RV winterization
Water left in a line, fixture or filter housing can freeze and damage it. Ask Kirk about preparing the plumbing on your motorhome, travel trailer or fifth wheel before temperatures drop.
Getting your RV ready for freezing temperatures
Tanks, lines and the water heater
Your RV’s layout determines what needs to drain and how the plumbing and water heater are protected. Tell Kirk whether your water heater is tank-style or tankless if you know, and whether the RV has a winterizing connection or bypass.
Fixtures that are easy to miss
Mention outdoor showers, water filters, spray ports, washing machines, ice makers and any plumbing added after purchase. Those components can hold water even when the freshwater tank is empty.
Timing before freezing weather
Tell Kirk when you’ll last use the water system and if any fixture already leaks. For a mobile appointment, share the location and whether water or power is available. If you plan to use the RV again during winter, explain how you’ll use the plumbing so you can discuss what needs to be done each time.
Common questions
Is draining the fresh-water tank enough?
Water can stay in supply lines, drain traps, filters and fixtures after the tank is empty. A water heater or outdoor shower also needs to be accounted for. The way to protect those components depends on how your RV is plumbed, so tell Kirk about accessories and any modifications that changed the original layout.
Do tankless and tank-style water heaters winterize the same way?
They can have different drain points and procedures. Some tank-style systems have a bypass, while tankless models can have their own requirements for protecting internal components. Share a photo of the heater’s model label and any recent changes to the plumbing so Kirk can check what applies to your unit.
Does my RV need antifreeze in the lines?
Some manufacturers specify draining and blowing out the lines, while others describe an RV antifreeze procedure or steps for specific components. The right method depends on the manual and the equipment in your RV, including filters and appliances. Tell Kirk how it was done last time and whether you added any fixtures since then.
What if I use the RV again after winterization?
Tell Kirk whether you plan to use the water system or camp with it left winterized. Once water goes back into the plumbing, it can remain in lines and fixtures even after the tank is drained. Plan when the system needs to be protected again, especially if the RV will be parked outside during another freeze.
