I just got my pump running this season. It spent the winter out in the elements and not covered. I am hearing occasional metallic pinging sounds maybe a momentary metallic scratch. I believe it is on the dry end. I checked to make sure the impeller was cleared.
Any ideas on what this is? Should I be running it?
I have a new variable speed pump in the box. I was going to replace it after the pool has had its spring break-in.
