I have a 1 1/2 HP Whisperflo pump that was installed with new pool back in 2002. It has always run quiet with no problems. When it kicked on last night there was a loud metallic scraping sound that I could hear from in the house. I went out and it sounded like it was coming from right by the basket end of the assembly by where the impeller is located. The pump is still working fine as far as circulating water through the system and the filter pressure is normal. The motor doesn't appear to be laboring. Just the loud scraping noise.
Knowing these symptoms, where should I be looking first? Everything I read seems to indicate that if it was just the impeller or diffuser it would not be keeping prime. Is a pump this old worth messing with or should I start looking for a new one?
Thanks in advance for any direction you can give.
