- Your Vent Cowl has a female socket, so it requires a male pipe or flanged fitting for installation.
- Use a holesaw to cut an appropriate sized hole in your rainwater tank to fit your pipe or flanged fitting.
- If installing your Vent Cowl with a pipe, insert the pipe into the hole you’ve cut and glue it in place with an appropriate sealant.
- If installing your Vent Cowl with a flanged fitting, place silicone on the underside of the flange, press it down onto the tank over your cut hole, and screw the flange to the tank surface.
- Install your Vent Cowl by placing it over the male pipe or flanged fitting and glue it in place using solvent weld glue.
