Make sure fresh water tank is empty and black and grey tanks have been dumped with no chemicals in the tanks.
Open all the faucets and inside shower to let water clear from the lines. Don’t forget the outside shower. Close all faucets after they have run dry.
Open the low point drains and let drain until water stops running out.
Take pressure off the hot water heater with the relief valve and remove the anode rod.
Run the water pump for about 30 seconds.
Open the bottom right panel on the entertainment center to get to the water pump and water filter. Carefully remove the water filter housing and dump the water. I hold the fitting at the top of the filter while removing and replacing so as to not twist all the plumbing fittings. Be careful not to damage or lose the O-ring inside the filter housing. Remove the cartridge for the winter. If you are going to use the filter next season, let it air dry and then put in a freezer zip-lock bag and freeze for the winter. If you are going to use a new filter cartridge; replace in the spring. Put the filter housing (with O-ring) back in place.
I use the air compressor run between 35 to 40 psi with the special adapter I showed you in a previous picture. I first put it in the fresh water fill valve to make sure all water is blown out of the fresh tank. Close the fresh tank dump valve. You are done with it until spring.
Hook up the air line to the black tank flush connection on the side of your trailer. Blow out the line with your dump valve open to get all water out. Once you are down to a drip you can remove the air line and close your black tank dump valve.
Hook up the air line to the city water connection on the side of your trailer. Then go around and open one faucet at a time to let any water run out and close that faucet. Do this for both hot and cold on the outside shower, inside shower, kitchen sink, and bathroom sink and then flush the toilet. Once I have done this I turn on the water pump and quickly repeat these steps. Turn off the water pump and remove the air line from the outside fitting. You are finished with the air compressor at this point.
Turn the valve on the water pump to bypass its use and to enable the antifreeze pickup port to be used. Double check your water filter canister. If you have accumulated more water remove, dump and replace again.
Access the hot water heater and close the cold water “in” valve, hot water “out” valve and open the valve in between the water lines.
I put my anode rod back in loosely just so it doesn’t get lost or allow bugs to crawl inside. Replace the caps on the low point drains and make sure your dump valves are closed. All faucets need to be closed as well.
It will take about 3 gallons of RV antifreeze to do the entire system. I believe I sent you a picture of a suction tube with hose end fitting that I assembled. I use the clear tubing so that I can monitor the flow of the antifreeze going into the trailer.
Hook up the hose end fitting to the antifreeze port on the side of the trailer. This is where you really need two people. Patty will be inside and turn on the water pump. I stay with the antifreeze jugs to switch them out as needed.
It takes a little time for the antifreeze to be “picked up” by the pump but you will see it flow into the trailer. The water filter canister will fill up first. I start with the outside shower and open up the cold side first and leave it open until pink stuff runs freely out the showerhead. Close and repeat process on the hot water side. You need to do this complete process with the inside shower, both sinks and finally the toilet. You will probably see some water still come through so make sure you are running strong pink streams with each side of each faucet. Let your inside toilet flush valve run until you get plenty of pink stuff there as well. Turn off your water pump.
Pour antifreeze down each drain (both sinks and shower) and also on top of the valve in the toilet to block odor and keep the seal moist.
Close up the cabinet doors where your water pump/water filter is located as well as the hot water heater. Check for any leaks in these areas before you seal them up. Wipe down the sinks, shower, etc. because the pink stuff may stain. Keep your freezer door and fridge door cracked so they don’t get musty smelling.
You’re done! I remove my battery for the winter and keep it on a maintenance charger which cycles automatically. Fairly inexpensive at Wal-Mart.
I mentioned dryer sheets, mothballs, Irish Spring and Damp Rid in my previous email. I also keep my roof vents cracked a little bit for some air flow.
