    • Recessed sock plate lowers sock rim below water level to prevent bypass. Sump holds one 7" sock.
    • No warp drop-in flush lid above socks reduces noise and splashing.
    • Slotted relief above sock chamber allows overspill in the event of a clog without excessive noise and splashing.
    • Original design removable bubble trap allows sump to function with or without bubble trap for additional return chamber space. A standard adjustable wall plate is included for operation without the bubble trap. The bubble trap assembly contains a removable slide tray for media holding and is locked into your desired water level height with black nylon bolts and actual black nylon nuts. No more broken threads in tapped walls. No more hard-to-reach slim bubble trap areas near impossible to clean. This is a game changer.
