2.1. Thoroughly Drain and Flush the Black and Gray Water Tanks
Why is it critical to drain black and gray water tanks before winter? Wastewater left in tanks can harbor bacteria, freeze, and cause damage. Start with the black tank, then the gray tank. Use a specialized black tank cleaner or wand for a thorough flush.
According to the RV Industry Association, neglecting this step is a leading cause of RV plumbing damage during winter.
2.2. Completely Drain and Flush the Water Heater
How do you properly drain and flush an RV water heater? Turn off the water heater, let it cool, and relieve pressure. Connect city water with the water turned off. Use a socket wrench to remove the drain plug or anode rod and open the pressure relief valve. Flush sediment for 2-3 minutes. Leave the anode rod out if old, and remember to replace it in spring.
2.3. Correctly Bypass the Water Heater
Why is bypassing the water heater necessary when winterizing? It prevents antifreeze from entering the water heater tank. Locate the water heater, find the access panel inside, and adjust the valves to bypass it properly.
2.4. Empty the Fresh Water Tank and Low Point Drains
What’s the procedure for draining the fresh water tank and low point drains? Turn off water pressure before removing the plug and draining the fresh water tank. Open faucets to aid flow. Close faucets and plug low-point drains when finished.
2.5. Access and Prepare the Water Pump
How do you prepare the water pump for winterization? Attach the siphoning kit or locate the siphoning hose if equipped. Place it in a gallon of antifreeze and open the valve. Turn on the water pump to start antifreeze flow.
2.6. Treat External Faucets and Valves Methodically
Why is it important to address external faucets and valves during winterization? These areas are prone to freezing. Starting with the lowest valve, open low-point drain valves or loosen plugs until antifreeze (pink fluid) appears. Then close them. Treat outside showers and exterior faucets similarly.
2.7. Address Internal Faucets, Showers, and Toilets Systematically
How do you ensure antifreeze reaches all internal plumbing fixtures? Repeat the process from step six inside, running faucets, showers, and toilets until antifreeze is visible. Address both hot and cold sides of each fixture.
2.8. Protect P-Traps with Antifreeze
Why should you pour antifreeze down P-traps? It prevents exterior termination pipes from freezing. Pour additional antifreeze down each sink, shower, and toilet drain. Double-check that the water heater’s heating element is off and all faucets are closed.

4. The Science Behind RV Winterization
What scientific principles make RV winterization effective? Understanding the science helps appreciate the importance of each step.
4.1. The Physics of Freezing
How does water freezing impact RV plumbing? Water expands by approximately 9% when it freezes, creating immense pressure within pipes and tanks. This expansion can cause pipes to burst, tanks to crack, and fittings to fail.
4.2. Antifreeze Properties
What makes RV antifreeze effective in preventing freezing? RV antifreeze, typically made of propylene glycol, lowers the freezing point of water. This prevents ice formation at typical winter temperatures. Propylene glycol is non-toxic, unlike ethylene glycol (used in automotive antifreeze), making it safe for potable water systems after thorough flushing.
4.3. Thermal Expansion and Contraction
How does temperature fluctuation affect RV components? Materials in RVs expand when heated and contract when cooled. These changes can stress seals, joints, and other connections, leading to leaks and failures. Proper winterization minimizes water presence, reducing the risk of damage from expansion and contraction.
4.4. The Role of Insulation
How does insulation contribute to RV winter protection? Insulation slows heat transfer, helping to maintain a more stable temperature inside the RV. This reduces the risk of freezing in plumbing and other sensitive areas.
Understanding these scientific principles underscores the importance of thorough and correct RV winterization.
