We are winterizing fifth wheel for the first time by ourselves. According to what we have researched, we blew out all the water with air compressor, emptied water heater, turned on the bypass valve to the water heater. We put six gallons of RV antifreeze in the fresh water tank and turned on the water pump. There is still no antifreeze coming out of the faucets. Any advice?
First make sure you closed the low point drains. If not you pumped all the antifreeze out on the ground. Next check the water heater. Just to make sure the antifreeze didn't go in there. You said you turned the bypass valve but it is possible there is more than one valve or if it is a single valve system that the check valve is bad. Next would be to check for other valves. I have one that allows a circular flow back to the tank. The pump will run all day just pumping water from the tank through the lines and back to the tank. And as many have said, find your pump and install a winterizing kit. It will make the process easier and you will use a lot less antifreeze.
