When I installed the valve, it leaked. I probably should have returned it but I took the new one apart and compared it to my existing valve and found that the original one had a round gasket and the new one did not. I used the ring from the original in the replacement valve - the leak stopped and the valve worked.
Not sure how it passed QA before shipment since it leaked when installed.
Maybe it was just a one time slip, but the valve did work as a replacement to the original which is why i gave it a 3.
