As always Josh was most helpful for me to diagnose the no flow alarm that we had on our system. We were able to clean and get the old sensor working but when we bought a new one to have on the shelf just in case he pointed out that we should get the PVC tee with it for just a few dollars more since they are liable to crack or break as they get older and are not available as a separate part. Always appreciate the knowledgeable advice.
