In the manual I got from Tiara they want you to drain the tank instead of pumping tank empty because pumping leaves more water in tank as opposed to draining.this is important in that you would have less water to dilute the concentration of antifreeze you put in.only problem with that is when you can't access drain and have to just go with pumping out water .tiara said to put 5 gals of the pink stuff in but I didn't have the temperature protection I wanted so I had to put more in to achieve that.it would also be nice to know where pickup is also so you would know if maybe you should winterize before pitching boat up for winter.i suspect pickup is forward and this led to residual water in tank necessitating extra detox to get concentration to proper level after pumping through system.bill

The best way to winterize the potable water system is to open the drain on the water heater and let that go into the bilge. Then isolate the fill line to the water heater so new water does not fill the empty heater. Then pump antifreeze through the potable water lines one at a time until pink antifreeze comes out of each line. Connect a funnel to the outflow end of the water filter and use the potable anti freeze container as the source of anti freeze instead of the fresh water tank. Remember to winterize the line to the head as well. Dump a gallon of antifreeze into the head after the holding tank is empty and flush it through. Open the macerater valve and run that until pink comes out the discharge . Remember to do the same with the ice maker, wet bar, shower in the head and transom shower. Do not add anti freeze to the fresh water tank as it will take forever to get rid do the taste when you turn the system back on. The water tank and heater will not crack because there is room for residual water to expand in these nearly empty tanks.
