Learned valuable lesson putting off impeller inspection/replacement. Here are B4 and after shots. I bought 252 in October and I believe it was last replaced 6 years ago... dodged a bullet. Went Hardin Marine pump route with new pulley and impeller maintenance kit for next time. Pressure is up and temp is down 2-3 degrees.
