Just like any other mechanical equipment, it is in the nature of a pressure pump to eventually fail to work at some point as a result of regular operation. The length and frequency of downtime can be reduced through selection of the right pressure pump as well as proper installation and maintenance. That said, every pressure pump user needs to know how to troubleshoot problems with their pressure pump so that you can take appropriate action before any extensive damage can occur. Here is a useful guide to help you diagnose early signs of potential pressure pump failure in order to ensure maximum service and life: Common problems with pressure pumps that you should be on the lookout for all the time are:

1. The motor or drive not functioning properly: This may imply that it takes time to start or doesn't start at all, or makes a lot of noise while running or lacks adequate power to run at maximum speed.
2. Virtually everything seems to be functioning as usual but no water is seen coming out. This could be due to a closed suction valve or the suction strainer is blocked somewhere.
3. Excessive pressure or flow (or the lack of sufficient pressure or flow). This occurs when the volume and speed at which water comes out does not conform to the specifications of the equipment manufacturer. In most cases, this could be as a result of faulty components such as the suction line, float switch, suction valve, pressure controller unit, suction strainer, etc. Replacing the component that is out of order is normally an adequate remedy.
4. There are water leakages in one or more sections of the pump. This often takes place due to wear-out of the mechanical shaft seal, but it could also be that an O-ring seal or some other component of the pump has a crack or hole in it.
5. The pressure pump is not capable of holding prime. As you start the pump, you realise that there's no water flow into the pump to initiate the pumping process. The pump simply draws in a heap of air and then halts running. This could be caused by a range of problems both inside and outside the pump.

When it comes to performing pressure pump repair jobs, ensure you employ a professional electrician to do the job since electrical connections are often involved and you need to do all repairs correctly.
