Hello. Is everyone having a good time?
I need to replace a section of drain under the kitchen sink because it has a sticking-up tributary on the back side for the dishwasher drain, and I'm taking out the dishwasher.
I really really don't want to disturb this house of cards under the sink. But I observe that there seems to be a few inches of expanded outside diameter at the input to the trap "U". Does this mean I can just loosen the top and bottom joints, tuck the unwanted pipe down into the "U" and tip it out, and reverse for the new pipe?
I mean, is the purpose or what appears to be a long mating area on the "U" intended to let people telescope a pipe in?
Thanks !!
