Why Pump Saver For Pressure Washer Is Necessary
From my experience, using a pump saver for my pressure washer has been a game-changer. The pump is the heart of the machine, and without proper care, it can wear out quickly. The pump saver protects the internal seals and valves from drying out and cracking, especially during periods of inactivity. I’ve noticed that when I don’t use a pump saver, my pump develops leaks or loses pressure much faster.
Another reason I rely on a pump saver is that it helps prevent freezing damage in colder weather. Water left inside the pump can freeze and expand, causing serious damage. The pump saver solution displaces the water and lubricates the pump parts, so I don’t have to worry about costly repairs when winter comes.
Overall, using a pump saver is a simple step that extends the life of my pressure washer, saves me money, and keeps my machine ready to go whenever I need it. From my perspective, it’s an essential part of maintenance that every pressure washer owner should consider.
My Buying Guides on Pump Saver For Pressure Washer
When I first started using a pressure washer regularly, I quickly realized how important it was to protect the pump. A pump saver is a simple yet essential accessory that helps prolong the life of your pressure washer’s pump. Here’s what I’ve learned through my experience and research to help you choose the right pump saver for your needs.
What Is a Pump Saver and Why Do I Need One?
A pump saver is a product designed to maintain and protect the internal seals and components of your pressure washer pump. After I started using mine, I noticed that the pump saver prevents corrosion, lubricates the seals, and removes moisture that can cause damage when the pressure washer is stored. Without it, pumps can become stiff, leak, or fail prematurely.
Types of Pump Savers I’ve Tried
There are mainly two types of pump savers: chemical formulations and mechanical devices.
- Chemical Pump Savers: These are liquids you pump into the system after use. I found them easy to use and effective at lubricating and protecting the seals.
- Mechanical Pump Savers: These devices pressurize the pump with air or a small amount of fluid to keep seals compressed and prevent drying out. They are often used for long-term storage.
For everyday use and storage, I prefer chemical pump savers because of their convenience.
Key Features I Look For in a Pump Saver
When selecting a pump saver, I focus on these features:
- Compatibility: Make sure it works with your pressure washer’s brand and pump type. Some pump savers are universal, while others are brand-specific.
- Ease of Use: I want something simple to inject into the system without complicated steps or extra tools.
- Seal Protection: The formula should be designed specifically for the seals in pressure washer pumps to prevent drying and cracking.
- Corrosion Inhibitor: I look for pump savers that protect against rust and corrosion inside the pump.
- Storage Life: If I’m storing the pressure washer for months, the pump saver should provide long-lasting protection.
How to Use a Pump Saver Effectively
From my experience, the best results come from following the instructions carefully:
- Run the Pressure Washer: I run it for a few minutes with clean water to flush out debris.
- Turn Off and Disconnect: I turn off the machine and disconnect the hose.
- Inject the Pump Saver: Using the pump saver’s applicator or a pump saver gun, I inject the solution into the water inlet or pump as directed.
- Run the Pump Briefly: Sometimes running the pump for a few seconds circulates the solution and coats the internal components.
- Store Properly: I store the pressure washer in a dry place to maximize protection.
My Recommended Brands and Products
Over time, I’ve found a few brands that consistently deliver quality pump savers:
- Briggs & Stratton Pump Saver: Great for many gas-powered washers, easy to use.
- Simpson Pump Saver: A trusted name with effective seal protection.
- General Pump Saver: Works well for various brands and offers good corrosion protection.
Always check if the product suits your specific pressure washer model.
Final Tips from My Experience
- Don’t skip using a pump saver, especially if you don’t use your pressure washer frequently.
- Use the right amount as recommended—too little won’t protect, too much can cause issues.
- Regular maintenance combined with a pump saver extends your pump’s life significantly.
I hope my buying guide helps you choose the best pump saver for your pressure washer and keeps your equipment running smoothly for years to come!
