I opened my pool Friday. There was a layer of “dust” on the bottom. I sucked it up with the vacuum. My pump sounded normal from the time I started it to the time I backwashed it for the 1st time. During backwash the pump started to be louder then normal. I finished the backwash and unscrewed the container to the pump basket. The basket was filled with the pollen dust and gunk. So much so that the strainer basket held water.

When I put everything back together and ran the pump, it was loud again. It is twice as loud as normal.

Also, I have my backwash line running to 1.5 inch pvc pipe underground to the back of my yard, about 100 feet. (This is the set up I have used for the last 2 seasons)

My pump and filter only has 2 full swim seasons on it.

Anyone know what happened to my pump?
