I am winterizing my 2630 Trek and I cannot get to the pressure pump to allow me to get anti freeze into my system. I am advised I need to fill a water hose with fluid to get it into the tank and then turn on pump. This seems like the hard way to do it as it will take >63 gals to fill a fifty foot 5/8 " garden hose. There is no way to pour the fluid in the pressure tank. The other issue is that they never installed a by pass for the hot water heater so I will need to somehow bug the hot and cold water lines so I don't have to fill thge tank with the antifreeze.. Any info would be appreciated. Ron in VT.
