Can't find drain plug for fresh water tank ..1990 HR TT ALSO DOES IT HAVE BYPASS VALVES SOMEWHERE FOR HOT WATER HEATER? Appreciate feed back. Just bought this. Great shape.
As far as the water heater goes find the back side of it and you will see the lines going into it, if it has a bypass you will see a couple of valves. If it does not you can get a kit for around $25.00, easy to install. Fresh water tank probably has a valve on one end to empty.
