Attaching the Wall Plate

If you have a liner
Mount the outer flange plate behind the liner but inside the pond structural wall, with the
top of the plate at around water level. Bore through pond wall structure using a 90mm core
drill or similar in line with the hole in the outer flange. Cut liner out inside the 90mm
aperture in the centre of the outer flange plate.
The through wall pipe will then fit through this hole, with the long end going through the
pond wall and the airlock pipe on the "pond side". Put a liberal amount of sealant on the
welded flange, liner side, on the through wall pipe and slide the pipe in through the hole in
the liner, outer flange and pond wall. Align the screw holes and use the 6 screws to join
together the outer flange and through wall pipe flange, clamping the liner in place.
