Your water pump may have ran out of pressure if you haven’t used it in the winter. Your water pump will need to be reprimed in order to function properly again. This means that water must be pumped back into the pump and driven through, which produces the pressure necessary to restart the pumping process.. For your convenience, we’ve put together a step-by-step primer on priming your water pump.

1. Make sure the power is turned off

When working on a pump, never leave it plugged in. Double-check that the pump’s power is off by checking the breaker panel and, if necessary, the pump’s sub-base.

2. Gain access to the pump system

A plumbing fixture will assist you gain access to the pump system, so the next step is to locate one near the water tank. On a pool pump, the strainer basket will serve this purpose.

3. Check for damage

Make sure that you thoroughly inspect the pump. You’ll need to inspect fittings like piping for signs of wear and tear, such as small cracks. Do these tests extensively if the system has been shut down all winter. Re-tightening of drain plugs will need to be checked for any concerns that may arise. Performing a functional test on the valves, such as turning them on and off by hand, is an excellent idea. To make sure that everything is in place, make sure that all of the hardware, such as bolts and nuts, are securely fastened.

4. Test a hose

Once you’ve located a hose, check sure it’s clean by running water through it for a few seconds. You should never drink from a garden hose that has lead in it, because it could harm your health. However, if you’re utilizing a well pump and filtering the water before and after it flows through the hose, the water should be drinkable.

5. Open the relief valves

Keep an eye on the pressure gauge as well to ensure that no pressure is building up.

6. Attach the hose

Connect the fixture to a regular water pump’s tank next to it. Place the hose into the strainer basket of the pool pump.

7. Turn on the water and wait for it to enter the tank

You should be able to hear the water filling the tank or see the water pressure gauge go up as it does so. Before closing the lid on a pool pump, make sure the strainer basket is full. When you notice water gushing out the other end of the hose, turn off the water supply.


8. Turn the power on

Allow the pump to run for about a minute before shutting it off. Wait for water to start flowing out of any relief valves you opened before closing them again. The pump is primed if it shuts itself off. If that doesn’t work, you may have to start over.

With water pumps, the most typical issue we notice is that the customer cannot prime it. Priming water pumps is quite straightforward, but there are a few things you need to keep in mind.

The suction hose and connection to the water pump must be leak-free. The pump will not prime if there is even the tiniest leak.

Before starting to prime, the pump body must be filled with water.

Ensure that all seals are intact and’sealing’ before proceeding.

How it works..

There will be no water in your water pump or suction hose when you need to use it. Pumping air through a water pump, on the other hand, will harm the pump’s seals since water lubricates and cools the seals. A centrifugal impeller is used in many petrol-powered water pumps, which are self-priming. The suction pipe of this type of water pump is pre-primed using an air-water mixture.

What is a centrifugal water pump?

It is a centrifugal pump that employs centrifugal force to create a pressure difference in the liquid it is pumping, which provides the pump’s flow rate. Consider the water-spraying action of a car tyre on a slick road. The centrifugal force, rather than the impeller blades, is responsible for the water displacement. Centrifugal pumps that are not self-priming can be used in water-filled suction lines or submerged applications because the impeller is surrounded by enough water to establish the pressure differential and allow it to pump the liquid. Standard (non-self-priming) centrifugal pumps are vulnerable to air. An air lock can occur if this sort of pump is exposed to air, causing it to cease pumping. Pumping air is far more difficult than pumping water, hence the pump is unable to force water out when there is no water around the pump impellor. The pump will not function if there is an air-lock. In order for it to work, the air must be pumped out.

How does a self-priming water pump work?

Self-priming centrifugal pumps address the problem of an air lock by mixing air with water to form a water/air fluid mix that has pumping qualities comparable to regular water. Using the suction hose, the pump is able to remove all of the air until it is simply pumping water, much like a typical centrifugal pump would. It is critical to realize that self-priming pumps require water to function. Priming holes must be drilled in order to allow air to enter and mix with water during the priming cycle. The impeller’s centrifugal force pushes water and air together into the reservoir. Water naturally sinks whereas air naturally rises. The air-free water, which is now heavier than air-laden water, returns to the impeller chamber by gravity and is ready to be mixed with additional air drawn in through the suction hose.

When pumping begins, the water in the pump is no longer recirculated. Self-priming: The pump can once again combine water and air in the casing to make pumpable fluid until completely primed again when it is restarted. While centrifugal pumps can be used to prime a suction hose by recirculating water, a self-priming pump utilizes a water reservoir built into its body for this purpose. Because of this reservoir’s capacity, the pump will self-prime every time it is turned on. The pump will not prime if it is sucking in air through a poorly fitting hose connection, so make sure your suction hose is airtight.

In addition, the pump’s seals and O rings must be water and airtight.

Do self-priming pumps work even when they’re completely dry on the inside?

A self-priming pump does not work unless it has water in the pump body. For your self-priming pump, it won’t function right out of the packaging. It won’t prime if it’s full of air. Pumps that are self-priming are able to repeatedly convert air and water into a pumpable liquid. You cannot build a vacuum from nothing! Running a water pump without water in it can cause seal failure and should never be done.
