I've always been confused as to which way the cone-shaped plastic
washer should face when installing kitchen sink PVC tubing - there are
2 configurations - one is from nut + inside washer + thread and the
other is from nut + sliding washer on tube body + thread. Which way
should the tapered or pointed end face in either case? The first one
has a flange and the second one simply slides on the tube body. Do
they both face the same direction, and if so, which way, and if not,
which tapered end faces which way relative to the inside of the nut?
Thanks for a quick reply - the sink is leaking like crazy.
The pointed end slides into the compression counterpart, squeezing
the washer as the nut it tightened. If you look closely, you'll
see that the inside of the fitting itself has a taper to it,
intended to squeeze the washer.
Thanks, I can see this for the sliding washer. But what about the same
washer being compressed against the flange underneath the sink basket.
It looks good to see the flat portion seat against the underside of
the flange but shouldn't it be the other way around? Is the
compression force being applied on the flat side in both cases, and
not on the tapered side?
