Quick Answer. There are a number of reasons why a toilet may make noise after flushing; however, a loud noise that takes more than a minute after flushing the toilet may indicate a restricted water flow or a problem with water pressure. In such a case, the pressure valve should be adjusted while the toilet is making the noise.
Listen for gurgling sounds in nearby drains if the toilet continues to flush slowly. These sounds, if you hear them, mean that there isn't enough air in the waste lines to allow water to flow freely. Go on the roof and clear debris from the vent opening. Once the opening is clear, spray water into it with a garden hose.
