Some replacement fill/vent valves were replaced with the RPI valve. To make sure You are ordering the correct repair kit, you need to determine which valve you have. Simply follow the directions below to remove the valve stem and look at the size of the 2 o-rings.

If one is smaller than the other, this is the kit you need. If they are the same size, then you need to order the RCS097-841
