Threads on pop-up drain pipe are not long enough to accommodate the thickness of an old porcelain sink with overflow, making installation impossible without replacing the sink or using the original setup.
Existing pop-up drains are not designed with adjustable or extra-long threads to fit older, thicker sinks with overflow, forcing users to either modify the sink or revert to outdated hardware.
