That would be me. Rear slide. What’s the question?

Any other questions?

Have a question concerning a 2021 Greyhawk 29MV. Has anyone experienced issues with Black Tank Flush? When I hook up the water hose to the inlet port and turn on the water, water starts leaking in the bathroom. I am aware of a device that is supposed to function like an anti-siphon valve to prevent any black water from coming back through the flush plumbing. I could use assistance understanding if this is a systemic issue, a faulty device or a device installed incorrectly.

If you're getting a leak when you pressurize the system, I'd guess there's a loose connection in the flush line. If you look under the bathroom sink, then to the left you can see the vacuum breaker and the Pex lines connecting it, just below the countertop between the sink and the bathroom drawers.

Thank you "PC". A big help. The link and subsequent postings provided "clues" that I hadn't explored yet. I'll keep you posted.
