Hmmm, Tom & Ken...Thanks I was worried about residual un-pinked water in both the city stub to pump and that black tank flush line. I used a shrader to hose fitting and hit them with about 40psi to be sure these were clear of water. I guess I better go recheck that antisiphon location where I saw liqiud previously...maybe its gone now? Didn't think all the line would be necessary to feed a black tank flush nozzle...geez.
