I am in the middle of converting from bacquacil and yesterday the pump locked up. I bought a new pump to replace it since it was about 3 yrs old. The new one lasted 2 days and started making a loud whinning sound so i returned it figuring it was defective...Now i have been vacuming and backwashing alot from converting and just now noticed a lot of sand from where the backwash empties out. Now the new pump is starting to make some odd noises. Any ideas??? Its a wayward pump and sand filter... could the sand be getting into the pump?
Thanks for any help
