The WECO Hybrid filter is a Point-Of-Entry (POE) filtration/softener system for municipal water supplies. The softener uses a high-efficiency 10% cross-linked gel type strong acid cation resin with a high resistance to oxidation, osmotic and thermal shock. WECO water softeners can be used with chlorinated municipal water without fear of premature resin break-down. The main application of this filter system is water softening for well and municipal water supplies. The WECO system is compatible with residential, industrial, institutional and medical water supplies. This water softener can be used stand-alone or in conjunction with other WECO filtration systems. Other applications for this filtration system are:

  • Hardness removal for reverse osmosis systems
  • Whole house water softening
  • Water softening in apartment buildings
  • Laundry water conditioning
  • Industrial demineralization (H+)


WECO water softeners are available in a variety of sizes. Please consult with WECO Technical Support for assistance in selecting the proper size filter to meet your water purification requirements.


Hard water is the result of excess calcium and magnesium minerals in the water supply. The calcium and magnesium (hardness minerals) dissolved in the water can cause a variety of problems ranging from aesthetic issues to serious plumbing damage. Hard water causes unsightly spotting on glassware, plates, silverware and cooking surfaces. High water temperature causes hardness minerals to collect on the bottom of the water heater tank. Eventually the water heater will make less hot water because it is partially filled with mineral particles instead of water. This also reduces the efficiency of the heating element, costing more energy dollars every day. Hard water also damages the heating elements in coffee and tea makers. The solid mineral deposits will clog filter screens in dishwashers, refrigerators, ice makers and commercial beverage dispensing equipment. Hard water also reduces the effectiveness of dishwashing detergents, making dishes harder to clean by hand and in the dishwasher.



Hard water is softened by removing the calcium and magnesium it contains. When hard water passes through the softening system's resin bed, the calcium and magnesium (hardness) ions are removed through an ion exchange process, so only softened water passes through to your home or business. Once the resin bed fills up with hardness ions, it must be regenerated to remove the calcium and magnesium (hardness minerals) on the resin. Salt is typically used in the regeneration process and restores the resin to an active state so the ion exchange process can begin again. Sodium chloride or potassium chloride softener salts can be used to regenerate the WECO line of water softeners. The ion-exchange resin can also be regenerated with acid to put the resin in the H+ form.


The WECO water softener consists of a Structural Poly Glass™ pressure tank and a Fleck 5810 XTR2 touch screen controller. Structural Poly Glass™ is the ideal filter media tank for residential and industrial water filtration and conditioning duty. The pressure tank has an attractive stainless-steel outer jacket for good looks, and durability. This combination provides unmatched strength and chemical resistance for years of trouble-free service. The slim diameter makes installation easy in tight locations and does not take up a lot of floor space. The Fleck XTR2 controller is constructed of a fiber-reinforced polymer valve body for superior strength and durability. It is non-corrosive and UV-resistant. The controller uses an optical sensor for precision cycle positioning. The controller is easily programmed and user-friendly due to detailed screen descriptions, color LCD display, and familiar icons. The intuitive navigation is easy with a large LCD screen. The controller has an internal memory that remembers your settings during a power failure. It has a convenient Vacation Mode to save water when not in use. The password lock-out prevents unauthorized users from changing the settings. An audible alarm sounds if there is a controller error. Diagnostics can be downloaded via USB should the need arise. The Fleck XTR2 controller has feature rich diagnostics including:

  • Current Flow Rate
  • Peak Flow Rate (can be reset)
  • Totalizer (can be reset)
  • Last Regeneration
  • Daily usage for last four weeks
  • Software Version
  • Number of Regenerations
  • Regeneration Interval
  • Usage since last regeneration
  • Last program change


Water enters the top of the tank through the Fleck control valve and passes downward through the water softening resin. The WECO water softener will clean itself periodically by rinsing away solid impurities that can plug the resin bed. The control valve automatically starts the backwash process. The backwash procedure is an operation where water passes backward through the filter media at a fast flow rate. It enters the tank at the bottom through the riser tube, then flows upward through the filter medium, exiting at the control valve and sent to waste. The rapid, turbulent upward waterflow, in addition to flushing away particulate matter, loosens and resettles the media bed. A regeneration cycle flushes the resin bed with brine to strip off water hardness ions and load the resin’s exchange sites with sodium or potassium ions, preparing it for another filtration cycle. The treated and conditioned water enters the riser tube at the bottom of the resin tank, passing upward and exiting the filter through the control valve. Acid can also be used to regenerate the resin for industrial applications.
