Be careful with black hose/tubing/pipe. Cut a small length of it and
put it into a microwave oven along with a cup of water for varying
lengths of time, checking each time. If it comes out cool when the
water is about to boil, it's probably OK. It seems some ABS and black
drip tubing has some semi-conductive ingredient(s) like carbon? I've
also seen white PVC fittings that failed this test.
