If you live in a cold environment don't forget to make sure all the water is out of it before winter hit's or run some RV pipe antifreeze in it. Otherwise It can freeze and damage the pump. Don't run it dry to get the water out either you will melt the seals.
I just turn mine off and squeeze the trigger to get it out of the lines. Then for storage I use pump saver or whatever it's called. Wait until it runs out the end of the nozzle. First use I make sure to run it for a while to make sure all that is out before using it on anything.
