How a pressure washer unloader valve works (with cut-away view)

This video shows the unloader valve in a cut away of a 2700 psi Homelite Pressure Washer. After watching this video you may be able to get your pressure washer to build pressure again.
Please note: I am not a mechanic and I do not work on these things for a living. I’ve only worked on one pressure washer in my life and this video is the result of that. After watching this video you should know more or the same about pressure washers as me. So I’ll apologize in advance if I don’t know the answer to any questions.

7 years later you're still helping people with this video. Thank you

Wish more ppl would make their videos like this. No long intro graphics, no bs small talk, just straight to the point

Your pump sacrifice was not completely in vain. The cutaway visual helped me tremendously diagnose my own issues. Thanks for the video!

5 years later and your knowledge is still saving the day and only took me 7-8 videos of people who, I don’t know or can’t say what their talking about but if I listened to half of them I would have purchased an entire new pump but thought, DAM I only have 2 hours on this $375 rig and it just can’t be the pump but then I found your video and BINGO!!!
Such an easy fix and will now know it until my dying day!!!!
God bless you brother 🙏🙏🙏

As was stated, love the detail and directness of the video. Thanks for helping me understand the functionality of this valve.

I have a Homelite 2200psi gas pressure washer that stopped working. There were no leaks in the pump but there was very low pressure. I took the pump apart and unstuck the little piston with a few taps from a screwdriver handle just like this video says. Put it back together and it now works perfect with full pressure. Thanks, you saved me the price of a new pump!

Very helpful. This video should be studied on how to make a DIY video. No long intro. No annoying graphics. The cut away pump was so helpful. You sir rock. Ty

You are now the Most Hated person on the list of repair shops... great video! God Bless!

Awesome! I wish I saw this a week ago, but better late than never. This needs to be number one in search results for power washer trouble shooting. Search result say to check this valve, but nowhere to explain how or why. All units seem to have this same assembly, a little attention here saves money and time! With this, you can buy rejects in yard sales and get em going to resell for $$$. Thank you Mr Morgan!

Thank you Sir. All I had to do was tighten that valve!? Repair shop wanted $150 to diagnose my issue of low pressure. Saved my life!!!

This is exactly what I'm looking for in a YouTube "How To" video.

Guy saved me 70 bucks. Great video. Real easy to do once you know what to do. Thank you

Hey Corey! Thanks very much for taking the time to put this video out there for the rest of us. The cutaway pump was outstanding and the total disassembly of the uploader is exactly what's missing from every other video I watched on this problem. Thanks again and take good care.

Thank you sir. The Internet can seem like such a crappy place and then you search and find something like this video that explains my problem clearly and simply and allows me to fix something. Bravo.

Excellent video. Never saw a cut away not produced by a company to show their products. Thanks for the time you devoted.

Here is some knowledge. The device you're displaying is an integrated unloader, with dual-bypass. The small bypass is used to unload the pump until a certain pressure is reached. This makes it easier to start the pump/engine assembly. The large bypass is used to unload the pump when a certain pressure is reached. This stops run-away pressure and dramatically reduces wear on the pump seals, when not spraying. However,  if left in this state for any length of time,  temperature and wear increase. Always stop the pump if you're not spraying for more than a minute or two. Also, the unloader is not to be used as variable pressure adjustment. That's what different orifice-size tips are for.

Thank you for the informative video. You saved me about $100.00. I was thinking about buying a new pump, but I fixed mine after watching your video. Much appreciated!!

[jim]

Nice video. You are the only one who shows the second inside piston!!!! I checked my unloader but didn’t check that! Hopefully you will save me from buying a new pump!!

Thanks for posting this video. It got me up and going.
One other thing to mention, check the inlet water screen. Mine was completely clogged, so therefore it may have been part of my problem by not
Letting enough water pressure into the pump...thanks again. Rob in SC

Thank you! I had no idea why my pump failed before I saw your video. You Saved me $$$
