I did buy #721 and drove it 1200 miles back to Minnesota, other than it stalling and no restart it went fine. Question I have is how do I dump sewer on the drivers side, there are three buttons, one dump safety, another is dump open and another is dump close. what ever I do, nothing opens it. I can get the pass side to dump.

If you hear ‘air’ noises, valve is likely stuck. Apply manual pressure while pressing safety and open buttons.

Ensure grey water bypass valve is setup to allow tank to dump.

If no air noises, check that electric solenoid valve to open the dump valve is getting 12V when activated.

If getting 12V when activated, check that solenoid valve is freely operating.

You might have answered my question, I dont here and noises at all but it looks like I need to hit the safety button and open at same time?

To use the passenger side dump, the ignition key needs to be in the on position (or the engine running) regardless of whether you activate the dump from the bay or from the switch on the dash.

[Richard]

Yes. Safety and open at the same time. In later years, Newell added that feature to prevent accidental opening of the dump valve.

I think that safety switch was named the "Matt Russo" switch.
