The 48,000 Grain Capacity Tier1 Water Softener and 5 Stage Reverse Osmosis Drinking Water Filter System Kit is a convenient bundle that pairs a high-class water softener with a top of the line 5 stage reverse osmosis kit. The 48,000 Grain Capacity Tier1 Water Softener offers a hard water combating solution which uses anion charged resin to capture and reduce calcium and manganese that would otherwise contribute to scale build-up. By protecting your home from scale, the effectiveness of soaps and detergents is enhanced and you help protect your pipes and appliances from lowered efficiencies and early mechanical failure. The Reverse Osmosis system kit includes the under-sink system and matching cartridges and 4 glass bottles to use at your leisure. This system can deliver up to 50 gallons of filtered water per day and provides great tasting clear water on demand. The system starts with sediment and carbon filters to reduce large particles and contaminants, then runs water through the RO membrane which separates and rejects more threatening contaminants like barium, cadmium, chromium (III and VI), copper, fluoride, lead, mercury, nitrates, nitrites, radium, selenium, and total dissolved solids (TDS), sending them down the wastewater drain. After this process, water is stored in the RO tank and fed through a carbon filter one last time to remove displeasing taste and odors before finally reaching your glass. By combining a whole house system to protect your home and a water refinement point of use system to enhance your drinking water you can rest assured that Tier1 is protecting every drop.

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). If you give the softener its full dose of salt, 15 lbs. per cubic foot, you can go about 7-1/2 days before regenerating (45,000/6,000).

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 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 130L 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 8%

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.
