WSP 150,000 Grain Whole House Water Softener - Commercial

Many whole-house softeners promise relief from hard water issues but fall short: they clog quickly, struggle with heavy use, or miss stubborn scale. The WSP 150,000 Grain Whole House Water Softener is built for continuous high demand, removing the minerals that cause scale, spots, and stiff laundry in large homes or commercial sites.

The frustration of hard water that outlasts your softener

You’ve tried water softeners before, but the scale keeps building on faucets and in the toilet tank. The dishes still come out spotted, soap barely foams, and towels feel rough after washing. Over time, the film on shower doors thickens, and you spend more time scrubbing appliances and surfaces. It’s clear the last system wasn’t up to the task, leaving you with ongoing chores and spotty results.

How the control head manages water use and saves salt

At the top of the system, a metered control head tracks exactly how much water you use. This means it only regenerates—flushes the minerals captured by the resin—when necessary, rather than on a set schedule. The digital display lets you see setup details and current status easily. The 1.5-inch ports allow higher flow for large or busy properties. This smart control helps reduce salt use and water waste, making the softener more efficient and less work for you.

Media designed specifically to tackle hardness

Inside the tank, standard mesh cation exchange resin captures calcium and magnesium, the minerals that cause hard water problems. This resin swaps those minerals for sodium, which doesn’t deposit scale. The high capacity means it can process a large volume of hard water before needing to regenerate. This targeted approach makes the softening effective and reliable over time.

A large, durable tank built to handle big demands

The tank measures 18 inches in diameter and 65 inches tall, holding about 4.69 cubic feet of resin. That size supports the 150,000-grain capacity, enough to meet continuous, high-volume water use without frequent regeneration. The heavy-duty construction is backed by a lifetime warranty on the tank itself, so you can count on it to last through years of service.

Best suited for commercial and multi-unit sites

This system fits locations with many simultaneous users, such as a multi-bathroom home or commercial space. Its large capacity and 1.5-inch porting accommodate multiple outlets running at once without drops in performance. If you have only a smaller household or lower water use, a smaller system would be a better match. For very large or industrial sites, a custom solution may be needed.

What you receive with this water softener

The WSP 150,000 Grain Whole House Water Softener includes the full tank and resin media ready for installation. A bypass valve is included so you can isolate the system from your water line during maintenance without shutting off water to the building. You’ll also get 10 feet of discharge hose for the drain line. The control valve and electronics come with the manufacturer’s warranty, and the pressure vessel tank carries a lifetime warranty.

At 150,000 grains of capacity this suits a commercial or multi-unit site - around continuous high demand with many outlets.

Sizing is a trade-off, not a target. Go bigger and it regenerates less often and uses less salt per gallon softened; go smaller and you will find the soft water running out before the next cycle. When in doubt, up. Send us your water test if you would like the sizing checked before you order.
