I am trying to replace a couple of hose outlets with frost free sill cocks. Existing are hose bibb sweated to 1/2" copper. The hole through the poured foundation is about 3/4" in diameter and needs to be 1 1/8" in diameter for the sill cock install.

Any suggestions on how to ream out the hole to the larger size? the concrete is older (1920 vintage house) and about 10" thick.

I may have the option to raise the position of the sill cock about 12" and go through the brick and box joist. I could plug the old hole with some hydraulic cement.

Ideas?

Thanks,

Joel
