Replacement Pressure Washer Pumps Review

If need replacement pressure washer pumps, use my expert tips &  independent pump review to get the job done quickly. I share my pro tips to help you get the job done right.

And I wanted to share my #1 top recommended replacement pressure washer pump: the Generac universal pump that works with all pressure washer brands & is on Amazon.

Before you shop for a replacement pressure washer pump, follow my easy, but critical, check-list to make sure you get the right pump:

1. First, check to confirm that your existing pump is either an axial cam or triplex pump.

2. Take a look at your broken pump to see if it's mounted horizontally or vertically. Here's my tip:  if your pump is mounted next to the engine, it’s considered a horizontal mount. If your pump is mounted underneath  the engine, it’s vertically mounted.

3. You need to confirm the PSI (Pounds per Square Inch) and GPM (Gallons per Minute) ratings of your existing  pump. Your replacement pressure washer pump PSI & GPM ratings must match the rating of your original pump.

4. Lastly, count the number of bolts & the bolt pattern of your existing pump. You need to match the bolt pattern to your new replacement pressure washer pump pattern.

    Maintenance Tips for Replacement Pressure Washer Pumps

    With improvements in design & technology, pressure washer pumps now can run longer with less maintenance.

    To keep your pump running, you need to always make sure you keep dirt out of your pump - and that you change your pump oil on schedule.  The only exception to changing your pump oil is if you've got one of the newer style sealed & maintenance free pumps on the market.

    You should change your pump oil every 50 hours of running time - or once a year - whichever comes first. Your owners manual will tell you which oil brand to use on your washer.

    To change your oil on your pressure washer pump, you'll first need to drain the oil and fuel from the engine. Then remove the oil cap from the pump and drain the used oil. You'll need to tilt your washer to drain the oil.

    Now fill the pump with fresh oil. Put your oil cap on again & make sure your washer is in the upright position before you start it up again.

    I hope my pressure washer pump replacement tips help you get your unit up & running again!
