Called out to due to high pitched noise at recirculating pump that seems to happen randomly. Couldn’t make it happen again myself, but with some assistance found out it was the bearing inside the recirc pump that will make that noise. Pump is original to home as we did not replace it with water heater. Pump also runs 24/7 with no timer setting. Pump is working but it will make that noise more and more frequently and then just stop working. Left estimate for pump replacement with timer setting.
