More about the Waterway 550-0231 Medium Filter Lid & Lock-Ring Assembly (550-0621):
Waterway filters are among of the very best options for handling the larger debris and exposure associated with above ground and below ground outdoor pools.

Sand filters are generally the only option for outdoor pools, due to their ability to process silt and foreign objects while serving a large volume body of water.

Installation is simple. Mounting hardware is built into the molded plastic design of the lid itself. The lock-ring assembly snaps on, as the final pressure-balancing aspect of the sand filter.

Got any questions, concerns, or maybe you're just curious to learn more about installing your new filter lid? Let us know! Our pool pros are on standby, and they love to share their hard-earned knowledge with our customers.

Is your filter lid cracked? Is your lock-ring no longer sealing properly? We've got you covered! But don't wait long. This cool Waterway 550-0231 Medium Filter Lid & Lock-Ring Assembly offer only stands at 15% off MSRP as long as our current stock holds out from demand.

P.S. -- there's another great offer waiting for you, partner! Pick up Waterway parts or supplies this month, and you'll get an invite to our secret deals slate. These great offers can't be published any other way, due to how much below MSRP they go! So why delay? Jump on in, the water's always nice and cool at Wild West Pool Supplies!

NOTE: Due to the manufacture changing the design of the tank, there is a fitment issue when trying to mate the old bottom (550-0201, replaced by 550-0601 - both have been discontinued) to the new tops 550-0611 (75 & 100 sqft), 550-0621 (125 & 150 sqft), 550-0631 (175 & 200 sqft). It is recommended that you replace the bottom when replacing the top.
