We have a 2019 Coachman Leprechaun 280ss. The black tank flush line is not working this season. I have read many posts about the check valve and vacuum breaker valve. I do not find a vacuum breaker valve under the sink. I have pressurized multiple times with water. I pressurized with air compressor. Filled black tank with water and Dawn soap. Let it sit for 24 hours. Still clogged.
1. Does anyone know where in a Leprechaun they may have install the vacuum breaker valve?
2. Would the flush port be behind passenger rear wheel about half way up black tank? There are no letters on this fitting.
Thanks for information.
