Happy 2018 everybody. I am brand new to the community having just took possession of my 1st Sea Ray yesterday. The 1st few questions I have I just can't find answers on: My heat exchanger hose hookups are on the starboard side stern, but I don't know if there's a check valve, engines on, or engines off? She has 7.4s and a closed cooling system if that helps. 2d, how do I flush the HVAC? Also, I assume the sink in the bathroom dumps into the waste tank? Thanks to anyone who can help and sorry for the ignorance, I just upgraded from a 22 WA with a single 225 OB...
