The DROP Duplex City Water Softener is a professional grade smart system that provides 24/7 soft water and progressive flow to efficiently meet the fluctuating demands of a busy household while also protecting from costly water leaks.

City Water Softeners provide all of the benefits of the Smart Water Softeners with the added ability to remove unwanted chemicals present in most municipal water supplies such as chlorine and chloramine. The mineral tank of a city water softener is divided into two sections. The first section is filled with catalytic carbon that removes the chemicals and the second section is filled with high-performance ion exchange resin to soften the water.

Like all DROP water softeners, the Duplex City Water Softener utilizes a patented piston design that provides the ability to shut off water to the home. When paired with DROP Leak Detectors through the DROP Hub, this system provides all the benefits of a top of the line water softener, home leak protection, and a water conservation system in one.

Automatic Leak Protection

All DROP Smart Water Softeners utilizes a patented piston design that provides the ability to shut off water to the home automatically if a leak is detected. This can save you thousands on undiscovered water leaks and resulting water damage.

This next-level home protection feature will immediately send you a notification of the event, and can even be fine-tuned via the settings.

Boost Hair, Nail & Skin Health

Our smart water softening systems eliminate calcite minerals like magnesium and calcium carbonates that cause hard water. Soft water, devoid of these mineral deposits, leaves less residual material on your hair, skin, and nails after showering. Consequently, it eases dryness, resulting in smoother, more manageable hair, fewer split ends, less dry skin, and robust, less flaky nails.

Cleaner Dishes

Discover the difference of cleaner dishes with DROP water softeners. Soft water delivers 6x more spotless dishes and also significantly saves on your detergent costs by up to 70%!* According to the WQA.

Plus, get the most out of air drying—which works best with softened water—and save on your electricity bill by ditching the dishwasher’s heating feature. Invest in DROP water softeners for a hassle-free and money-saving dishwashing experience.

Better Tasting Water

Employing a process of ion exchange, our water softeners channel the hard water through resin bead-filled tanks. The positively charged resin beads attract and hold onto minerals such as calcium, magnesium, and traces of iron and manganese. Say goodbye to these impurities and hello to refined, improved water with a notably better taste.

Choose our reliable, high-quality water softeners for a noticeable improvement in your water quality, and start enjoying softer, better-tasting water in your home!

Save Money

Investing in a water softener for your home has several financial benefits. Not only will you prolong the lifespan of your appliances, reducing maintenance costs, but you’ll also use less soap, shampoo, and laundry detergent due to the soft water’s effect on detergents.

Your clothes will remain vibrant and last longer, minimizing your wardrobe expenses. Plus, with no harsh deposits left by the water, you’ll save on time and the cost of cleaning agents to remove them, making this a smart, cost-effective investment for your household.

The Benefits of DROP

The DROP App contains a robust amount of notifications to keep you informed. Everything from Leak Detection to Low Salt notifications, DROP has your back for all system events and items. They can be configured to push notifications, text messages, and emails.

Below is a list of all of the unique notifications available to you.

Automatically Respond to Detected Leaks

Worried about water leaks and damage to your home? With DROP Leak Detectors, you will never have to worry about that again! These sensitive devices can detect small traces of water where there should be none. You can configure these leak detectors to notify you of the issue as well as automatically shut off your water through your softener, filter or home protection valve to prevent further leaks and damage.

Long Flow Notification

Has someone left a sink running? This notification will inform you if water is running longer than expected based on your preferences.

Valve Error Notification

Has your softener or filter control valve malfunctioned? This notification will provide you with the correct information to help assess any valve issues in your water softener and/or water filter control valve.

Component Communication Lost Notification

DROP constantly communicates with its device endpoints. If your system is having trouble communicating with one of the devices, you will be notified and able to fix the problem.

Low/High Temperature

DROP Leak Detectors have the ability to notify you of temperature changes based on your preferred temperature ranges. If you lose heat in your home, your DROP Leak Detector will notify you.

Low Salt Notification*

Is your water softener running low on salt? With our patented DROP Salt Sensor, you will be notified if more salt is needed to continue providing softened water.

Slow Leak Test**

This unique test provides the status of your water system overnight by checking for small water leaks. By depressurizing your water pipes while you sleep, we can detect even the smallest leak in your system and help you identify where that is.

Filter Cartridge Notifications

Is your Whole House Cartridge Filter in need of a cartridge replacement? This notification will inform you to replace your cartridge to continue filtering and cleaning your home water.

Power Loss/Restored Notifications

Ever lose power to your important electronic devices and not know about it? This notification will notify you of this event. Never fear, as DROP uses battery backups on nearly all of its devices to continue operating without power.

Low Battery Notifications

DROP Leak Detectors and other DROP components operate on batteries using very low power consumption capable of lasting for years. If these batteries run low in power, you will know when to replace them.

Leaky Toilet Notification

Our technology is able to detect whether your toilet is leaking or not by pinpointing how much water is used during and after a flush.

Water Usage Surpassed Setpoint

Want to know when you have used a certain amount of water? This notification will let you know when you have crossed water use thresholds based on your preferences.
