I had seen the information provided online by St. Isadore's Farm and decided to give one of these pumps a try, but I had no idea of the mechanics of the set up. I sent a note asking if they did direct sales and ended up, the next day, with a full explanation about pump capacities, a discussion about the distance from my barn to the pond (150 feet) with suggested hose diameter, types, aerator depth ranges, etc., as well as the name of the distributor with the lowest current pump prices for the one I was most interested in. My follow up questions were answered just as quickly. This level of customer service is rare today and should be applauded.
