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 smart water softeners, the 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.

Key Features:

  • Eliminate hardness caused by calcium & magnesium for improved water quality
  • Effectively reduce chlorine and chloramine for fresher-smelling and more pleasant-tasting water
  • Effortlessly monitor and manage water shut-off remotely using the DROP App
  • Stay informed with real-time notifications, texts, and emails for low salt levels and other system alerts
  • Enjoy peace of mind with a comprehensive 5-year warranty included

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 DROP App

  • The DROP app offers real-time alerts and notifications that keep you constantly updated about your water usage and system status.
  • Not tech-savvy? No problem! Everything you need, from controls to troubleshooting, is found within the app. Its intuitive design makes it accessible, easy to navigate and understand.
  • The app enables easy transition between different DROP systems, making it perfect for those managing multiple locations.

How It Works

  • Carbon Filtering: Our City Smart Water Softener has a unique feature for chemical removal. The first section of the mineral tank is filled with catalytic carbon that effectively eliminates unwanted chemicals such as chlorine and chloramine, common in most municipal water supplies.
  • Ion Exchange: After hard water enters through the inlet pipe and flows through the catalytic carbon, it hits the resin bed. The resin, covered in sodium ions, swaps these ions with with calcium and magnesium ions, creating soft water.
  • Soft Water Distribution: The newly softened water circulates throughout your home via the outlet pipe.
  • System Regeneration: Over time, the resin’s sodium ions deplete, and the system triggers a regeneration process. This is based on hardness level and water consumption.
  • Regeneration: During regeneration, the system flushes out dirt, refreshes the resin with a high concentration salt solution from the brine tank, and rinses the resin. The brine tank then refills, preparing for the next cycle.

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.

* Specific notification for DROP Water Softeners only.

    We are very pleased with our DROP City Water Softener. We’ve noticed a major improvement in the quality of our water. We no longer have the mineral build up in our sinks, faucets, etc. Also, our skin feels much better after we take a shower.

    It gives us peace of mind knowing that the DROP System is doing a great job filtering and conditioning our water. We no longer hesitate grabbing a glass of water from our faucet as we know the water is safe to drink.

    The water leak detection system is an awesome feature as well. We had a slight water pipe leak under our kitchen sink and we were notified immediately via a text message to our cell phones. We were able to correct the issue asap.

    A special thank you to Josh from Complete Water Systems for a job well done. He has been very attentive and is very knowledgeable about the DROP System. He is the reason we purchased this product. We we will recommend the DROP System to all of our family and friends.

    We purchased the 48K Drop City Softener because of the remote manageability, rich feature set, and Chandler support. It has been in service almost two months. This was our first water softener. Before we purchased the softener, our water hardness was 7 gpg and was leaving hard water deposits on our sinks and fixtures. We were replacing our hot water heater with a tankless Rinnai and the Rinnai manual stated – “If you install this water heater in an area that is known to have hard water or that causes scale build-up, the water must be treated and may require a more frequent flushing schedule. Damage caused by lime build-up is not covered by the water heater’s warranty.”. After reading that, we decided it was time to purchase a water softener.

    Before and after our Drop City Softener purchase, I spoke by phone and email on multiple questions that Chandler support promptly answered. During and after the softener installation, the app and drop.io website provide setup configuration, real time current water flow, average daily gallon usage, soft water remaining in gallons, event log, and numerous charts. I was able to configure and customize all the softener settings in the app using my phone or on my PC using the drop.io website. I love the app. I upgraded each components firmware after they were added to the system. The system sends me SMS txt messages and emails on issues including when the salt is low. The Drop Control Valve and Drop Hub have battery backup in case of a power failure. I configured the leak detectors to turn off the water to the entire house if they detect water. I can turn off/on the water to the entire house or bypass the softener using the app or website. There is a Remote Assistance option on the website that states: “Remote assistance allows our support technicians to temporarily access your DROP system remotely. This will allow our support technicians to see your DROP system’s logs and settings to quickly diagnose an issue or assist with setup. Please note that you must call our support line in order for our support technicians to see your request.”. That is a nice feature. The Drop Connect app and website are invaluable.

    Because we only use approximately 100 gallons of water/day during the winter, my first regen did not happen until 50 days after installation. I configured the softener to regen based on “soft water remaining” and not to regen after x number of days. This saved on salt consumption and water. My water hardness was 7 gpg before the softener was installed. The water hardness was 0 gpg after the softener install. I tested it 50 days later, before the first regen, and the water hardness was still 0 gpg. I use a Hach drop count titrator kit to measure the water hardness.

    I have two sets of valves mounted above the softener. They allow me to send “soft water” or “untreated water” to my two outside spigots independently. I use soft water when washing the vehicles to prevent hard water spotting and untreated water when watering the plants and watering the grass.

    My only regret is I didn’t install this softener sooner.

    I have been very happy with this softener. It was easy install and set up. The data it provides and the home damage protection it gives me is just what I was looking for.

    The system quickly alerted me of a leak under my kitchen sink. This saved me time and money because I didn’t have to replace anything.

    I purchased the DROP system because the city water coming into my home has an orange tint at times and would taste horrible. The combination of a water softener and backwashing carbon filter has completely eliminated my problems.

    In the year my system has been installed it has identified problems with toilets at least 3 times. One toilet has a tendency of the flapper chain getting twisted and will run 2 gallons per minute continuously. Instead of wasting and paying for thousands of gallons of water, I’ve been able to correct that problem right away. It has also saved me a few times when I was adding water to the swimming pool and forgot about it.

    Our water is softer and our appliances are receiving better quality water to extend life. The remote features through the Drop Connect App. help us better understand water usage/waste and any potential problems. I like the ability to control the parameters for continuous flow warning notifications. I also like the ability to shut off the water remotely if needed. You just never know when something might happen. The leak detectors give peace of mind and wish to buy more. The leak detectors also give a location room temperature reading which I use often. I’m happy with the purchase.

    Two times a leaky toilet was identified. Cool technology. Also my swimming pool auto refill was stuck open, and I was alerted to continuous water flow and found the source before wasting too much water and money.
