My Intex sf15110 pump motor has quit. I don't think I have enough experience to repair it myself so I'm looking to replace it. I haven't been that happy with it anyhow. I don't think it ever adequately turned the water over (the pool is 20x52, holds 8500 gallons). The filter itself seems OK but is it going to support a higher hp motor? By the time I get any hose conversion parts etc. am I going to be better off buying an entire system? It needs to be something pretty reasonably priced too...
