- Glue the first 1" length PVC pipe into one end of the 90 degree elbow.
- Glue the 45 degree elbow to the other end of the first 1" PVC pipe.
- Glue the second 1" piece of PVC pipe into the other end of the 45 degree elbow. The length of the second piece of PVC pipe can be shorter, if you prefer.
- The PVC 90 degree elbow will slip-fit over the Hagen output nozzle without modification. Allow the assembly to completely dry before placing on one of the powerhead output nozzles.
Note: The 1/2" PVC pipe and fittings are normally tight enough that they can be assembled and used without gluing. Doing so will allow you to adjust the water flow to suit your needs before permanently gluing the parts.
