looks like kohler to me.
you read my mind, Yes there should be an imprint on the back
I use mirror to see under the valve is "ASSE, TYPE P, 1006" what it mean?
Were talking semantics here so cool it mouse.the #s you need should be printed on the top of the valve in ink, not stamped or embossed. example: 78655 and time stamp: May 09, 2008
look over the rest of the valve.
Sorry mouse please except my apology I thought you were some one else that is a total AH.huh???? whatchoo smokin'?
This particular one is 1 9/16" insidethe valve or cartridge diameter is 1-3/4 inch, is Premier same? Delta is 2 inch.
