Slow water/noisy pump

The water seemed really slow at the kitchen sink during our last overnight, and the pump sound was clunky. Decided to tackle it yesterday. I had never noticed the strainer on the pump inlet before, and decided to start there. With the winterizing hose plugged, I moved the valve to the winterizing position so that I wouldn't need to drain the tank; then unscrewed the strainer. There was a bit of debris, mostly plastic that I figure must have been from the tank assembly in '18. I cleaned and re-assembled the strainer and ... no joy. Next I decided to look at voltage. With no clear way to check at the pump, I checked at the fuse. Looked good. I thought of checking voltage further at the switch, but decided to look at the kitchen sink aerator first. Again I found a bit of stuff, which didn't seem enough to make a difference. It did in fact make a big difference. The flow is much better and the pump runs smoothly. Just thought I'd mention this little journey in case someone else has a similar issue. Happy New Year.
