Hello. Im a proud new owner of a 2011 260 sundeck. When I tried to empty the waste tank which was showing “full, do not flush”, at the marina, it only pumped out about 1/3rd of the waste. The indicator now shows 1/2. The suction of the pump at the marina appears to stop sucking because there’s too much air being sucked in. Does that mean I have a leak of air somewhere? I also noticed some liquid coming out of the waste vent when pumping out the waste. I’m completely new at this, any advice would be appreciated.
