The WSP50ARB spin-down sediment filter is a central water purification pre-filter to protect your terminal equipment and appliances such as downstream pipelines, water purifiers, water heaters, wall-hung boilers, dishwashers, washing machines, and showerheads. 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. An integrated Auto Flushing Module enables the system to flush automatically on a preset schedule. Use the HD touch screen to adjust flushing frequency, ranging from 1-99 days, and flush runtime(choose from 15, 30, 45, 60, or 90 seconds). Thanks to its size(nearly double the size of our WSP50 series) and auto flushing module(easy maintenance),WSP50ARB takes water purification as well as plumbing and appliances protection to the next level.
The WSP50ARB filter is self-cleaning and reusable. A toggle switch allows particles and contaminant buildup trapped in the filter to be flushed out without having to shut down the water supply first. The system is preset to flush for 15 seconds every 15 days.
It is recommended to flush at least once a week for 30 seconds each time, depending on the water usage, sediment amount, and the hardness level in your source water. It is recommended to clean the filter cartridge after it has been used continuously for 8-12 months. Simply remove the stainless steel filter mesh and clean it with a brush or soak it in vinegar.

Install the system in a dry indoor environment away from heat sources. To achieve ideal water filtration results and build ultimate protection for plumbing equipment and appliances, consider adding a Water Softener/Descaler, a Whole House System, and a UV Water Filter. 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.
