There are several ways. One use two shower drains, one inside and one
outside and bolt them together, using stainless bolts. A little silicone
caulk applied to the face of the shower drains before bolting is advisable.
Another method is the Bickel Boot. For this, just use a piece of pipe,
about twice the diameter of the hole, push the pipe though, causing the
liner to cone around the pipe, put a stainless pipe clamp on the liner to
hold it to the pipe. This method would require adapters from current pipe
size to larger and back.

I have an above ground pond with a rubber liner. The line the recirculates
the water from the lower pond to the upper pond is a pvc pipe (plumbing
variety. It pierces the rubber lining below the water line of the upper
pond.

This penetration leaks. Are there any recommendation on how to fix this
leak.
