I have an Intex swg/sand pump. It was working fine until yesterday. It quit running. It was over heated and smelled weird. I was blowing out the bottom with air compressor to make sure the vents were clear. I could here something blowing around in the case. I removed the screws for the cover, couldn't completely remove cover. Two things fell out, four square, clear pieces of plastic AND chunks of a small snake. Is there an internal cooling fan in the case? Did the snake kill my pump? Thanks for any help!
