Hi, we had our vacuum flush toilets worked on just recently and now I can't turn on the water anywhere on the boat. The pumps are on but is there a switch I don't know about that the maintenance guy could of flipped other than the control panel? Its a carver 370 1993. The toilets work great now but can't get any water to fill the toilets or come out of any of the faucets? Hopefully its me being stupid.
