My plumber made a mistake and installed the 503 (1.6gpf). I asked him to exchange for the ordered 504 and he said his supplier told him that people have not been happy with the 504 reporting that it often requires 2 flushes to complete the job.
Does anyone have experience with the 504 (1.1gpf) series? How does it perform?
Thanks!!!
