Hi -
I'm working with a 1954-dated Case 2-piece toilet for which I can find no description, parts or diagrams. Inside of tank lid says Case and also Robinson. I've never seen anything quite like it.
The tank is attached to the bowl by a single 7/16" stud that comes from center of the bottom of the flush valve and protrudes thru a tank-to-bowl gasket, thru the bowl inflow opening and out a single hole in the center of the bowl flange under the bowl's water entry hole. This attaching stud pulls the tank down to the bowl and is held in place and secured to the bowl with a large rubber washer/gasket, then a washer, and below that a hex nut, which apparently requires thread sealer on it to prevent slight leaks during the tank draining/flush interval. This is the only "bolt" attaching the tank to the bowl.
The flush valve is seated normally with a lipped gasket in the bottom of the tank. But instead of a 2 1/8" flange nut with six flats below it to pull it down into the tank bottom, there is a round brass "nut" threaded 2 1/8" inside, smooth on the outside perimeter with NO outer flats, and with an inward taper like a tapered compression gasket. Attached to this ring/nut, and part of it, are two descending legs that meet below (like a "V") in a threaded section from which the single tank attaching stud protrudes.
It looks somewhat like a Case SP-29 flush valve which has an attaching nut resembling an upside-down wing nut with long wings. In my case, however, this 2 1/8" inside threaded tapered ring/nut IS the attaching nut and it looks like the lower half of an SP-29 without the "wing nut" below it.
The tank-to-bowl gasket, which I need, is probably about 3" inside diameter, 3/8" to 1/2" thick, and 3 3/4" outside diameter. Top and bottom are flat, the outside diameter surface is flat (perpendicular to top and bottom, while the inside diameter is beveled to match the inward taper of the previously described ring/nut that secures the flush valve into the tank. I hope this makes sense - I would provide a photo but I had to reassemble with the badly deteriorated gasket.
Can anyone provide a more accurate brand/model toilet for what I have described, and can anyone direct me to a source for the gasket I need. I have explored numerous sites for Case toilet parts and have found nothing resembling what I have.
Thanks in advance!
