    I always use RV antifreeze without any problems.

    I would say no. I would be afraid that I wouldn't be able to get it all out. What about using windshield washer fluid for sub-zero temps? Perma green ships with that in their tanks from factory.

    Rv antifreeze, have used for years on all types of tanks, works fine! Just do normal rinse come spring. Far cheaper than replacing a pump or having pvc cracking where moisture sits.

    RV antifreeze here, too. The windshiled washer idea is interesting, but I've never had an issue using RV. In fact, back in the day I used regular green antifreeze, but when I worked at Davey, they suggested using RV, as plant injury was not as likely.

    How much of the RV Antifreeze would you use in a 200 gallon tank? How much does this stuff cost? Does the antifreeze cause any problems to the lawn?

    Just enough t fill the pump and hoses. A few gals. should be good. Rinse it thoroughly before use in spring. Any residue will be so diluted with 200 gals. of water, it won't matter.

    You can do one of two things. You can take off the intake side of the pump if it's accesable, and pour the antifreeze in as you pull the starter rope slowly. Continue until it comes out the discharge side of the pump. Then use an air compressor to blow out all lines and hoses, etc... You'll use very little antifreeze with this method. Or, empty the tank and pour several gallons into the tank and run all lines, guns, agitation, etc... until the anitfreeze is thoroughly distributed though the system. Takes more anitfreeze, but it's a little easier.

    Regular antifreeze is tough on grass-kills it. Use the RV type. Or use windshield anti-freeze. Either way, save it for reuse next year. Just do not dilute it with water (much). And be careful to not spray it on the grass.
