I put the first filter in service and it started leaking with in the first hour . I removed it and checked the o ring and they appeared to be in good condition. I put a small amount of petroleum jelly on the o rings and reinstalled the unit. Next morning there was a puddle of water in front of the fridge.
  At the point I installed the second filter and it is doing fine. I would not recommend this filter.
