Pond Boss Forums AERATION Should I aerate? It may be time to aerate

From my experience, run the buried line with the least amount of joints as possible. I ran my 1" buried water line when it was hot out, and even though I blew out the water every winter, and added RV anti-freeze, I had multiple connections come apart when using stainless steel hose clamps and the grey PVC barbed connectors. I think it was because the hose shrank so much during the colder parts of the winter, and it pulled the connections apart. I had them buried about 12" below grade.

I buried some (with connections) for an air line a few years ago in late October when it was cold out. No leaks (yet).
