Why Siliphos?

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

High-quality Materials

WSP Series utilizes 316L food-grade stainless steel and has passed the explosion-proof test over 500 psi pressure and the water hammer test over 100,000 times.

Prolong Service Lives of Your Appliances

WSP Series is your reliable choice of pre-filters. 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, water filtration, and expensive appliances.

Easy Installation and 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 a 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.

Choose the Appropriate Microns of Filters for Your House

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.

Please avoid the mistake of using 'fine' filters for 'rough' water and causing the filters to clog sooner than expected.

Use multi-stage filters to achieve one of the best filtering results and longer cartridge life.

Easy install and very sturdy product.
The unit installs easily and is impressive. The heavy duty design is preferred over other products I’ve seen for this use. Only wish that the valve handle was made of metal. It’s a bit hard to turn but Laurence in customer service was extremely helpful in addressing this concern. Performance has easily met my expectations.

Excellent product. Easy to install, so as long as you preplan the pipe route. This has improved the water quality and customer service is quick to respond if I have a question that needs to be resolved, specifically JOHN.

I added an additional bone char filter to eliminate fluoride for the entire house and have two come to support this brand and have recently bout two shower head mineral filters and a reverse osmosis under the sink filter.

Since having this product I only had one defect which would include a broken carbon filter which was most likely broken by the delivery driver but a quick email and a replacement was sent without any hassle.

5.0 out of 5 stars Goodbye sediment - Hello clean water
Reviewed in the United States on October 5, 2023
Currently working to re-plumb my entire house and figured some better filtration was needed. I chose this reusable sediment filter and couldn't be happier. Unit itself is very solid and the filter is offered in a variety of micron levels to best meet the needs. When it does start to get dirty or plugged, the filter can be back-flushed or removed and cleaned for extra longevity at no extra cost. Includes the mounting bracket which made installation a breeze. Add your inlet and outlet fittings along with a couple of shut-off valves and your pretty much done.

A big shout-out to Nick in the customer support department too. I had a couple of post-sale questions regarding the unit I had purchased, and Nick was great in responding quickly and answering all of my questions. This level of support is getting increasingly rare nowadays, so getting a quick response from Nick was greatly appreciated.
