Then close the gray valve and drop the hose. When water stops draining into the sewer you can repeat the process. ..................... Flushing always works best when the gray tank is close to full.Right on Brett! (+)1Lifting the discharge hose to create a loop seal and direct the grey tank effluent into the black tank is how I learned to do it 20 years ago. It hasn't failed me since.There are lots of ways to do things and it seems to me, every owner should have a personal philosophy on what they hope to accomplish with the time and money that they spend on modifications to their coach. Some favor "Keeping up with the Jonses", ignoring all logic, cost and reason. Some, thrive on incredible compounding of coach complexity, with each and every passing whim. Others just create obsessive nuggets of pure gold amongst the landscape of FT wonderment. I obsess on simplicity, increased reliability, lowered maintenance costs (through ever-smarter predictive maintenance), KISS and common sense. Using "Lift-The-Hose-Simplicity", the OEM Thetford sewer fitting (used by FT and most other high end coaches), a transparent joint elbow connection to the in-ground system, plus a high quality sewer hose, all properly joined, saves me time and money, is reliable, is maintenance free, is definitely KISS and operates purely on common sense, while giving excellent feedback on black tank condition. Another nugget of "common sense" wisdom - always close the Black Tank gate valve with grey water flowing INTO the Black tank (in order to be sweeping any "hung-up" debris IN, instead of OUT, as you close the Black valve.HTH - someone!Neal Quote Selected
