Keystone /Black Tank Flush// update

they finely got to my trailer. I was hooking up to water hose to the right connection for Flushing out the Black tank after empting it. there was no leak found, no water in the Trailer or under belly. what they found was when the water hose is hooked up and full water pressure is turned on, as the water goes in, the line is about 3" in and then a 90 Deg. up into a reducer/ relief valve. this cuts the water pressure to a Trickle. from there the water line goes makes 90 Deg. for 1", then another 90 Deg. down. this line now goes down to the Hot & Cold junction under the Shower stall, then down again and under the flooring and to the side of the Black Tank.
the water coming out of this line was so reduced in pressure it not Flush the tank, it just dribbled into the tank, not even fast enough to see coming out the clear elbow on the sewer hose. have to take it in next week to see if they can get pressure enough to spray into the tank.
thanks for putting up with my frustrations, sorry if I offended anyone,

That sounds ridiculous to me. How in the H did they expect that to be able to flush and rinse anything??

Well, they found the main problem, that Black Glue the use was blocking the hose at the tank spray head. I will have to try it to make sure it is working OK.
