Steps
Park the sprayer on a flat surface and empty the tank completely. Catch the leftover liquid in a bucket so you can dispose of it properly.
Rinse the tank and plumbing with clean water to flush out chemical residue. Run the rinse water through the pump, boom and wand, then drain it all out.
Pour pink RV antifreeze into the tank. Check the antifreeze label for the amount and dilution your sprayer needs.
Turn the pump on and let the antifreeze circulate through the whole system. Open the bypass line so fluid moves through that path too.
Spray antifreeze through the boom and the spray wand. Keep going until you see clear pink fluid coming out of the nozzles.
Check the nozzles and fittings for any spots that still run clear. Run more antifreeze through until every outlet sprays pink.
Store the sprayer with the antifreeze left inside the pump, hoses and lines. Keep it in a dry spot out of freezing weather.
Tips and common mistakes
Draining the tank alone is not enough, because water stays trapped in the pump, hoses and fittings.
Wear gloves and eye protection when handling antifreeze and any leftover spray chemicals.
Dispose of drained liquid and rinse water at a proper collection point, not down a drain or on the lawn.
Questions
Can I use car antifreeze instead of pink RV antifreeze?
No. Use pink RV antifreeze, which is made for potable water systems and plumbing. Follow the instructions on the antifreeze label.
Do I need to flush the antifreeze out in spring?
Yes. Rinse the system with clean water before you mix and spray chemicals again, so the antifreeze does not end up on your lawn.
What happens if I skip winterizing?
Trapped water can freeze and expand, which may crack the pump, hoses, boom fittings or wand. That means repairs or replacement parts before next season.
