it should go underneath your base and up outside your blocks not inside just behind the liner as this will cause hollow spots around the pipe behind your liner and at 5ft deep the water pressure is enough to strech and tear your liner also it would create a lot more creases to fold it around the pipe espescially where it meets the floor hope this helps
