What It Is - "The Smart Water System," not just a water softener
DROP (full name DROP Connect, parent company Chandler Systems Inc.) is a water treatment company based in Ohio, USA, positioned around a home smart water management system. Its core product is an IoT-enabled water softener, but it goes beyond that: the entire product line is built around protecting household water, integrating softening, filtration, leak protection, and water-use monitoring into one system. At WQA 2026, DROP had its own booth showing the app and connected control valve.

DROP Booth - App Demo
Booth panel: "DROP · The Smart Water System." The phone on the left shows app data (water-use curve + 2,969 gallons of soft water remaining), while the icons on the right highlight the two core functions: Protect and Control.
DROP Valve - Product Hardware
A DROP control valve is mounted on top of the black softener tank, with an orange LED status light on top and a square black valve body. The lower-left booth panel shows a "Conserve" earth icon - water conservation is one of their core selling points.
Four Product Models
DROP Smart Water Softener (standard)Available in 32k/48k/64k grain sizes; removes calcium and magnesium hardness; 9V backup battery; 5-year warranty; connects to the DROP App
DROP City Smart Water Softener (city-water version)Adds chlorine and chloramine removal on top of the standard version, suitable for municipal tap-water users
DROP Duplex (dual-tank standard)Dual tanks in parallel for uninterrupted soft water 24/7, designed for high household water demand; includes leak-protection capability
DROP Duplex City (dual-tank city-water version)Dual tanks + chlorine removal, the most complete configuration; suited for municipal water and high-usage households
Product Features
1
Automatic Water ShutoffWhen a leak is detected, the softener can automatically close the inlet valve to prevent water damage. This was a feature almost no other brand showed at the exhibition.
2
Patented Salt Sensor (DROP Salt Sensor)A built-in sensor monitors salt level and automatically sends push/SMS/email alerts when salt is low. It does not need an add-on external sensor like EZsalt.
3
Real-Time Water-Use MonitoringThe app can show a 24-hour water-use curve and identify abnormal use (such as a faucet left running or a leaking toilet), which is visible directly on the phone screen in the booth photo.
4
Remote BypassThe app can remotely switch the bypass valve, even when the user is away from home. In DROP's comparison table, competitors do not offer this feature.
5
Official Home Assistant IntegrationThis is a detail clearly visible from the booth/site: the website footer has a Home Assistant integration button. This is attractive to technical users and is also EZsalt's weakness, since users complain it does not support HA.
📝 Overall Impression:DROP is not a traditional water softener brand in the usual sense; it feels more like a home water management platform company. The softener is the entry point, while leak protection, water-use monitoring, and water-saving optimization are what it is really trying to do. This positioning felt distinctive at WQA: the booth was not mainly showing tanks and valves, but the app interface.

DROP Ecosystem - Hub at the center, unified control for hundreds of devices
DROP's product logic is to build a home water management ecosystem, with the softener as only one node. All devices connect through the DROP Hub; the Hub communicates with the devices and also goes online so users can control the system remotely.
System Architecture
🔵 DROP Hub (central controller)Each home installs one. It communicates with all devices through DROP Link, a low-frequency mesh radio network; a single Hub can control hundreds of DROP devices. It also connects to home WiFi for remote control.
🟢 DROP Link (self-forming mesh)A proprietary low-frequency mesh protocol that lets devices communicate without depending on WiFi. Even if one node goes offline, the other devices keep working.
🟡 DROP App (control interface)Available on iOS, Android, and web; supports both local and remote control. Includes dashboard, system management, device settings, and notification center.

Channel Strategy
🔧 Certified Installer Network (Installer Program)100+ certified installers across the U.S., including water treatment companies, well drillers, plumbing companies, and more. The official site has an installer map, so users can find nearby DROP installation providers. This channel serves users who do not want to DIY.
🛒 Direct Sales (DTC)Orders can be placed directly on the official website, and products are also sold on Amazon. DROP provides detailed installation videos and documentation and supports DIY installation. The 9V backup battery design keeps the system working during power outages.
💡 Key Insight:DROP's ecosystem logic is similar to Apple's: each device has standalone value, but the greatest value appears when the devices are connected. The Hub is the sticky core; once a home has installed the Hub, the user is more likely to keep buying other DROP devices. This is a classic platform mindset.

DROP vs EZsalt - Two different IoT paths
EZsalt: add-on sensor, dealer-facing B2BIt does not change the existing equipment; it adds a sensor. The core value is helping dealers build delivery subscription revenue. The user experience is extremely simple (reply YES by SMS), and the dealer is the core customer. Software is the weak point, with no Home Assistant support.
DROP: integrated smart complete unit, end-user-facing B2CThe softener itself is smart, so no extra hardware is needed. The product line spans softening, leak protection, and water-use monitoring, forming an ecosystem. It supports Home Assistant, is DIY-friendly, and appeals to technical users.
DROP softener installation example
Official installation photo: a DROP water softener installed in a basement, with the valve visible; the overall setup is very compact
DROP Hub central device
The DROP Hub is the core of the whole system and manages all devices in one place. Each home installs one, and it communicates with devices through DROP Link.
⚠️ DROP's Limitations:DROP is a complete-unit brand, not a control-valve supplier. Its competitors are consumer-product companies such as GE and Whirlpool, not control-valve suppliers such as Clack or Runxin. Its channels are mainly DTC and certified installers, not the water-softener dealer system - which is very different from the market logic of Clack/Runxin.
💡
Takeaways for Us - Personal view, for reference only
DROP and EZsalt represent two very different IoT paths, which makes the comparison more interesting. The following are a few personal thoughts; colleagues with more experience are very welcome to add or correct.
🗺️
DROP chooses the B2C path, which differs from the traditional water softener control-valve marketTraditional water softeners are sold to users by dealers/installers, and users often do not know which brand of valve is inside. DROP bypasses this system and speaks directly to consumers with the concept of smart-home water management, competing head-on with GE and Whirlpool. This path requires strong branding, but if it works, user stickiness can be very high because the whole system is DROP.
🔌
Home Assistant integration is a hidden competitive advantageEZsalt users complain about the lack of HA support, while DROP has an official integration. North American tech users (engineers, enthusiasts) are highly receptive to HA, and this group is often the main force behind DIY softener installation. HA integration means the system can link with Alexa, Google Home, smart thermostats, and more, making it a real part of the smart home rather than just a standalone app.
🛡️
The "leak protection" angle is smartThe official site opens with the idea that the probability of suffering water damage is six times higher than suffering a home burglary. This reframes the softener from consumable management to home insurance. Users are more willing to pay for peace of mind than for softer water. If control valves move further toward intelligence in the future, protecting the home will be more persuasive than monitoring water quality.
🔧
DROP shows the ceiling for control-valve intelligenceWhat DROP delivers includes salt-level monitoring, water-use analysis, leak detection, automatic shutoff, temperature monitoring, remote bypass, and device maintenance reminders. This is the complete picture of turning the valve from an actuator into a data node. For us, it is both a reference benchmark and proof that the direction is technically feasible; it just requires enough software investment.
⚠️
DROP is not our direct competitor, but it is worth watchingDROP's control valve is self-developed and not sold externally. DROP is a complete-unit brand that uses DTC and certified installer channels rather than the traditional water-softener dealer system. So its path runs parallel to ours as a control-valve supplier, rather than directly competing. But if its model is validated, more complete-unit brands may follow, ultimately affecting the market space for valve suppliers. This is a direction worth watching over the long term.
📌 One-sentence summary:DROP represents a complete vision for water softener IoT: not just data visibility, but active protection, system linkage, and whole-home water management. It proves that users, especially North American middle-class households, are willing to pay a premium for smarter water management, and it also proves that software and ecosystem are harder to copy than the hardware itself.For us, DROP is a reference object worth studying, not a current competitor.
