Monitor your black tank flush –
Simple enough, there are a number of clear RV Sewer Adapters available from straight to 90-degree angles which allow you to watch the liquid flowing from your RV. When flushing you’ll be surprised how long it might take to make certain you have clear water flowing from your black tank. Also, monitor your grey tanks since the RV pipes often allow some backup from the black flush. With the adapter you’ll be able to monitor all your flush activities ensuring you have empty/clean tanks and sewer lines.
