Excessive Vibration/Noise in pump

[selectstar]

I'll try the door mat suggestion. Converting sounds nasty, is it an involved process?

Actually, I did mean convert in place -- you have to replace the motor, seal, and possibly impeller. Usually, you have to add a heavy duty switch, or timer.

I never know how advanced the DIY skills are, of various posters here. Conversion in place is a moderately advanced job, costing a DIY'r ~$300 - 400, but possibly saving you $100 - 200 per year.
