You can actually seal a pipe EPDM junction by cutting the hole 1"
smaller than the pipe, so it makes a lip on the pond side. Some use a
clamp on the lip, others don't bother, so long as the lip is on the
water pressure side of the seal.

I'm so glad to see pictures on the web. Greg Bickal use to have a great
site with all these DIY cheap pond fixes, and then he put them on a CD for
$10. Worth the money.... but when you're looking cheap, and need it now,
nice to see it on the web again. Different author same info. :-) ~ jan
