Arrghh ever since the days of the pirates I’m sure skippers have been cursing this necessary piece of yachting hardware. Yes are techs are savvy about setting them up so they do their intended duty(no pun intended). Of course given the choice our crew would rather be bolting down deck hardware or tuning the mast for performance. Nonetheless we can and do help out with holding tanks, Y valves, and the toilet. If you are considering a fresh water set up, composting model or just want your current system to stink a little less, ask us we know the drill.
