Pump Replacement O-Rings
After three plus years of faithful service, my lapdist pump system was beginning to bleed off pressure while I pumped and I suspected that the O-ring for the male connector was getting a bit worn.
For anyone looking for an O-ring replacement for this connector, go to Home Depot in the faucet repair section and get the 5/16 X 3/16 X 1/16 O-ring that sells for 24 cents. I would recommend using a toothpick to remove the old O-ring, so as not to damage the male connector.
Pump integrity has been restored.
