Aquatic collection has 2" in stock. You can use slip and glue a cap or plug, or threaded with a cap or plug and teflon tape or liquid teflon(I prefer this for pipes larger than 1", and pretty much all threaded pipes actually, but especially larger diameter pipes).OK -- so I need an ABS 2" bulkhead threaded from BRS and then I need to go to HD and get a 2" threaded plug and teflon tape? Correct?
