A dual-purpose whole-home water treatment system that delivers soft water while filtering out municipal chlorine and chemical contaminants. Manufactured in Barrie, Ontario by Excalibur Water Systems, the Chlor-A-Soft™ Series solves the two most common problems in Canadian city water: limescale hardness and chlorine disinfection byproducts. By blending high-capacity ion-exchange softening resin with premium catalytic activated carbon media in a single high-efficiency tank, it softens water for your plumbing and appliances while removing chlorine, chloramines, volatile organic chemicals (VOCs), and unpleasant chemical tastes and odours from every tap in your home.

Key features
- Dual-action softening and carbon filtration — combines premium softening resin and catalytic activated carbon in one tank to eliminate hardness scale while neutralizing chlorine and municipal chemical additives.
- On-demand metered regeneration — computerized electronic control valve tracks household water consumption and initiates regeneration cycles only when the media bed requires cleaning, conserving water and salt.
- Chlorine and chloramine reduction — catalytic carbon layer adsorbs chlorine, chloramines, trihalomethanes (THMs), and volatile organic compounds to improve drinking water taste and protect skin and hair from drying out.
- High-flow distribution valve — engineered with large internal ports to deliver robust water volume with minimal pressure loss across multiple simultaneous showers and fixtures.
- Power-loss memory protection — integrated capacitor power cell preserves time-of-day clock and programmed regeneration settings through electrical power disruptions without battery replacement.
- Heavy-duty chrome-jacketed tank — fiberglass composite mineral tank wrapped in a protective chrome outer jacket for corrosion resistance and a clean mechanical room aesthetic.
Capacity and sizing
The Chlor-A-Soft system is engineered specifically for municipal water supplies and is available in three residential capacities based on home size and water demand:
- 30,000 Grain (EWS SPREF30) — recommended for 1 to 3 person households, condos, or townhomes with standard city water hardness and 1 to 2 bathrooms.
- 45,000 Grain (EWS SPREF45) — standard sizing for family homes with 3 to 5 occupants and 2 to 3.5 bathrooms, balancing softening reserve with high carbon contact time.
- 60,000 Grain (EWS SPREF60) — high-demand capacity for large families, executive residences with 4+ bathrooms, or households with exceptionally high daily water usage.

Before you buy
- Municipal water focus: This system is specifically designed for chlorinated or chloraminated municipal water supplies. For unchlorinated private well water with high sulfur or manganese, consult an AVL specialist for dedicated filtration configurations.
- Main water line connection: Install on the main cold water supply line after the water meter and before the water heater, ensuring an accessible location for the bypass valve.
- Clearance and drainage: Locate within 1.8 m (6 ft) of a 120 V electrical receptacle and near an approved drainage discharge (floor drain, laundry tub, or standpipe) maintaining an air gap.
- Outdoor hose bibbs: Where possible, isolate irrigation and exterior hose bibbs from softened water lines to conserve salt and treated water.
- Salt selection: High-purity compacted salt pellets or solar crystals are recommended. Potassium chloride may be used as an alternative regenerant.
- Professional installation: Plumbing connections must comply with provincial building and plumbing codes and should be completed by a licensed trade professional.

Frequently asked questions
What makes the Chlor-A-Soft different from a standard water softener?
The Chlor-A-Soft is a dual-media system featuring high-capacity softening resin paired with premium catalytic coconut-shell activated carbon. It simultaneously softens hard water and removes chlorine, chloramines, bad tastes, and chemical odors in a single tank.
Why is municipal chlorine removal beneficial for homeowners?
Chlorine and chloramines added by municipal water treatment plants can dry out skin and hair, degrade plumbing rubber O-rings, and damage high-efficiency softening resin over time. Removing chlorine provides odorless, spring-quality water throughout the entire home.
How does the metered control valve optimize regeneration cycles?
The computerized digital control valve monitors actual water usage down to the liter and regenerates on-demand based on consumed capacity rather than a static timer, reducing salt and wastewater volume.
What size household is this combination unit designed for?
The system provides softening and chlorine filtration for households with 2 to 6 people with municipal flow rates up to 12 GPM (45 L/min) without noticeable water pressure drops.
Does the activated carbon media need separate replacement?
The high-grade catalytic carbon media has an extended service life of 5 to 7 years in typical residential municipal water conditions before media re-bedding is required.
What plumbing pipe diameter connects to the bypass valve?
The unit includes a commercial-grade 1-inch full-port bypass valve with quick-connect union fittings that connect directly into 3/4-inch or 1-inch copper or PEX plumbing lines.
What electrical supply is needed for the control valve?
A standard 120 V 60 Hz unswitched wall outlet powering the included low-voltage transformer.
Can the Chlor-A-Soft be installed in basements with floor drains?
Yes. Connect a 1/2-inch drain line with an approved vacuum breaker/air gap to an open basement floor drain or utility sink to discharge regeneration rinse water.
How does the tank construction protect against condensation?
The dual-media resin tank features a polished chrome exterior jacket that protects against corrosion and limits exterior condensation sweating during humid Ontario summer months.
How often should salt be checked in the brine tank?
Inspect the brine tank once per month and ensure salt pellets remain above the brine water level, adding high-purity solar or evaporated salt pellets as required.
