What happens here

After the final flush, the presenter turns off the sprayer and discharges all remaining pressure by squeezing the spray gun's trigger until no more fluid is expelled. He emphasizes that this is a critical step to prolong the pump's lifespan and make it easier to roll up the hose. He also highlights a benefit of using mineral spirits for cleaning oil-based sprayers: mineral spirits act as an anti-corrosive and will not freeze, even in sub-zero temperatures. This allows the sprayer to be stored outdoors without damage, ensuring it is ready for the next use. He recommends keeping oil-based and water-based sprayers separate to prevent clogging filters and gumming up hoses.

Goal: Depressurize the sprayer and prepare it for storage with mineral spirits

And I'm going to This is an oil based sprayer. So, we only use our sprayers for oil based products. If we have a latex sprayer, it's water-based. We only run water-based products. And this one is an oilbased sprayer. We only run oilbased sprayer our products through it. And if you try to run oilbased and water-based products, it has a tendency to clog the filters up and gum the hoses up and just becomes a big mess. So, it's better to not intermix them. So, I'm going to leave the mineral spirits, roll the hose up, and this thing is good to pack away for the next use. One thing good about storing the sprayer, these oilbased sprayers, too up here in Idaho in the winter time, it gets way below freezing. sometimes 20 20 below. The mineral spirits will never freeze and it's a good anti-corrosive and it won't freeze. So you don't have to worry about storing your pumps or leaving them outside in the winter time and them freezing. So last final step prior to rolling up your hose, you want to just discharge all the pressure. Squeeze the trigger. Make sure the pump is in the off position. Discharging the pressure is good for the pump to not leave it under pressure. Makes a lot easier to roll up the hose.
