De-Winterizing RV & Spring-Time Tune Up

Regardless of what a ground-dwelling Marmota monax (aka ground hog) has to say about six more weeks of winter, likely you’re ready to get back outside, breath fresh air, and soak up some nature. In order to maximize you upcoming chill-time, a little preparation of your RV can go a long way as you wake your rig from a long winter’s nap.

De-winterizing an RV involves a few steps to ensure that all systems are functioning properly and ready for use. In a few easy steps, checks, and test, you’ll be ready to hit the open road and enjoy your RV even more than last season.

Before beginning the de-winterizing process, it is important to gather all necessary tools and supplies, including a water hose, water pressure gauge, antifreeze, water pump lubricant, a pipe wrench, and a pair of pliers. You will also need a freshwater source, and possibly a wastewater holding tank.

Exterior Inspection - Start with an exterior inspection of the vehicle for any damage or wear and tear. This includes checking for cracks or dents in the body, as well as any damaged or missing parts. If you notice any problems, it is a great idea to address them before hitting the road for that annual spring trip.

Water System & Pump Inspection - Start by opening the access panel on the exterior of the RV and inspecting the pump for any visible damage, cracks, or wear. If the pump appears to be in good condition, proceed with the water heater check.

Attach a freshwater supply hose to the inlet of the water tank. Now turn on the fresh water supply hose and the water pump. If the pump is functioning properly, it should begin to circulate water through the system. If the pump is not functioning correctly, it may need to be replaced.

Water Heater Testing - After testing the water pump, you will need to check the water heater. Start by attaching the fresh water supply to the city water inlet on your RV. Once the water is on, inspect for leaks in the restrooms, kitchens, and under cabinets. Now turn on the propane and light the pilot, if necessary.

Once ready, turn on the water heater and wait about 20 minutes and test by running hot water from a faucet. If the water does not heat up, the heater may need to be serviced or replaced. Next, switch from propane to electric and run the same test again and ensure one or both options operate as expected.

Fresh Water Flush - Once the water system has been inspected and tested, proceed with flushing out the water system and refilling it with fresh water. If the freshwater tank didn’t get drained when winterizing, start with draining the tank. Once the tank is empty, close the valve and refill with some fresh water and add a small amount of water pump lubricant to help prevent corrosion and extend the life of the pump.

If the RV was properly winterized, flush the freshwater system by attaching a hose to the fresh water supply and open the faucets. Typically, non-toxic antifreeze is colored making it easy to detect when the system is flushed completely.

Electrical System Inspection - In addition to checking and testing the water system, check and test the electrical system. This includes inspecting the batteries, checking the wiring for any visible damage or fraying, and testing the outlets and appliances to ensure they are functioning properly. If you notice any problems with the electrical system, it is important to address them before using the RV.

Pro-tip: If you RV long enough, you may run in to evidence of little mice that frequent open RV storage areas. They get cold in the winter and occasionally, look for warm shelter in an RV no one was using anyways. Who could blame them? If you see evidence, STOP. These critters are notorious for damaging wiring and waterlines. We recommend you start with a deep clean and then call Grant RV to inspect for any damage in all the hard-to-get spaces.

Deep Spring Cleaning - Finally, it’s time to spring-clean and maintain the RV. This includes wiping down surfaces, vacuuming and shampooing the carpets and upholstery, and washing the exterior of the vehicle. Also inspect and replace any worn or damaged parts, such as tires, hoses, and seals.
