Designed to screw into a BSP female fitting such as an elbow or hose barb.
This drain does not come with a nut or washers for placement with pond liners, however they can be purchased separately - see bottom of page.
If connecting through a liner we recommend using a solid backing plate or similar to add to the stability of the connection.
