What is normal is gray and black tanks have their own drain pipes and each a drain valve. Those 2 or 3 come together into 1 dump pipe with a cap at the end. Sounds like yours are 2 complete separate pipes. So, dump black, when empty disconnect the sewer hose. Than repeat with the gray. That way gray water may move debris thru hose that was left over from the black tank. I still wash the hose out again before putting it away. Also do your self a big favor. Buy a sewer pipe cap that has a fitting for a garden hose. This is so that incase you remove that sewer cap and than find out you have a valve open and have stuff flying all over. So, with that garden hose cap. Hold your sewer hose under it and open slowly. You will prevent getting covered with that stuff flying out of the sewer. Yeah it happened to me. Only once.
