Why Pressure Washer Pump Saver Is Necessary
From my experience, using a pressure washer pump saver has been a game-changer in maintaining my equipment. After each use, water can sit inside the pump and cause rust or corrosion over time. The pump saver solution helps by lubricating the internal seals and preventing any moisture buildup, which significantly extends the life of my pressure washer.
I’ve also noticed that without a pump saver, the seals can dry out and crack, leading to costly repairs. By applying the pump saver, I ensure that the seals stay well-conditioned and flexible, reducing the risk of leaks. It’s a simple step that saves me money and keeps my pressure washer running smoothly for years.
Overall, using a pump saver is a small investment that protects my equipment from damage caused by inactivity and harsh elements. It gives me peace of mind knowing my pressure washer is ready to go whenever I need it.
My Buying Guides on Pressure Washer Pump Saver
When I first started using my pressure washer regularly, I quickly realized how important it was to protect the pump. That’s when I discovered the value of a Pressure Washer Pump Saver. If you’re like me and want to extend the life of your equipment while keeping it running smoothly, here’s what I learned from my experience.
What Is a Pressure Washer Pump Saver?
A Pressure Washer Pump Saver is a specially formulated solution designed to protect your pressure washer’s pump from damage caused by rust, corrosion, and freezing. It helps maintain the internal components, especially during periods of inactivity or cold weather. After learning this, I never run my pressure washer without using it.
Why You Need One
From my experience, not using a pump saver can lead to costly repairs or even the need to replace the pump entirely. If water sits inside the pump and freezes, it can crack the seals and damage the internal parts. The pump saver prevents this by displacing water and lubricating the pump components, which keeps everything in good condition.
Key Features to Look For
When I was choosing a pump saver, I focused on these important features:
- Compatibility: Make sure the pump saver is suitable for your pressure washer model and pump type (e.g., triplex or axial cam).
- Freeze Protection: If you live in a cold climate like I do, pick a product with strong freeze protection to prevent ice damage.
- Lubrication: A good pump saver lubricates seals and other moving parts, reducing wear and tear.
- Corrosion Resistance: It should protect against rust and corrosion to extend pump life.
- Ease of Use: I prefer a product that’s easy to apply without complicated steps or extra tools.
How to Use a Pressure Washer Pump Saver
From my routine, here’s the simple process I follow to use a pump saver effectively:
- Run the pressure washer for a few minutes to warm up the pump.
- Turn off the engine and disconnect the water supply.
- Attach the pump saver bottle to the pump’s water inlet.
- Squeeze the bottle until the solution fills the pump and comes out of the discharge port.
- Store the pressure washer in a dry place until next use.
Doing this after every use during the off-season or long breaks has saved me from many potential repairs.
Top Brands I Recommend
After trying a few options, these brands stood out to me for their reliability and effectiveness:
- Briggs & Stratton Pump Saver: Trusted and widely recommended, great for various models.
- Simpson Pump Saver: Known for excellent freeze protection and lubrication.
- MTM Hydro Pump Saver: Affordable and easy to use, perfect for casual users like me.
Final Tips from My Experience
- Always use the pump saver before storing your pressure washer for extended periods.
- Follow the manufacturer’s instructions carefully for best results.
- Don’t skip this step, even if you think you’ll use the washer again soon—prevention is better than repair.
- Consider keeping an extra bottle on hand for regular maintenance.
By investing a little time and money into a Pressure Washer Pump Saver, I’ve kept my equipment running like new for years. I hope these insights help you protect your investment as well!
