发帖数: 4414 | 7 " there are some claims of irrigation systems being self-draining. This
might be true, however is it worth the gamble? Drains can get clogged or
water can be trapped in low spots; the list goes on and on. For the added
safety and fairly low cost of winterizing with an air compressor, it's not
worth the gamble. Blowing out our irrigation system with an air compressor
has been proven to be the best method being used today."
