Product Overview

Highly rated by users, the Fleck BWF-CRB15-56SXT Digital Carbon Backwashing System

is a versatile and effective carbon backwashing filter system. Whether you need to remove chlorine from your well water, or remove bad odors like hydrogen sulfide, the Fleck Digital Carbon Backwashing system delivers quality water treatment with little maintenance required.

Each unit includes a standard ¾” bypass valve made of durable stainless steel, but you can request 1” if needed. In a household or office with 3 – 8 GPM, the structural resin tank effectively removes or reduces a number of contaminants from your water, including pesticides/herbicides, THM, MTBE, and organics. 

The digital controller is fully automated, which means once you set the backwashing cycle, you never have to do it again. During the backwashing process, harmful residue is flushed out of the backwashing filtration media and cleans the carbon for continued clean drinking water. 

The 1.5 high activity carbon media is GAC (granular activated carbon)  which is what makes it so effective at removing chlorine. The backwash cycle comes already programmed, but you can adjust it based on the level of contamination and water usage in your home. 

Depending on these criteria, backwashing every 5 – 7 days on average in a household using 2000 gallons/day should keep your Fleck Carbon Backwashing System running for years. The resin tank is covered by warranty for 10 years (mfg conditions) so you can rest easy once you install it, knowing that your investment is protected for a long time.

Product Overview:

For those of you who are concerned about the presence of silica and other harmful minerals in your well or municipal water, the WECO Backwashing Filter with A600E Anion-Exchange Resin is specifically built for reducing alkaline and nitrates in your water.

These are industrial-grade ion-exchange backwashing filters. Unlike backwashing carbon filters, anion-exchange uses insoluble, high-grade polymers instead of carbon. The polymers are porous, allowing them to absorb more ions in a larger surface area. The result is clear, clean water free of harmful minerals.

The Weco Backwashing Filter uses a user-friendly Fleck 5810 XTR2 digital controller with advanced diagnostics features, remote regeneration, and programmable auxiliary relays. The resin tank is secured by a stainless steel jacket and uses standard 1” bypass valves for connecting to your well or city water supply.

Water Softener Vs Backwashing Filter System

As a homeowner struggling to find the right water treatment, you may be slightly confused about the difference between a whole house water softener and a backwashing filter system. There is a quite a significant difference in price between the two, and they both are designed to treat water, but in different ways.

A water softener is best used when you’re dealing with hard water issues. Water softeners can remove high levels of calcium and magnesium, as well as chlorides and ferrous elements. But over time, the resin tank accumulates residue from all these chemicals that can re-enter your water.

How A Backwashing Filter System Works

The resin beads in your water softener unit can be recharged with ordinary table salt but this doesn’t entirely remove trace remains left behind in the resin tank. Backwashing filter systems solve this problem, greatly extending the life of your water filter system and reducing your maintenance time to practically zero.

  1. Made of highly charged carbons that adsorb unwanted chemicals, a media filter is fitted inside the resin tank.
  3. During regeneration, the flow of water is reversed, and the media filter inside the tank is flushed with the backwater.
  5. A digital controller with a bypass valve is attached to the resin tank. The controller can also be purchased separately as a replacement if necessary.
  7. The controller can be programmed to activate the backwash cycle according to your schedule. When it activates, the bypass valves adjust to keep water flowing in your home even while the filter and resin tank is being cleaned.
  9. By reversing the flow of water, the media filter is cleaned, thereby removing the unwanted residue.

Backwashing filter systems are designed to remove specific elements. The media filter is made of special material which works best when used to remove specific elements. Fortunately, there are a wide range of backwashing systems to handle most water treatment issues.

Water Softeners

  • Uses salt-charged ion resin beads to absorb calcium and magnesium in hard water
  • Water must be turned off when being serviced
  • Resin tank requires routine regeneration manually
  • Generally much less costly than a backwashing filter system

Backwashing Filter Systems

  • Uses a thick media filter charged with carbon to clean resin tank of unwanted residue
  • Removes specific elements such as iron, chlorine, chloramines, alkalines, nitrates or other harmful particles 
  • Programmable digital controller for timed regeneration
  • Bypass valve allows for water use while the filter is being serviced
  • Resin tank does not need to be serviced as often
  • Requires little maintenance
  • Lasts longer than a water softener

Types of Backwashing Filters

The first step to choosing the right backwashing filter is knowing what type you actually need. Depending on the contaminants in your water, you’ll want a backwashing filter designed specifically for removing the most harmful pollutants in your drinking water

Granular Activated Carbon Backwashing Filters

A special kind of charcoal with high adsorptive properties with increased surfaced area. A filter that uses granulated activated carbon improves water taste and odor, and is best for removing the following contaminants:

  • Chlorine
  • Organics
  • Pesticides
  • Detergents 
  • Sediment

Catalytic Carbon Backwashing Filters

Uses a special type of activated carbon ion carbon to remove the following:

  • Chloramines
  • Hydrogen sulfides 
  • Organic compounds 
  • Trihalomethanes (THMs)

Catalytic Granulated Activated Carbon (GAC) Filter

Similar to granulated activated carbon, it’s made from coconut shells and is extremely effective for removing the following water contaminants:

  • Chlorine
  • Chloramine
  • Iron
  • Sulfur
  • Manganese 

Catalytic GAC filters can also be used as an oxidizer.
