Having a pressure washer can be incredibly helpful for cleaning a variety of surfaces, from driveways to patio furniture. However, if your pressure washer has a Delco pump, it’s important to know how to properly prime it to ensure optimal performance. Priming the pump is the process of removing any air from the system and filling it with water, which allows for smooth operation and prevents damage to the pump.

Before priming the Delco pump, it’s important to make sure the pressure washer is turned off and the water supply is disconnected. This will ensure your safety and prevent any accidental damage. Once you’ve done that, locate the inlet hose and outlet hose on the pump. The inlet hose is where the water supply connects, while the outlet hose leads to the pressure washer’s wand.

To prime the pump, attach the inlet hose to a water source and make sure it’s firmly connected. Then, open the water supply and let the water flow through the hose and into the pump. This will help remove any air trapped in the system. You may notice air bubbles coming out of the outlet hose initially, but they should eventually be replaced by a steady flow of water.

Once you see a steady flow of water coming out of the outlet hose, it’s a sign that the pump is fully primed. At this point, you can turn on the pressure washer and start using it for your cleaning tasks. It’s important to note that priming the pump may need to be done each time you use the pressure washer, especially if it hasn’t been used for a while or if there was air in the system.

Priming a Delco pump for a pressure washer is a crucial step in maintaining and using your equipment properly. By following these steps, you can ensure that your pressure washer operates smoothly and efficiently, allowing you to tackle your cleaning tasks with ease.

Locating the Prime Valve

Before you can prime a Delco pump for a pressure washer, you need to locate the prime valve. The prime valve is a small, round knob or lever that is typically located on the side or top of the pump. It may be labeled with the word “prime” or have an arrow indicating which direction to turn it. If you are having trouble finding the prime valve, refer to the owner’s manual or contact the manufacturer for assistance.

Once you have located the prime valve, make sure the pressure washer is turned off and the engine is cool. This will help prevent any accidental injuries while working on the pump. It’s also a good idea to wear gloves and protective eyewear for added safety.

Types of Prime Valves

There are different types of prime valves that may be used in Delco pumps. The most common types include:

  1. Knob-style prime valve: This type of prime valve can be turned clockwise or counterclockwise to prime the pump. It is usually located on the top of the pump and has a small handle or knob for easy gripping.
  2. Lever-style prime valve: This type of prime valve can be flipped up or down to prime the pump. It is typically located on the side of the pump and has a lever that can be easily moved with your hand.

It’s important to note that the location and type of prime valve may vary depending on the model and year of your Delco pump. Always refer to the owner’s manual or manufacturer’s instructions for specific details.

Priming the Pump

Now that you have located the prime valve and reviewed its type, you are ready to prime the Delco pump. To do this, follow these steps:

  1. Make sure the pressure washer is turned off and the engine is cool.
  2. Locate the prime valve on the pump.
  3. If the prime valve is a knob-style, turn it clockwise or counterclockwise to the prime position. If it is a lever-style, flip it up or down to the prime position.
  4. Slowly pour water or cleaning solution into the inlet of the pump.
  5. Continue adding water or cleaning solution until it begins to come out of the outlet of the pump.
  6. Turn off the prime valve by turning the knob counter-clockwise or flipping the lever back to its original position.

By following these steps, you will successfully prime your Delco pump for a pressure washer. Once the pump is primed, you can start your pressure washer and begin your cleaning tasks with ease.

Hold the trigger of the spray gun and squeeze it continuously for about 2 minutes. This will help purge any air from the pump and allow water to circulate.

Step 6:

Release the trigger of the spray gun and turn on the pressure washer. The pump should now be primed and ready to use.

Following these steps will ensure that the Delco pump is properly primed and ready to provide optimal performance for your pressure washer.

Checking for Proper Priming

To ensure that your Delco pump is properly primed, you can follow these steps:

  1. First, make sure that the water supply is turned on and that there is an adequate water flow. This is essential for proper priming.
  2. Next, check the inlet strainer for any debris or clogs. If the strainer is dirty, it can prevent water from flowing into the pump and cause priming issues.
  3. If the strainer is clean and the water flow is good, check the pump’s inlet and outlet connections for any leaks. A leaky connection can cause air to enter the system and hinder priming.
  4. Once you have confirmed that there are no leaks, locate the priming port on the pump. This port is usually labeled and can be found near the inlet connection.
  5. If your Delco pump has a manual priming port, you can use a small funnel to pour water into the port. Fill the port with water until it overflows.
  6. If your pump has an automatic priming feature, simply turn on the pump and let it run for a few minutes. The pump should automatically prime itself.
  7. After priming, check for any air bubbles or sputtering in the water flow. If you notice any air bubbles, repeat the priming process until the water flow is smooth and consistent.
  8. Finally, test your pressure washer by spraying water through the nozzle. If the water flow is strong and consistent, you have successfully primed your Delco pump.
