Detailed Valve Description
The DROP 1.25” and 1.5” 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, drain and access to the water meter are all hand only tighten nuts making them quick and conve-
nient to service. Accessing the injector or the brine port plug is quick access plug-in style with a clip, pos-
sibly only needing a flat head screwdriver to open the plug. Accessing the piston and seals only requires
removing 5 Philips head 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 has two piston options. The first is a hardwater bypass piston, which allows hard water
to be bypassed from inlet to outlet during the valve regeneration cycle. This is typical on a single tank
softening system. The other option is a non-hardwater bypass piston option, which does not bypass
hardwater from the inlet to the outlet during the valve regeneration cycle. All 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. When combined with the
non-hardwater bypass piston type, this feature allows the commercial DROP valves to be used in paral-
lel without the need of external shut-off valves. When used in this way, the DROP system can provide
continuous treatment of water. The DROP hub can command valves to be in service, providing treated
water, or in stand-by with outlet water shut off waiting for when it is needed. During the regeneration
process, inlet water is used to perform the steps of the regeneration of the softener tank and the outlet
water port is shut off. For more detailed information about multiplexing DROP valves, see our “Multiplex-
ing Filters and Softeners” Application Manual. The control valves / pistons are only available in downflow
regeneration.
The DROP 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 or turn the water off in the DROP App and loosen the nut securing the water
meter, if necessary, use a flathead screwdriver under the edge to remove the flow meter from the outlet
port of the valve. The meter is calibrated in Chandler Systems lab and has excellent accuracy at all flows
above 0.75 gallons per minute. The meter allows the DROP system to properly protect a property and to
notify the end user of usage and potential problems.
There is also a combination turbine flow meter and pressure sensor that is optionally available. The com-
bination meter can directly replace the standard flow meter as it plugs directly into the same wire connec-
tion. Once installed, the DROP system can then monitor the system water pressure at the outlet of the
valve. The water pressure can then also be viewed by the user in the DROP App.
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 monitor-
ing and adjustments—all from your mobile device.
