Journeyman - For pond aerator life span and rebuilds for the Hiblow - get back to me after 20 years of operation and then we can talk about rebuilds and pump reliability. I know Hiblow makes quality compressors because I have one, but I am not sure yet that 8ft+ depth is their designed or engineered intended usages. If you look at the link you provided, the company specification charts and in the user feedback Hiblow recommends the 100 and 120 pumps operate optimum at 5.14 feet deep(2.57psi). The pumps will operate in deeper water but they suggest they will not perform as well as at 5.14ft.
