Couple closing questions

Number 1 what grade rv antifreeze should i get? -50 works for us in our sprayers here but didnt know if i needed some -100. Have a skimmer, main drain and 4 returns how many gallons will i need?

For clearing lines should i use a shop vac or a 400 cfm leaf blower?

Pretty sure you guys dont get below minus 50 degrees. If you want the piece of mind, splurge on the minus 100. I use a gallon per pipe.

I use my leaf blower to clear the bulk of the lines and the shop vac to get the rest. I cut a 10 ft length of garden hose, stick that into the shop vac hose and seal the connection with duct tape. I bend the tip of the garden hose and can usually snake it pretty far into the pipes. I suck out what i can and then put a gallon per pipe of antifreeze in before capping them.

Shop vac is preferred, -50 RV antifreeze is perfect.
