About this item

WSP Series:

  • WHOLE HOUSE PROTECTION: Serves as the first line of defense for your home's plumbing system. The 50-micron food-grade stainless steel mesh effectively intercepts sediment, rust, dirt, sand, and large particles before they reach your appliances. Ideal for protecting washing machines, water heaters, and finer water filtration systems.
  • FLUSHABLE & REUSABLE: Unlike traditional sediment filters that require frequent replacements, the WSP-50 is designed for longevity. The spin-down design allows for easy cleaning; simply open the purge valve to flush out trapped impurities. Regular flushing maintains performance and significantly extends the lifespan of downstream filters, saving you money on maintenance.
  • SAFE & RELIABLE MATERIAL: Built to last with a solid, lead-free brass machine head and a durable stainless steel filter screen. The high-quality construction withstands water pressure ranges of 20–100 psi and temperatures from 40–100°F. The transparent housing provides clear visual monitoring, so you know exactly when it’s time to flush.
  • EASY INSTALLATION & COMPATIBILITY: Features versatile double-threaded connectors: 1-inch MNPT and 3/4-inch FNPT on both ends to fit various plumbing setups. Includes a garden hose barb fitting for the flush-out valve. (Note: For strictly indoor use only. Avoid direct sunlight to prevent algae growth).
  • 50 MICRON RATING: This model removes particles down to 50 microns. It is ideal for municipal water or well water with larger sediment. NOTE: If your water source contains high levels of fine sediment or silt, the screen may clog quickly. In such cases, please contact us for advice on different micron sizes (e.g., 100, 200, 500, or 1000 microns) to best suit your water quality.

WSPSL Series:

  • Includes Siliphos to help soften water and prevent scale and stop corrosion, greatly extending the life of your plumbing fixtures. It is recommended that the filter to be replaced every 3-6 months to prevent scale from building up
Introducing WSP Series

The WSP series spin down sediment filter is the first line defense to your appliances. It protects and extends the life of your standard filters by removing the large dirt, sand, and rust particles before they reach the rest of your plumbing system, including water softeners and expensive appliances.

Easy Maintenance

The WSP series is flushable and reusable. It is recommended to flush it regularly (daily or weekly), depending on the water usage, sediment amount and the hardness level. However, as hardness tends to form hard scale that clogs the screen, simple flushes may not be sufficient. When necessary, remove the stainless steel cartridge and clean it with a brush and/or soak it in vinegar.

Why Siliphos

  • Siliphos is a water treatment compound, Polyphosphate, originates from the milk thistle seed.
  • Siliphos prevent ‘brown’ or ‘red’ water; eliminates hardness scaling.
  • It also stops corrosions of plumbing and bathroom fixtures.
  • All components used in Siliphos are pure food grade materials.
  • Siliphos is colorless, tasteless and odorless in the concentrations recommended for treatment.
  • Siliphos forms a thin protective layer on the inside of pipes.
Note

Water softeners and whole house systems usually do not lower the TDS level of the water. An additional Reverse Osmosis system may be necessary for your drinking water. Please consult iSpring professionals prior to purchase if you are unsure of which product will meet your needs.

Make The Right Choice

Filtration guideline

The WSP spin down sediment filter comes with a variety of options in micron size.

Smaller microns allow less through, but to get most life and efficiency out of your filters it’s important to only go as small as you need. Differences in water quality and your water pressure affect the performance of the WSP.

So contact our product specialist to get one of the best product recommendations based on your unique situation.

  • 50 micron /w Siliphos (Replace every 3-6 months)
  • 100 micron /w Siliphos (Replace every 3-6 months)
  • 200 micron /w Siliphos (Replace every 3-6 months)
  • 500 micron /w Siliphos (Replace every 3-6 months)
  • 1000 micron /w Siliphos (Replace every 3-6 months)
  • Please avoid the mistake of using 'fine' filters for 'rough' water and causing the filters to clog sooner than expected. Well Water may start from 500 to 50 micron, while city water can start from 50 to 5 micron. Choose the right filter cartridges with different micron ratings and filter media depending on source water quality and contaminants.
  • Use multi-stage filters to achieve one of the best filtering result and longer cartridge life.
