There are several serious problems that come from a restricted exhaust line. Restrictions or blockages may cause the pump to malfunction by either pumping too slowly or not starting in the first place. More seriously, restriction of the exhaust line can also cause the pump to overheat and ultimately fail.
To guard against these issues, ensure the exhaust line is not blocked, either by mechanical means or by deposit build-up within the line. Implementing a regular and thorough maintenance routine will help to keep the line clear. Also, take care to position your pump in such a way that the exhaust line has sufficient room to vent.
