Or replace it all if need be. From what I've seen, HVAC guys all use
glued up PVC pipe, with nice plumb horizontal and vertical
runs. This make the water slow to drain and encourages funk
growth. And makes it impossible to disassemble for cleaning. Makes
for *great* job security, no doubt.
Buy PVC, including a pre-formed trap. Angle it for good
drainage. Just press-fit it together. And make some match-marks so
you can dis- and re-assemble it to clean. I like to install a tee
fitting with a short vertical run and cap, just upstream of the
trap; you can pour bleach in at the end of the cooling season to
help keep things clean.
Also take apart the "sump pump" if equipped and clean it out.
