It is the SSC Fun Finder T-189 Fr Br. I had the hose hooked up to it to flush out the faucets and get rid of the anti-freeze….but I forgot how to get the fresh water tank to fill up…do I need to use the pump?? Does anyone know?? Maybe it is very similar to other campers. I have a water heater and a bypass valve. Just couldn’t get the water to run into the fresh tank. Any ideas???
