A Complete Guideline on How to Maintain Water Pumps

Water pumps are vital machines that are essential for almost every home as it distributes water at various locations of the house. While buying a water pump it is equally important to get a thorough guideline about its maintenance process. This is because when a pump runs at its peak efficiency, it uses less fuel, experiences less downtime, and obviously costs less to operate. So, buying a pump is not only an investment, the time you spend on its maintenance is also an investment as it adds to the lifetime performance and value of the machine. There are many ways to take care of your pump. Read this blog to know some of them.

1. Take care of the pump flow

Take regular notice of the discharge flow of the pump. Is it taking a longer time to do the same job than it used to do? Consider the reasons behind the decreased flow of the pump. It may be caused by a collapsed suction hose lining, a leaking gasket, a wedged suction line or a damaged or worn impeller or wear plate. To determine the cause of the decreased flow, the discharged pressure and the suction vacuum of the pump must be measured while the pump is operating. Measure these two aspects of the pump at start up and compare the latest readings with that of the originally recorded ones. Remember a vital point here. While troubleshooting a pump, always follow the high abnormal reading. A high discharge pressure will indicate a decrease in a suction vacuum which could be a sign of clogged or partially clogged discharge line.  It also may be a sign of a closed valve or trapped air unable to evacuate or any obstruction outboard of the point where the gauge was installed into the discharge line. It is common practice to install gauges approximately two to four pipe diameters from the pump. If both the gauges decrease, the problem can be located between them, inside the pump. A clog in the eye of the impeller, wear, wide clearances or air into the suction line can be the reason for decreased gauge readings.

2. Take care of the sound of the pump   

Always notice the type of sound created by the pump. Is it sounding like marbles rattling in a can? Then it can be the indication of cavitations and could be caused by a suction lift that is too high for the pump or a suction hose that is too long or has a collapsed lining. The noise of the pump should be mechanical or hydraulic. Run the pump briefly without water. If the noise is no longer present, it is hydraulic in nature. If the noise is present, it is mechanical in nature.

3. Check if the pump is clogging to frequently

To maintain a god health of the pump, keep a note whether it is clogging frequently or not. If the pump’s suction check valve is clogged, it may be because of the strainer which might be too large or too small. There is also a high chance that the strainer might be stuck in mud thereby plugging the suction line.

4. Check if the pump is overheating

Another key factor to maintaining water pumps in Melbourne is to prevent it from overheating. This may be due to the restriction of liquid flowing in or out of the pump. Check of improper impeller clearance which might be the reason of overheated pump. The suction strainer may be clogged or the pump’s ability to handle air through an air release line, air release valve or open-ended discharge line may be obstructed. Here is a word of caution. Never open a hot pump for maintenance. Allow the pump to cool before opening. Please note there may be lingering pressure inside the volute casing ever after the pump has cooled off.

Lastly, it will always be better to conduct regular maintenance of water pumps if you want to enjoy good returns on investment. It will always be better to avail services from professionals to maintain water pumps and pump covers in Melbourne.
