Gray Water Drain Valve

[M and R]

Gray water valve will not open with the switch. I can hear the motor run, but no water. The instructions in the manual are of little help. Does anyone have experience opening the valve manually? Thanks in advance!!

I went on line to find instructions for disconnecting the knife valve from the rod coming out of the motor. A rack and pinion setupI think. Send me a PM with your e-mail if you can't find something on-line, and I'll go out to Titus and find my paper copy and scan it and send it to you. An open end wrench and an allen wrench if I remember correctly.

Found a post by Boxter1971 from 2015 He had a pdf link to the Barker schematic. I will try again. Thanks for the help.

The hose could have a kink in it, let it all the way out and check for a flat spot.

Try emptying the black tank to be sure that the problem is really in the gray tank valve and not elsewhere.

Black dumps ok so hose is ok too.
