Core Holes are used for inlet and out let and transport pipes as well as submersible pump outlets and electrical conduits.
If you require core holes you will need to fill out our Tanket Core Hole Drilling form informing us of where you would like the tanks core holes. Click here to download Core Hole Drilling Form.
Please note for multiple tank purchases one core drilling form per tank.
If you are connecting 2 tanks or more tanks you will ideally need transfer pipe/s. In this case you can have High flow and Low flow core holes. We have different core hole sizes and engineered design Hole Seals to suit.
