    I used a die to pull the brass collar out of the iron elbow. Had to put the elbow in a vice and tap on the vice grip that was clamped onto the square end of the die. It was tight. It goes in snug, and the raised collar will clamp it in when I press the sleeve back into the elbow. You get one chance to do it right. It's the last duckbill the seller had, so claimed on the web site.

    I'll squeeze it into place with a small vice. (Don't think I'll need a 20-ton press for this job.) It's not that big a deal, you could almost just tap it in with a little hammer (preferably not a big hammer).

    The end of the brass sleeve that has a raised "collar" is the outlet end. The duckbill goes into the non-collared end of the brass sleeve, bill end first, and it's held in the sleeve by an internal ledge in the sleeve. i.e. the ledge catches the rim of the duckbill. The flat "bill" end of the duckbill valve has a tiny hole and points out of the elbow. This results in a one-way "check" valve, letting oil go to the bar, but not back to the source.

    I hope I'm not beating this subject to death. Just thought the next person that comes along, clueless like me, could benefit from my experience.

    I haven't put things back together yet, but will update when I get a chance. Need to go finish tiling the shower for now.

    This picture shows the ledge inside that the rim of the duckbill rest against when inserted bill first.

    The junk inside is residue from the original duckbill check valve. Probably was a rubber part that disintegrated.

    This photo show the thread left from the tap that I used to extract the sleeve, and the collared end of the sleeve is on the outlet opening of the elbow. In other words, this is the way you line it up and stick it in, the duckbill having been inserted in the left end of the sleeve as shown. I hope that's clear as mud. Anyway, just another fun picture.
