I purchased a model 8329 2002 Gulfstream in June of this year, so this is the first winterization effort for me. My question deals with the design of the drain valve. Regardless of the direction I turn the valve, I get no flow from any of the three valves. (2 behind the hot water heater on the passenger side and 1 in the service compartment on the driver's side) I suspect that the valves may actually be line plugs, but I have no literature, and I didn't want to force the valve and cause damage.
Thanks in advance for your help.
