my cleanout is about 1 ft higher than the trailer dump valve. I've used the floject for years now. The main cleanout is further away than I wanted, so we dug down on the cleanout pipe, added a sanitary T, and ran pipe to near the side of the driveway to make a dump station. Just make sure you have some downhill slope in any added run to the cleanout.
1) I made a 12V circuit from the battery to a marine plug near the valve so I can easily plug in the flojet.
2) I bought a 3/4" diameter water hose dedicated to the flojet
I back the trailer into the driveway and dump away. Works perfect
