2015 Keystone Cougar 31SQB Blackwater Flush

[Imthek9]

Hey guys - on a trip right now and having some issues. I need to flush my black water tank which I have a connection for in my panel next to the city/tank fill spicket. I took the White House (which has a filter and pressure regulator attached at water source) disconnected from city line and put it into the tank flush connection. I then turned the water on - I had the termination valve open for both grey and lack tanks to the sewer. The water turns on but seems like it stops some where. I don't here it running anywhere, and when I disconnect the hose there is pressure that pushes water back on me when hose is disconnected. Should I remove pressure regulator? Do I need to close grey tank? How do I do this the owners manual has proved useless.

Thank you,

Stephenhttp://images.tapatalk-cdn.com/15/07/02/2a183963e3af52d79f497969bca3a8d3.jpg

I have the same trailer Brother. Remove the pressure regulator, Close the Gray tank and leave the Black tank open. Also, PM sent.
