Water Softener

Your commercial water softener does more than you may realize. By removing the minerals from the water, the appliance can help prolong the life of your equipment. Removing the minerals can also have health benefits for your employees.

Keeping your commercial water softener functioning efficiently doesn’t take a lot of hard work. Some routine maintenance is often enough to prevent the need for expensive repairs. However, if you do need water softener repairs or a new unit, the professionals at CS Mechanical are here to help.

Water Softener Repair

Even with regular tank cleaners and system inspections, issues can still occur with your water softener. If you need commercial water softener repairs, CS Mechanical can help. Our technicians are familiar with and experienced in diagnosing and repairing various issues. Some common problems you may experience include:

  • Issues with the water softener’s settings. Sometimes, the water softener may not adequately display when it’s recharging, and this affects performance.
  • Salt bridges can form, creating air pockets that prevent the beads from recharging.
  • Excess water in the brine tank is another common issue affecting performance.

Clogs, dirty filters, and defunct resin beads are other issues our technicians typically repair. Sometimes, a motor failure occurs. While not common, especially with routine maintenance, the motor can still malfunction. If your water softener is making strange noises or sounds like it’s struggling to perform a cycle, call CS Mechanical to schedule a service appointment.

Commercial Water Softener System

A commercial water softener system is an important appliance. The water softener addresses hard water, common in San Antonio, that can damage industrial equipment, boilers, and even your HVAC system. The water softener removes the minerals that cause the damage.

While there are different commercial water softener systems, we most commonly see salt-based ion exchange units. This type of water softener comes with two primary parts.

  1. The brine tank, where the salt is stored and mixed with water, forming a brine solution
  2. The resin tank, where the water flows through at a rapid rate, flushing out the calcium, magnesium, iron, dirt, and sediment from the water

A meter tracks your water usage; you can often find it mounted on the side of the brine tank. Throughout the life of the water softener, you will need to regenerate the resin tank. How often depends on your water usage. Our technicians will help you track usage and plan a schedule accordingly.

Water Softener Salt

We recommend replacing the salt in your commercial water softener system at least once every five years. However, this depends on usage. Some businesses may need to replace the salt more frequently. During our inspection of your water softener system, we can recommend a schedule to help ensure optimum efficiency.

During the routine cleaning, we will scrape the old salt off the tank walls. This is the best time to add new salt. We can also show you how to check the salt levels so you know when it’s time to add more in-between inspections.

If you’re interested in learning more about replacing your traditional salt with Potassium Chloride, we can explain the benefits of the low-sodium alternative. One of the benefits is the reduced impact potassium chloride has on the environment.

Water Softener Installation

Even though you can find plenty of online guides, we don’t recommend turning a commercial water softener installation into a DIY project. Even though the process is relatively simple, it’s still best left to the professionals. Remember, you are connecting an appliance to your building’s water lines, and a simple mistake can result in flood damage. Instead of risking the chance of additional repairs, let CS Mechanical handle the installation of your commercial water softener system.
From installing the valves and connecting the drain tubes to starting the system, our licensed and experienced technicians will take care of every aspect of your water softener installation project. We always run a backwash cycle to ensure the system functions efficiently. During the backways cycle, we’ll also check for any levels. We will also check water levels in the brine tanks and make any adjustments per the manufacturer’s instructions.

If you have an existing water softener system, we’ll also remove the old appliance.

Climate Considerations

The weather can affect the efficiency and lifespan of your commercial water softener system. Freezing temperatures, while uncommon in San Antonio, can result in frozen pipes. If the pipes burst, damage from flooding is common. To avoid this problem, we’ll install your water softener in a protected location. If necessary, we can also move an existing water softener to a more ideal location.
Water softeners can also negatively impact the environment. This can be especially true for salt-based systems. If you’re ready to switch from a salt-based water softener, we can make recommendations. We can also install your new water softener system. To minimize the water softener’s environmental impact, we recommend scheduling routine maintenance. We can create a maintenance schedule that will help keep your water softener working efficiently.


Scheduling routine maintenance for your commercial water softener can reduce the number of necessary repairs and prolong its lifespan. Most commercial water softener systems last anywhere from ten to fifteen years with regular maintenance. We recommend having your commercial water softener cleaned once every five years.

You’ll notice a difference in efficiency, along with the appliance’s performance. Your skin and clothes will feel cleaner, and you’ll also find you’re using less soap. For businesses like hotels, restaurants, and dry cleaners, this can result in better service and a reduction in some operating costs.


How does a commercial water softener work?
Commercial water softeners use ion exchange to remove calcium and magnesium ions, which cause water hardness. Water passes through a resin bed where these ions are exchanged for sodium ions, softening the water. Periodically, the resin bed is regenerated with a brine solution to flush out the accumulated minerals.
What are the benefits of installing a commercial water softener?

Installing a commercial water softener provides numerous advantages for businesses. Firstly, it prevents the accumulation of scale in pipes, appliances, and industrial equipment, reducing maintenance costs and prolonging their lifespan. Additionally, softened water improves the efficiency of appliances like water heaters and dishwashers, leading to energy savings and lower utility bills. Moreover, using softened water requires less soap and detergent, resulting in cost savings and environmental benefits. Overall, a commercial water softener ensures better water quality, extends equipment durability, enhances operational efficiency, and promotes sustainability in business operations.

How often should a commercial water softener be serviced?
The frequency of servicing for a commercial water softener depends on factors like water hardness, usage levels, and manufacturer recommendations. However, a general guideline is to have the system inspected and serviced at least once a year. This includes checking the resin bed, replenishing salt levels if necessary, and ensuring all components are functioning correctly.
