Many people find themselves in this situation and this blog will provide you with the necessary steps to do it safely and effectively.
Understanding Pressure Washer Pumps
In this blog post, we will discuss how to drain water from a pressure washer pump. But before that, let’s dive deeper into what pressure washer pumps are, how they work, and the different types of pumps available in the market. By the end of this section, you’ll have a better understanding of pressure washer pumps and their importance in pressure washing systems.
Types of pressure washer pumps
The main types of pressure washer pumps are axial cam pumps, triplex plunger pumps, and wobble plate pumps. Axial cam pumps are the most common and affordable type, but they are also the least durable. Triplex plunger pumps are more durable and efficient, making them a good choice for heavy-duty use.
Wobble plate pumps are similar to axial cam pumps, but they have a more compact design and are better suited for light-duty applications. Understanding the differences between these pump types can help you choose the right one for your pressure washer and ensure proper maintenance and operation.
Main components of a pressure washer pump
The main components of a pressure washer pump include the inlet and outlet valves, pressure relief valve, unloader valve, pump head, and plungers. These components work together to create the pressure needed to push water through the pressure washer’s nozzle.
Understanding how these components function is essential to properly maintain and repair a pressure washer pump.
How a pressure washer pump works
A pressure washer pump works by creating high pressure through a combination of water flow and mechanical force. When water flows into the pump, it passes through an inlet valve and into a chamber where it is pressurized by a piston or plunger.
The pressurized water is then forced out through an outlet valve and into the high-pressure hose. The cycle repeats as long as the trigger on the pressure washer gun is pressed, creating a continuous stream of high-pressure water.
To drain water from the pump, the first step is to turn off the pressure washer and release any pressure in the system. Then, remove the inlet and outlet hoses from the pump and tilt the pressure washer so that the pump is facing downward. Any remaining water will drain out of the pump, and it can be stored safely until the next use.
When to Drain Water from a Pressure Washer Pump
Using a pressure washer without proper maintenance can lead to pump damage and reduce its performance. One important maintenance task for pressure washers is draining water from the pump. Below, we are discussing when to drain water from a pressure washer pump and why do so. We will also provide a step-by-step guide on how to drain water from the pump to ensure that your pressure washer is always in optimal working condition.
Seasonal storage preparation
Properly preparing your pressure washer for seasonal storage is crucial for its longevity and performance. As part of this process, draining the water from the pump is essential. Before storing your pressure washer during the off-season, ensure that you have removed all water from the pump to prevent freezing and potential damage.
Simply disconnect the water supply and engage the trigger gun to release any remaining water. By taking this precautionary step, you can safeguard your pressure washer and be ready for its optimal performance when the season starts again.
Extended periods of inactivity
When a pressure washer pump is not being used for an extended period of time, drain the water from the pump to prevent damage. Water left in the pump can freeze and expand, causing cracks and other damage.
Draining the pump also helps to prevent buildup of mineral deposits and other contaminants that can clog the pump or cause it to malfunction. To drain the pump, turn off the pressure washer and disconnect the hose and wand.
Hold the spray gun trigger until all water has been expelled from the pump. It is recommended to drain the pump after each use to extend the life of the pressure washer.
Preventing freezing and potential damage
To prevent freezing and potential damage to your pressure washer pump, drain any water remaining inside the pump after use, especially if temperatures drop below freezing. This will help prevent any water from freezing and expanding, potentially causing damage to the pump.
It’s recommended to drain the pump after every use, and to also use a pump antifreeze solution if you live in an area with particularly cold temperatures.
After chemical usage
It’s essential to drain the water after using chemicals to prevent corrosion and damage to the pump. The chemicals can create a buildup of residue in the pump, leading to reduced performance and potential damage.
Therefore, it’s crucial to drain the water from the pump after using chemicals to ensure the longevity of your pressure washer.
Step by Step Guide to Draining Water from a Pressure Washer Pump
One common maintenance task is draining water from the pressure washer pump. This is important because leaving water in the pump can lead to freezing and cracking during colder months, as well as the build-up of sediment and minerals that can damage the pump over time. Following is the process of draining water from a pressure washer pump so that you can keep your machine running smoothly for years to come.
Disconnecting the pressure washer from power sources
In order to safely and effectively drain water from a pressure washer pump, it is essential to disconnect the unit from all power sources. This includes unplugging the power cord and turning off any fuel sources such as gasoline or propane.
Failing to disconnect the power source can lead to electric shock or other hazards. Once the power is disconnected, the next steps in draining the pump can be taken.
Releasing pressure from the system
Releasing pressure from the system is an essential step in draining water from a pressure washer pump. This can be done by turning off the machine and pulling the trigger on the spray gun to release any remaining pressure. Take caution and wear protective gear when performing this step to avoid injury.
Removing hoses and attachments
When draining water from a pressure washer pump, remove all hoses and attachments to ensure that all water is properly drained. This step is crucial in preventing any water from freezing and causing damage to the pump during colder temperatures.
It is recommended to disconnect the inlet hose, high-pressure hose, and any other attachments before proceeding with the draining process.
Draining water from the pump
Draining water from a pressure washer pump is important to prevent damage caused by freezing or corrosion. To drain the pump, you need to turn off the pressure washer, disconnect the water source, and remove any remaining water by either using the pressure washer’s drain valve or tilting the pump to remove excess water.
It’s also recommended to flush the pump with a cleaning solution to remove any built-up dirt or debris. Properly draining and maintaining your pressure washer pump can help prolong its lifespan and ensure efficient performance.
Flushing and cleaning the pump
To ensure that your pressure washer pump is working efficiently and to extend its lifespan, regularly flush and clean it. Flushing the pump involves removing any remaining water and cleaning it to prevent buildup of dirt and debris.
This can be done by attaching a hose to the pump and running water through it. Cleaning the pump involves disassembling and removing any buildup of dirt and debris from its various parts, including the valves, inlet, and outlet.
Follow the manufacturer’s instructions when cleaning the pump to avoid damaging any of its components. Regularly flushing and cleaning the pump can prevent clogging and ensure that your pressure washer works effectively.
Additional Maintenance Tips for Pressure Washer Pumps
Water left inside the pump can freeze and cause damage, so properly drain the pump after each use. Following are additional maintenance tips for pressure washer pumps, including step-by-step instructions on how to properly drain water from your pump.
