I verified with Dometic Technical Resistance that it is an air gap but it also has a check valve in it. I’m going to check flow going into it this weekend and if all is good there I’ll order a replacement vacuum breaker as per Dometic.
Wayne- Who knows. I don’t see one on em the parts breakdown but stranger things have happened. what model from Dometic do you have?
