I recently replaced my 44 year old well pump with a new Goulds J5 convertible deep well jet pump. The pump seems to run pretty smooth but is pretty noisy. It seems to transmit vibration through the copper discharge pipe. This seems strange because if you put your hand on the pump when it's running it feels smooth but if you grab the 3/4" copper pipe going to the rest of the house there is a pretty significant vibration. The first thing I tried was to put rubber vibration pads under the feet of the pump. That didn't work. I notice there are bolt holes in the pump feet. Do you think lagging the pump to the concrete floor would help? The old Goulds pump when it was running good a few years ago was much quieter. Even toward the end when it started making more noise from the impeller the sound didn't travel through the pipes like this one. I didn't change much with the new installation. I pretty much just swapped out the pumps. Any suggestions?
