If You Have Only A Solid Wall/ Fibreglassed; Attaching The Gate Valve - DracoDrum DracoDrain User Manual

If you have only a solid wall/ fibreglassed

The outer flange plate is not needed in this case. Approximately 2 to 4 inches below normal
water level, bore a 90mm hole through the pond wall and/or fibreglass. Apply a liberal
amount of sealant to the inside face of the flange that is welded to the pipe. Slide this pipe
through the bored hole until the flange fits snuggly against the pond wall. If necessary, drill
into the pond wall for each of the 6 clamp screws and fit accordingly.

Attaching the Gate Valve

Slide the gate valve over the end of the through wall pipe and either glue or silica it into place.
Make sure you keep the gate valve closed until you are ready to open the system.
