Water was leaking from the valve/pump for the icemaker

Remove the screws that hold the old valve to the side of the refrigerator. Next, detach each plastic tube and attach that tube to the same place on the new valve, and repeat (there are many valves). Afterward, I realized that many of the plastic tubes had become brittle and had mineral deposits, so I bought additional tubing for ice makers and replaced each tube, one at a time.
