The Everyday Series 48,000 Grain Capacity Tier1 Water Softener is the complex water treatment solution your home needs. The Tier1 Resin reduces calcium and magnesium minerals in your water to reduce the damaging effects of scale build-up that can cause damage to your pipes and clothes and the early failure of your water-using appliances. These retained particles are then washed down the drain during the system regeneration cycle to minimize their exposure to your skin, hair, faucets, food, and pipes. Enjoy cleaner dishes, brighter laundry, and smoother hair that softened water can provide. This system features an easy-to-use LCD control valve head which allows maneuverable setting and monitoring of critical operational information. Want to know more?

Grains of Hardness

When a water softener is referring to 'grains' it's talking about how many grains of hardness it can process before regenerating. Grains of hardness processed depends on how large your household is, as well as how hard your water actually is.

For example, a family of 4 with 20 grains of hardness: Your family of 4 will use approx. 300 gallons of water per day (4 people x 75 gallons per person). Since the water has 20 grains of hardness, you'll need to treat 6,000 grains of hardness per day (300 X 20). Water treatment capacity = (48,000 x .75) divided by 20 = 1,800. Your system will regenerate after about 6 days (1,800/300). ((48,000 grain capacity x 75% capacity)/ 6,000 grains per day).

Frequently Asked Questions

How much is the Max. Hardness of the Water (in GPG)? During set-up, the customer customizes the regeneration cycle based on their water hardness level

How much is the max. Clear Water Iron Removal (ppm)? An iron filter is recommended for iron levels above 0.3ppm

Is it Demand Initiated or Timed? The WS-165-150 is demand initiated, the control valve features a water use probe (impeller), which measures water use

How long does the Regeneration Cycle take? Two hours

Will I experience a disruption in water service during the Regeneration Cycle? Yes, there will be a disruption to water service during this time. Most of our customers schedule the Regeneration Cycle for 2:00 AM, ensuring there are no conflicts. If a disruption in water service during the Regeneration Cycle is an issue, select the Tier1 Automatic Bypass Control Valve water softener!

How much salt do I use in the 100L square brine tank? We recommend using no more than three 40 pound bags of water softener salt

What is in the mineral tank? The system arrives to you pre-filled, ready for use with Cation Exchange Resin 7%

Does it have an indicator to notify me about low salt? No

What if my home is plumbed with PEX or CPVC supply tubing? Homes plumbed with PEX or CPVC supply tubing may require the use of compression fittings, such as the Sharkbite® brand. Due to varying sizes and configurations, compression fittings are not included with the water softener. If these fittings are required, they can be purchased for a reasonable price at most hardware stores.

Installation Guide


  1. Test Resin Tank - the tank will have a temporary shipping cap, a master O-Ring, and a piece of tape covering the riser tube. The cap, master O-Ring (another is supplied) and the tape must be removed and discarded prior to attaching the control valve and the upper distributor. This water softener includes regular control valve connections and a bypass valve connection; therefore, a set of installation components has been included for each method of installation. As such, following installation, the installer will be left with an “extra set” of installation components (animated connectors, brine line flow control, master O-Ring, washers).
  2. Read the installation guide provided above.
  3. Unpack the Tier1 Everyday Series WS-165-150 and ensure all parts pictured and listed above are present. Rotate the shutoff valve at the main water line to the OFF position
  4. Shut off the power supply to the water heater – only if you will be draining the tank
  5. Open the highest and lowest water faucets in your home (drainage and pressure allowance)
  6. Ensure you are aware of local laws and codes regarding the installation, use, and maintenance of water softeners
