This is a Flow Control Orifice with 1/4" hole as required by some local building code to restrict the flow of rain collection or other water retention systems (such as a cistern) that require hookup to municipal water systems. Top is removable for cleaning if needed. Flow in the picture is from the cistern on the left to the right. Inlet and outlet are 4" IPS pipe size (Sch 40, Class 200, etc. WILL NOT Fit SDR35 pipe.) Top is a standard 4" MPT plug.
