Thanks Al. I got down to the impeller but couldn't get it off. I didn't realize I had to remove the screws at the back of the motor and then put something in the shaft to keep it from moving to get it off. I'm going to give that a try and get the impeller off and take the whole motor apart to see if I notice anything. I'm going to clean it well because I'm guessing there is something in there impeding it from rotating properly.

I talked to a friend of mine who works on motors/generators/turbines and ran my thoughts by him on the impeller and it not rotating right would that cause the flow to be off. He asked about the normal psi and I said 15-20 but it's running about 8-10. It's half of what it should be. He said it could be that. Off to give it a try now and see if it works to fix the problem. Will report back in a bit.
