If you have a sprinkler pump in your lawn, then you must know how annoying it can get, even the newly purchased ones. You might wonder why your brand-new sprinkler pump is not working, whether the problem is with the manufacturing or something you did wrong while assembling.
However, this happens when your sprinkler loses prime. It uses centrifugal force to pump out water through a smaller pipe. In the process, it creates pressure to keep up the water flow. So, if vapor or air gets on the water path, it starts losing the water pressure, in other words, prime.
It is a cry for help from your pump because if it happens too often, you might see a sub-par performance from the pump even when the motor keeps running, which ends up burning it out. So, you need to prime your pump immediately, or it will cost you.
So, I’m here to give you a detailed account of how to prime a sprinkler pump, and you can get rid of this problem all by yourself.
Note: Shut off all the electric power before you begin to make sure you don’t harm yourself.

How to Prime a Sprinkler Pump: Step by Step
I’ll explain all the actions you must take to get your pump back in the game. Let’s get into it.
1. Inspecting the Pump Thoroughly
The very first step is to take a tour in and out of your pump, especially inspect all the valves and hose connections. If you see any problem in these areas, you need to fix them before you proceed with priming.
When I was about to prime my sprinkler, I didn’t think of checking out these issues, but later I found out my pump was not working because some debris was already in the water intake line. Nothing happened inside the pump casing.
2. Shut the Drain Valve
Close the drain valves with a wrench if you are done testing. However, if your pump does not have a drain valve, you need to place a foot valve instead.
If you are using a stream water source, then attach a foot valve underneath the intake hose. The most efficient way to filter out the debris from the system is to keep draining water while the pump motor is turned off.
3. Disconnecting Hosepipe
The next step is to detach the opposite end of the hose from the motor because you need to fill this part with water before you start. This phase is crucial because it gives enough space for air to escape when you water the intake hose line.
You can do it very quickly by plugging a fixture at the end of this hosepipe.
4. Turn on The Water to Fill the Priming Port
Now take a funnel or a garden hose to fill the pump through the sprinkler head. You can also use any other tools such as hand-pump to continue this step. Make sure you are doing it correctly because there should be no air pockets.
If the pump housing remains empty, the priming will remain susceptible to interruption.
5. Disconnect the Water Source
Turn off the water if your pump is filled up but do not disconnect the garden hose. It would help if you lifted the foot valve to prevent the water from draining out from the pump.
When I was a beginner, I made the same mistake by not holding the valve properly. Eventually, some of the water came out of the pump, and I had to fill it up one more time.
6. Close the Lid
Now hold the foot valve in the air and start screwing it. Make sure you secure it properly. Once it is done, the pump system will not be drained out of a single drop of water, and you are almost there to prime your pump.
7. Turn on The Power System
Disconnect the water hose from the pump. Now your pump’s intake hose is full of water, so you are ready to turn the motor on.
Turn on the pump. You might see a minor kick once it starts. There is nothing to worry about because it can happen due to a pushing-out of the system’s residual air.
8. Wait Until the Pump Completes Its Cycle
Gradually, the air gets out of the pump with the flow of water. If you still find the presence of air inside the pump, repeat this procedure one more time.
Finally, do not forget to close the priming port and the pump housing after you finish. Also, attach the intake line to the primary water source and check whether your irrigation pump is working or not.
How To Prime A Sprinkler Pump From A Lake
Many of us have a lawn sprinkler that uses a pool or lake as a source of water instead of a tank. So, people wonder how they can prime their pump from a lake? It is effortless and pretty much the same as before.
So, first of all, you have to check the connection of the plumbing fixture and the filter to ensure steady water flow. Then, the procedure is straightforward.
Inspect the system damage, prepare a hose, open the check valve, and fill the system with clean water. If you are planning to use water from the lake, then you must have a strainer basket or a filter positioned inside the pool.
Likewise, keep pouring the pump until it’s full. Close of the valves in case any of them remain open.
Finally, turn on the motor and wait a few minutes because the pump might adjust the pressure before it begins self-priming.
Note: Priming is necessary not only to get rid of the air but also to increase your pump’s functionality. So, you can do it once before every season to keep a steady flow of water and reduce the chance of damaging the motor.
Ready to Prime?
Running the pump without priming is a risky business because it damages the motor and reduces its lifespan. The pump will start sounding different if it has air flowing with the water source.
It would be best if you prime your pump from time to time to eliminate the danger of burning out the engine. Besides, priming is a must for better irrigation. So, I hope my two cents on to prime a sprinkler pump can work as a blueprint for anyone who is having trouble getting the most out of their pump.
Note: Do not hesitate to visit technicians if you still face any trouble.
