Booking an RV parking space doesn’t prepare the water system for weeks off the road. Freshwater left standing can develop an unpleasant smell and require extra cleaning later. Draining it before the move helps owners avoid plumbing problems while their recreational vehicle sits unused.
Plan the Draining Before Moving the RV Into Storage
Preparing a camper for storage involves more than cleaning its interior and checking the tires. A full freshwater tank adds weight and leaves water sitting inside the vehicle throughout the rental period. Owners should arrange to drain it at home or another suitable location before heading to the facility. Scheduling this work ahead of time also provides an opportunity to inspect the plumbing for leaks. People considering RV storage units should check facility rules, since parking areas may prohibit water discharge and maintenance activities.
Where Should the Freshwater Be Drained?
Clean freshwater can generally be released at an appropriate location where local regulations permit. Driveways with suitable drainage or designated campground facilities may provide practical options. Discharging large amounts of water onto public walkways, neighboring property, or shared parking areas can create problems.
Water that has been sitting in the tank for months may also contain unwanted bacteria or sediment. Residents should avoid using questionable water for drinking or watering edible plants. Gray and black wastewater require separate handling at approved disposal facilities.
Locate the Drain Valve Before Running the Water Pump
Freshwater drain valves vary by RV manufacturer. Certain models have an accessible valve underneath the vehicle, while others place it inside a utility compartment. The owner’s manual identifies the correct location and operating procedure. After disconnecting the external water supply and switching off the pump, the owner can follow the manufacturer’s gravity-draining instructions. Opening a suitable faucet may help air enter the system. Running the pump continuously to empty the tank is not recommended because prolonged dry operation can damage its components.
Why Emptying the Tank Does Not Clear Every Water Line
Water remains in some plumbing sections after the freshwater reservoir empties. Low-point drains, outdoor showers, and connecting pipes may retain small amounts that need separate attention. Following the manufacturer’s instructions helps release trapped water without damaging fittings.
Leftover moisture can become particularly troublesome during cold weather. Freezing water expands and may crack pipes, valves, or pump components. Checking these areas before moving into self storage can prevent an expensive surprise when the RV returns to service.
Remember the Water Heater Has Its Own Drainage Requirements
The water heater does not necessarily empty when the freshwater tank drains. Traditional tank-style heaters may retain several gallons and require a separate procedure. Heating sources must be switched off, the water allowed to cool completely, and pressure safely relieved before opening the drain according to manufacturer instructions. Tankless models have different requirements. Some systems also need bypass valves adjusted during winterization. Incorrect handling can damage fittings or cause burns, making the equipment manual especially important before extended storage.
Does the RV Need Winterization After Draining?
Draining removes much of the freshwater, but it does not guarantee protection against freezing. Plumbing elbows, filters, and pump housings may still hold water. Owners expecting freezing temperatures should follow an approved winterization procedure using the methods specified for their RV.
Covered parking does not necessarily provide freeze protection. Those searching for storage units near me should consider seasonal temperatures, facility access, and how frequently they can inspect their vehicles. Automotive antifreeze should never enter an RV’s drinking-water system.
Keep the Freshwater System Ready for Its Next Use
Tank drainage and sanitation serve different purposes. Emptying removes standing water, while sanitizing helps address contamination that may develop inside the freshwater system. RV manufacturers provide instructions for approved cleaning products, concentrations, and flushing procedures. Before departure, owners should record which valves were closed or bypassed and leave the pump switched off as appropriate. After storage, they can inspect connections, refill the tank, and sanitize or flush the system as directed before using the water for cooking or drinking.
Check Storage Arrangements After Completing the Maintenance
A prepared RV is easier to park without needing additional work at the facility. Drivers should confirm parking dimensions, access hours, and restrictions on vehicle servicing. Designated RV parking differs from ordinary household storage units, particularly regarding available space and vehicle access.
For recreational vehicle owners, Storage Partner provides RV storage options at participating facilities. Customers can review available parking spaces and rental arrangements before moving their campers or motorhomes into storage. Completing freshwater tank maintenance beforehand helps keep the vehicle ready for its time off the road.
