The Waterdrop WD-PFA full-automatic backwash spin-down sediment filtration system can be considered as a household’s first line of defense. It is equipped with an integrated back washing technology that flushes the filter automatically and prevents clogging, even after prolonged use. It sports a 40-micron pore size stainless-steel mesh that intercepts parasites, rust, sand, and other harmful impurities before they get to your water appliances. This helps to extend the lifespan of your water-related appliances. It has a 20 gallons per minute flow rate – large enough to serve the entire household. The lead-free copper connector is very durable and can resist crack, explosion, or extreme temperature. The food-grade housing is safe to use. Installation is seamless – you get multiple connecting options to conveniently connect the system to various water pipe sizes in your home.

Product Details:

  • This Filter System Works With Whole-house Water Filtration Systems, Undersink Water Filtration Systems, and Ro Systems.
  • Automatic back washing: Waterdrop WD-PFA whole house water filter doesn’t require manual flushing to work. It features an innovative automatic flushing function, saving you time and stress while ensuring your water filter is flushed automatically. You can choose 7, 15, or 30 days as an automatic flushing interval period. If needed, you can flush the system instantly by simply pressing the button. This ultimately prevents the clogging of the filter mesh.
  • The first line of defense: The durable stainless steel filter mesh resists corrosion. The 40-micron pore filter size allows the sediment-water filter to effectively intercept large particles, such as sand and rust, protecting your home’s water supply.
  • Prolongs water facilities' lifespan: As the first line of defense for your home’s water filtration system, the sediment filter protects your pipe from rusting and prolongs your home water pipes and appliances’ lifespan. It also makes them more efficient; for example, it enables your dishwasher to provide even cleaner dishes.
  • Break-free and explosion-proof housing: The housing is made from food-grade materials. It has been tested under 400 psi pressure without crack or external dent whatsoever. The reinforced construction is quite durable.
  • Include multiple components: Two push-fit plumbing fittings come with the spin-down sediment filter, thus you don’t have to extra purchase it. We provide you with four types of screw threads to connect: 1“MNPT,3/4” MNPT,3/4“FNPT, and 3/4” push-fit plumbing fitting. Three built-in AAA batteries last up to one year.
