1. Open relief valve on hot water heater and drain the hot water heater.
2. Find low point valve and open to drain
3. Find the water tank and close the valve; insert tube into antifreeze
4. Turn water pump on and circulate antifreeze in all water lines
Is this right? Where would I find the water tank with the bypass line???
There are two bypasses you need to handle, using the pink antifreeze method (versus the compressed air method, in which you just blow the water out of all the lines after draining the system).
One bypass is the hot water heater/tank. There will be valves to accomplish that, usually mounted on the backside of the hot water tank. Many rigs have accessibility to those valves under the kitchen sink.
The other bypass is the fresh water tank itself, unless you are going to fill that tank with gallons and gallons of antifreeze and then pump it through the system... which is what many manuals recommend, but is the most inefficient and expensive method. So, you "bypass" the fresh water tank by adding a kit to your water pump that allows the antifreeze to be sucked directly from the jug, without drawing anything from the tank.
Some rigs come with that bypass option, but many you'll have to install it. And your water pump may not be simple to locate, often mounted behind cabinets and accessible through a panel that has to be removed.
I'm sticking with the compressed air method this year, once I find my low point drains (it's my first winterization with this trailer).
