After About 20 years my pool pump has kicked the bucked. It was an A.O. Smith Model C48K2N143.
I need to order a new pump and I was wondering what would be the best replacement. My inground pool is 20" x 40"

Here is a picture of the old pump.




Can anyone recommend a supplier/brand.
Any useful tips are greatly appreciated. I wish I knew about this forum years ago.
