WSP 500 GPD Whole House Reverse Osmosis System - Commercial, Light

Why it's happening

Your water picks up dissolved solids from natural sources underground or during treatment at a municipal plant. These can include minerals like calcium and magnesium, plus other compounds that don’t settle out easily. The best way to confirm is a Total Dissolved Solids (TDS) test, which measures the combined content of all dissolved substances in your water. A high reading means you’re dealing with more than just “hard” water.

What it’s costing you to leave it

Leaving dissolved solids untreated affects more than taste. Appliances and fixtures can develop scale and deposits that reduce efficiency and lifespan. You may need to use more soap or detergent to get your dishes and laundry truly clean. Over time, these deposits can stain surfaces and leave residues that become harder to remove, costing you time and effort.

How this system fixes it

The WSP 500 uses reverse osmosis, a process where water is pushed through a special membrane that blocks dissolved solids and contaminants but lets clean water through. Think of it as a filter fine enough to separate out tiny particles dissolved in the water. This improves taste and reduces many common impurities before the water reaches your tap or processes.

What this system can handle

Built for light commercial use, this system treats up to 500 gallons per day—enough for small businesses or homes with high water needs. It performs well under varying water conditions and works alongside pre-filters that protect the membrane by removing larger particles and chlorine. This setup helps reduce scale buildup and protects equipment downstream, making it a reliable choice for consistent water quality.

What you actually get

This system includes the reverse osmosis membrane and necessary pre-filters configured to optimize filtration. The exact setup is confirmed when sized for your water, ensuring it meets your specific water quality and volume needs. Installation requires your local licensed plumber, as the system ships ready to fit into existing water treatment setups.

Is this the right size for you

If you need a system that handles several hundred gallons daily and want to improve taste and reduce dissolved solids reliably, this unit suits you. For smaller households or lower daily use, a smaller system might be more appropriate. Conversely, if your water demands exceed 500 gallons daily, you’ll want to consider a larger capacity system.

Living with it

The system requires regular maintenance, including timely replacement of pre-filters and membrane cleaning or replacement as advised by water quality and use. While not frequent, this upkeep is essential to maintain performance and prolong system life. Your plumber or water treatment professional can help schedule and perform routine servicing.

What it won’t do

This system reduces dissolved solids and many common contaminants but does not address bacteria, viruses, or certain chemical pollutants without additional treatment steps. If you need comprehensive microbial protection or removal of specific industrial contaminants, other specialized systems or treatments would be necessary.
