2/23/2024 0 Comments Kohler tub waste and overflowI have all of the part numbers now for the assembly. The guy pulled out his old Kohler manuals and found my assembly on the first page of his oldest book on his shelves. I wound up buying a drain key and popping the drain out to bring with me to a shop. Every shop I called treated me like a fool who was measuring the diameter of the flange. The threaded portion is 2" not 1 1/2" like the new standard is. ***./asp/product_detail.asp?item_no=DCB-BLT-20W ***./asp/product_detail.asp?item_no=DCB-BLT-20A A little bit of searching on my own yielded two results.but I am unsure if by 2" then mean a 2" thread or if they are just taking a topside flange measurement. The way I see it, if you are insistent on keeping the old tub, you can talk to a machinist about fabricating some sort of adapter flange plates which you can silicone into place between the tub and the male drain fitting and then again on the bottom of the tub between the female drain fitting and the tub, or you can keep searching the net in hopes of finding a replacement part. In either case, by the time it becomes necessary to work on the drain systems for such old units, the tubs are usually damaged and/or rusted enough to require replacing, which makes finding repairs parts for antique plumbing fixtures even more difficult, like Hj said. I think "HJ" needs to also caveat his forum entries with "Master Heckler".Īre you sure the old tub drain was actually a 2" outlet using 2" piping? Or was it a 1.5" outlet that just had a wider flange than current units? The reason I joined this forum was to get some useful assistance from master plumbers. I am not a plumber, much less a master plumber, so I guess I didn't think that my tub drain was so unique. The tub is still in great condition but just trying to "update" it a little. I have a 1940 tub drain I need to replace also. I guess I would be the SECOND idiot in the world that needs to replace a 1940 era tub drain (I would have bet money they built more than two homes in the world in the year 1940) so me and Husky Dad are slowly starting to create a new 2" tub drain market. They are in the business of making money, and to do THAT, they make things." As my economics professor once said, companies are NOT in the business of making things. Manufacturers ONLY make things they can sell, and sell a lot of. If that had been the case, you would also be out of luck. My answer was the same as if you had asked for a 4" sink strainer for an old Kohler sink. What did you want me to say? "I appreciate your problem, and if I EVER find someone who makes such an item, I will refer them to you?" The Internet may be "wonderful", but it is not a miracle worker. I DO KNOW, because there is absolutely NO REASON for any company to produce a 2" drain assembly. In those days some manufacturers, such a Kohler, DID make tubs with oversized holes, BUT they still used 1 1/2" drains, the fittings at the tubs were just larger.
