Depending upon what type it is have you checked the bottom trap (if equipped) you open a little hatch door and unscrew the thread inside and it should flush out any debris causing this issue.
A bucket or rags would be recommended.
If not.....its a possibility your pump has failed.
What I will tell you as well... is that a good reputable company will have a guarantee or warranty on the work done as well. Others won't and will seem like opportunistic schmuck.
