type of treatment device. For example, a backwashing carbon filter and a backwashing neutral-
izer filter that are used in series with each other. In this case the device number of one of the backwash-
ing filters will need to change and it cannot be the same as any other valve device number already on
the DROP system. Only DROP Softener and Filter devices have device numbers. This does not apply to
other types of DROP devices.

OPERATIONS ADVANCED CONFIGURATIONS
Steps for advanced conguring of valve device components
Follow the steps below to change the device configuration of a board, or these steps can be followed to
find out what the current configuration of a board is set to. 1. If the valve is powered up, unplug it (and
remove the battery if installed).
2. Depress the pushbutton on the valve board while plugging in the valve. The board will begin
throbbing the LEDs white. Release the pushbutton.
3. The valve will display a light code to identify its configuration. Repeatedly give a short press on
the button to select the correct device type according to this list:
a. 1 green LED: Softener
b. 1 blue LED: Backwashing filter
c. 2 blue LEDs: Backwashing filter with Aeration
d. 3 blue LEDs: Sidekick filter
e. 1 cyan LED: Cartridge filter
4. With the correct device type code displayed, hold the button down for 2 seconds and the LEDs
will all turn green to indicate the selection is accepted.
5. Next, you will see 1 to 4 white LEDs. Repeatedly give a short press on the button to select the
valve device number for the board with 1 to 4 lit LEDs. All the device components in the same
logical device must use the same device number. (Example: a softener with multiple tanks).
Device components of different types must use different device numbers. (Example: a softener
and a filter). Hold the button for two seconds to accept the selection.
6. If the device type was selected to be a Softener in step 3, then one or more LEDs will be lit
yellow. Repeatedly give a short press on the button to select the correct resin capacity
according to this list:
a. 1 yellow LED: 24,000 grains capacity (3/4 cu. ft. of softener resin is in media tank).
b. 2 yellow LEDs: 32,000 grains capacity (1 cu. ft. of softener resin is in media tank).
c. 3 yellow LEDs: 48,000 grains capacity (1 ½ cu. ft. of softener resin is in media tank).
d. 4 yellow LEDs: 64,000 grains capacity (2 cu. ft. of softener resin is in media tank).
7. With the correct capacity LED code displayed, hold the button down for 2 seconds and the
LEDs will all turn green to indicate the selection is accepted. When the button is released, the
valve will restart and is ready for use.

MOTORIZED BYPASS
1” Motorized Bypass
The Motorized Bypass is used to enable parallel DROP softeners or filters to increase the treatment flow
capacity, or to allow for continuous service and maximizing softener efficiency. The motorized bypass op-
tion should be ordered from the factory on valves that are to be installed in parallel. The motors and the
handles of a bypass are interchangeable incase manual operation is desired in a maintenance situation.
Pay attention to the alignment of the valve stems when interchanging them.
