New member here. We recently installed 20, Aquamaster 2 hp 220 vac fountains. The Mfg recommends motor rebuild every 3 years, as routine maintenance. We run them approx 14 hrs/day, 7 days per week. ( Turn them off for approx. 4 months in Winter ). Rebuild cost is approx : $ 850. + Pulling them out. As a retired electrical engineer, I have never seen such a short cycle rebuild. Looking for comments & recommendations
Thanks
