Identifying Tub Shower cartridge, Source for the BNK7005
I am the maintenance man at an old folks home. 50 apartments have the same one handled Tub/Shower fitting. There is no brand name on the fitting just the certification stamps. I need to identify the cartridge in the Lift and Turn fitting so I can order replacements. Please see attached pictures. The number on the cartridge is 08 03 036 (though the last may be 03G) with US Pat # 6.123.105 and other Pat # 138.454
I'd be grateful for any ideas.
