Years ago, I spent a few months working
for a plumber who spat out pearls of plumbing wisdom like a Pez dispenser.
Here's one of his best maxims: "Always dope everything."
Translation: Use dope (pipe thread
sealant) on plastic, rubber or metal, on washers, rings or gaskets, and
especially, on anything that has threads.
Even if the threads don't actually form
the seal (as on washing machine hoses), they screw together easier and come
apart easier later. And things that don't really require sealant (like
compression fittings) slip together smoothly and seal tighter with a little
favorite thread sealants contain Teflon. Be sure to choose a non-hardening product,
and READ THE LABEL. Some sealants can wreck plastic or rubber parts. My thread
sealant of choice is Rectorseal's T Plus 2. You can buy it through our
affiliation with Amazon.com: Rectorseal T Plus 2 Pipe Thread Sealant
