Hello, my existing booster pump crapped out on me. I have owned the pool for 2 years so im not quite sure how old it was, but it looked pretty weathered and just stopped working the other day. I purchased a replacement and installed it identically to the previous. The replacement is pretty loud and clunky sounding, runs hot after a minute and shuts off. When it is running the Polaris operates just fine. What could my issue be? Bad pump?
