What's the best way to get RV anti-freeze out of system.

I turned on all the faucets and water outlets after filling up the fresh water tank and then run the water pump.

I also connect the municipal water supply line.

Killed a few grasses on my lawn with some spillage.:S

Too much work with anti-freeze for this lazy as$ while compressed air is such a simple process and worth the investment in entry-level Craftsman air compressor.
