Ok, just redid my pump and filter connections, and everything went great, except that 2 of my 3 threaded fittings have a slow drip.
What's the secret here? I gave each 2-3 wraps of teflon tape, hand tightened, and then tightened some more. The ones on the filter appeared to be almost all the way in to the stop, but one is dripping and one isn't.
And maybe a better question is, there was no way for me to tell beforehand...how do the pros deal with this afterwards?
