I recently had my house re-plumbed because of polybutylene (spelling?) leaks. I was very happy with the results except for one thing. The toilet in the master bath, when flushed, doesn't seem to drain completely. Water comes into the tank and right as the waste leaves the bowl, the water stops and it takes a long time for the bowl to fill up again. I was thinking that maybe the supply lines they used were not the same size as before. Or maybe my drain needs cleaning? I don't seem to have any problems with the water draining out of the shower or sink in the bathroom. My house is 16 years old and I have no idea if the drain has ever been cleaned. Should I call the company who did the re-pipe? Please help!
