Most likely the DI Resin needs to be changed. After enough filtration, the Resin loses efficiency and requires a change once the system shows signs of TDS.

• If the DI resin has already been changed, then ensure the cartridge is packed tight and seated properly inside the housing with the O-ring facing upward. Apply lubrication to the O-ring for a more effective seal.
• If the issue persists with brand new filters, further troubleshooting may be required to determine the source of the issue. Reach out to us so we can help.

There are many reasons for this to occur. This can range from source-water conditions, temperatures, hose sizing, and filter conditions to name a few.

SOURCE WATER CONDITIONS

This refers to any factors that are  affected by the hose spigot used to provide water to the machine. The system is at the mercy of how much water pressure the spigot can create. Commercial buildings have stronger water sources than typical residential well jobs, a difference may be noticed depending on job location. 

If insufficient water pressure is present, a booster pump may be used to boost incoming pressure to the system.

***Ensure proper hose size is used for the incoming water (¾” or ⅝”) for efficient system flow. ⅜” is not sufficient.***

WATER TEMPERATURE

The temperature of water has an effect on water flow. Colder water will result in slowed flow, warmer water will do the opposite. In transitional seasons (Spring / Fall) you may notice changes in flow compared to the Summer time.

Ground water temperatures take time to adjust to the season. During the Spring, water flow may be noticeably lower than the Summer (especially during residential work) as the ground is still warming up. It may be wise to boost source flow during these conditions.

Freezing Conditions are no condition to use this system.

These systems are not designed for Winter use. Freezing temperatures will result in constriction, and ultimately damage the internal structure, resulting in poor performance. Proper storage in a heated environment will prevent damage. It is best to change all filters if the system has frozen. 

FILTER CONDITIONS

When a noticeable change in flow is observed (with the factors mentioned above taken into consideration) it may be time for a pre-filter change. Some systems use more than one pre-filter combination, which we advise changing both simultaneously for consistent and efficient filtration. 

With any filter, ensure proper fitment of cartridges is achieved. Poor seals / placement can affect system performance. Filter O-ring seals face upward and require lubrication for maximum efficiency. 

There could be a few factors at play here. These issues are usually attributed to the amount of resin used to refill a cartridge or the quality of resin used.

Proper refilling and placement of a DI cartridge is key to resin performance. A half filled cartridge will not properly filter and will result in undesired TDS and another resin change. Pack as much resin into the cartridge so that it is nice and tight to ensure the proper resin level is achieved.

• Resin age and quality is an important consideration. Resin from 3rd parties may not be the right fit for the system. It may cause TDS issues and more resin changes that could have been avoided. Make sure your resin is properly stored in a temperature controlled environment to avoid any premature expiration. 

We have replacement parts available for warranties involving damaged fittings and systems. Fill out a warranty form and we will assist you with what you need. Filters and items damaged by freezing conditions are not covered by warranty.

A common cause of leakage at the inlet connection point of the system is due to the internal gasket on the hose fitting. Be sure that it is snuggly in place, isn't damaged, and is the correct size. If any of those aren't true, pick up a replacement and you'll have a leak free system again.
