NOTE: When winterizing, you will definitely want to bypass the Alde system.<\/em><\/p>\n Step 1: Drain all the tanks. NOTE: the freshwater tank drain valve is located underneath the entry door steps.<\/p>\n Step 2: Open the hot and cold water drain valves located underneath the seating area by the Alde System \u2013 open one at a time to create a pressure system.<\/p>\n Step 3: Lift the Alde Relief Valve (the yellow valve that flips up and down and is connected to the blue water pipe) and allow the Alde hot water tank to drain. (See image below)<\/p>\n Step 4: Once the unit is completely drained, switch all the valves from Camping Season Mode to Winterization Mode. (See image below.)<\/p>\n Step 5: Once you have all the valves in Winterization Mode\/ Bypass Mode, add RV Grade antifreeze. Pour 4 to 5 gallons of antifreeze into the freshwater tank, then turn on the water pump to pump it through the system. If you want to save antifreeze, connect a line directly from the pex side of the water pump and pump antifreeze directly into the lines instead of dumping antifreeze into the freshwater tank.<\/p>\n Step 6: Open every faucet one by one (including the shower faucets) until antifreeze comes out to ensure they are protected from freezing.<\/p>\n Step 7: Pump the toilet to make sure the toilet is protected.<\/p>\n Step 8: Pour antifreeze down the traps\/drains.\u00a0 Pour RV antifreeze into your kitchen sink trap (.25 gallon or 1 quart), bathroom sink (.25 gallons or 1 quart) and into your shower drain (.50 gallons or 2 quarts). Note: The traps are very susceptible to freezing so this step is very important.<\/p>\n Step 1: Drain the fresh water tank by opening the water tank drain and leaving open.<\/p>\n Step 2: Turn the water pump ON and open all hot and cold-water faucets. When the flow of the water stops, turn the pump OFF. Open the low point drains on the hot and cold-water pipes.<\/p>\n Step 3: Drain the Alde system by opening the Alde pressure relief valve. (This is the yellow valve that flips up and down and is connected to the blue water pipe.) (See image below) Step 4: Depress the toilet flush pedal or hand-operated lever. Turn OFF all faucets, close the water line drain valves, fresh water tank drain valve, water heater drain and pressure relief valve.<\/p>\n Step 5: Drain the shower head and hose by disconnecting the hose at the faucet from the inside and outside shower.<\/p>\n Step 6: Drain the waste water system by following the normal procedure for draining the holding tanks.<\/p>\n Step 7: Be sure ALL water from ALL the plumbing has been drained.<\/p>\n Step 8: Once the unit is completely drained you will want to switch all the valves from Camping Season Mode to Winterization Mode.<\/p>\n Step 9: Turn your Alde bypass valve to the Bypass mode. (This is in the back-driver\u2019s side of the unit where the 3 drain valves are located. This step is very important).<\/p>\n Step 10: Pour 4 to 5 gallons of RV antifreeze into the freshwater tank.<\/p>\n Step 11: Turn your water pump on and open ALL faucets until antifreeze comes out.<\/p>\n Step 12: Pour RV Antifreeze into your kitchen sink trap (.25 gallons), bathroom sink (.25 gallons) and into your shower drain (.50 gallons). Note: The traps are very susceptible to freezing so this step is very important.<\/p>\n As always, check your owner\u2019s manual for specific instructions for your RV.<\/p>\n","protected":false},"excerpt":{"rendered":"![\"\"](\"http:\/\/nucamprv.com\/wp-content\/uploads\/2019\/09\/Winterizing.png\")
