These fittings require a 1-3/8" (35 mm) hole to be drilled in your flood tray. After inserting the 1/2" Bulkhead Fitting into the tray, use 1/2" tubing to connect to your water pump. Install the 3/4" Bulkhead Fitting in the tray and attach the Bulkhead Extensions to maintain the desired water level in the flood tray while the water pump is running. Attach the Bulkhead Screens to the top of both fittings to prevent debris from entering the reservoir and to prevent water from shooting out and splashing when the pump is on.
