Okay, in doing further research...
I've found that for 1 1/2" pipe, I should be using a heavy-duty teflon
tape. But aside from that, that teflon tape isn't meant as a sealant,
except for tiny deficiencies in the threading. My leak appears to be
bigger than that. Don't even know if my threads are tapered in order
to provide the necessary waterproof seal (just learned about that
"Duh" factor!). If they aren't, though, should I then be using an O
ring? And if they are, what else could be the problem? Thanks.
