Question. I installed a anti back flow check valve at the black tank connection. While it has water flowing through it, everything is fine. When I cut off the valve at this location, water blows out around the back side of the plastic fitting. Not leaking at the hose connection. It's back behind this connection next to the aluminum panel. Would this be normal?
