I have 2" flex pipe coming out of the ground from the pool drain. Flex pipe is that hard black plastic stuff that is a bit flexible, but when mistreated, can split. So I found the leak and patched it with Gorilla Tape and hose clamps. But, tape being what it is, will leak again. Do you know of anything to patch it? Any kind of marine sealant like 3M 4200 or 5200? Hoping that since we're in the 21st century, there is a product that will take care of it. All the pressure comes from the outside of the hose since it is an intake line. Thanks in advance for your opinions.
