Crank up your tm.
Suck all the water out of your water box
Fill it up with low -20f temp windshield washer fluid. 5 gallons average
Turn your water pump on
Hook up your solution hose
Open it up to push all the water out of the hose until you see the windshield washer fluid
Put some of the windshield washer fluid in your rinse jug
Prime the chemical pump
Hook up your carpet wand, hydroforce, tile tool, uph tool. Run WW fluid through those as well to protect the trigger valves
