If your sink drain clogs

First time out since winterizing, the kitchen sink was clogged when we purged the air from the supply lines. This is Venture's version of a P-trap, used for drawer clearance issues. They use some type of black sealant between the ABS and PVC joint, but I reassembled with Teflon tape.



The gunk in the trap must feed on RV anti-freeze and seals the flaps together.



This is what it should look like.
