Waterway Crystal Water Cartridge Filter 325 Sq. Ft. (570-0325-07)

 Waterway Crystal Water cartridge filter offers a superior choice for easy maintenance and crystal clear, clean water. The filter is a chemical-resistant fiberglass-reinforced polypropylene tank for exceptional strength and long life. This filter has 2-1/2" internal piping, improves flow, and reduces system noise when in use. It also has 2-1/2" Valve Bulkhead Unions and a 1-1/2" bottom clean-out port. Another thing it has is a heavy-duty tamper-proof clamp and a clean-to-dirty pressure gauge so it tells when it is time to clean your pool. Using four cartridge elements means longer cleaning cycles and ease of maintenance. 


  • Four cartridge design simplifies element removal and extends the time between cleaning cycles
  • State-of-the-art internal design provides more efficient filtration
  • chemical resistant glass fiber reinforced polypropylene tank for exceptional strength and long life 


  • Heavy-duty manual air relief valve
  • 1-1/2" bottom clean-out port
  • 2-1/2" Valve Bulkhead Unions
  • Convertible to D.E. by simply changing the internals
  • Commercial grade stainless steel pressure gauge 
  • 2 1/2 inch internal plumbing minimizes restrictions and improves water flow

Incredible prices & free shipping for name brand products, not cheap knock offs! I placed my order on Sunday and received shipping confirmation on Monday! Filters arrived in the original Pentair Shipping carton the next day. Excellent company and service while saving big over the local pool store and cheap knockoff from large online retailer!

Outstanding support! Customer service has prompt responses and solutions to your pool needs. I am very happy with a replacement suction vacuum solution that was suggested. I bought it and it shipped to my home in 3 days. Great job and a pleasure doing business with this pool company.
