Flow Control Extension Kit
4"
The lower ring fits over the outside of the access opening on the top of the flow control body, allowing the installer to maintain a clean sleeve (using pipe) up to finished floor level. This part is used with a 4” flow control.
This item is not available for the 2" flow controls. 2" flow controls cannot be buried below ground, against plumbing codes in many areas.
