Excellent presentation. I learned a lot from your video. My Honda GX390 3600 psi was building pressure @ 3200 psi. As soon as I press the trigger the pressure immediately dropped to 2000 psi. Now I know what to do to fix it. Thanks to your very informative video 👍🏽
Hi Brian on my AR 1500 psi electric pressure washer. It wasn’t building up pressure so per.one of videos I pulled the 6 plugs to check the check valves 4 of them only the plastic cap, spring and the cone shape came out. two of them the whole things came out. So how do I get the rest of them out. Don’t know if I explain myself good enough to you. And help would be a great help. Thank you
I get this request pretty often. I have said I will make a video when it happens again. It doesn't happen that frequently to me. So it has been hard to get that video made.
Great vid about this style unloader. I have an Annovi Reverberi Model XRV4G.32 that is not building pressure. When I tried to remove the unloader, both of those hollow bolts twisted off. Now I have to try to get out the broken bolts. I am not even sure I can buy an unloader for this. I found a CAT 7860 that looks similar, just not sure if the bolts are the correct size though. Any tips on how to get out these hollow bolts? I'm going to start beating on them with a hammer and chisel tomorrow and see if they will come out. Hesitant about using heat because of the cast aluminum housing. Thanks.
@@Brian_the_repair_guy Haven't got a chance to get back on it, but will give that a shot. I did find a set of just the bolts for my unloader for about $20.
Sooo now some confusion @11:55 when you're talkin about sitting the pressure are you talkin about the head pressure? or operation pressure? Example with a pressure gauge attached to my outlet at the head when I let go of the trigger my idle head pressure goes to and settles just below 4,200 PSI but when in operation when I have the trigger pulled pressure drops down to just above my machines rated pressure which is 3800 PSI.
As I stated in that section, periodically pull the trigger as you make adjustments and check your gauge. Sorry if I wasn't clear. This means check the pressure on the gauge at a "no flow" state. So the pressure you see will be a pressure at idle speed with no trigger pull.
Hi I have a Annovi Reverberi electric 1500 psi. The top mounting bolt on the unloaded broke off when I went to use it. I will replace it but is the pressure setting the same as like you were doing on the gas pressure washer. Will the electric motor bog down when too much pressure.
I noticed there's a plug on the otherside of the high pressure outlet. Can i connect a bypass line to that plug section? Just making sure on this type of unloader style. Thanks
@Brian_the_repair_guy Wait, I'm talking about the unloader valve unit itself. I thought the bypass gets installed on the unloader only? I don't install a bypass on the side where the thermo valve is located, correct? Sorry this is a different style unloader. I just want to make sure. That would be a great video. "How to install a bypass on these side bolt unloaders" Strange they didn't install a bypass on a belt drive pressure washer. Especially when they can pull water from a buffer tank and the bypass line goes back to the tank. Thanks
Depends. The injector is based on an increase of water flow and reduced pressure. If the unloader is restricted, it could cause the injector to not work
@@washwav I have not had one break in a long time. Hard to make that video without one broken. Message me in my Facebook page, I may be able to help better there
Washer still has decent pressure. the original injector started to backwash in bucket I put 2 new injectors on still no suction checked all hoses and gun no leaks. Pumps not leaking. So thought it could be my unloader . I’m close to fixing it with a 10 pound sledge hammer lol
Brian, Great stuff. I have a pressure washer with a similar pump. When I am pulling on rope to start the washer, if it doesn’t start within one pull, it gets hard to pull unless I press the wand trigger to release water pressure. Once that is done, I can pull it again. What are your thoughts on what is going on? Thanks.
This is normal. When you pull, the pump begins to build pressure. The pressure is enough to male it difficult to pull again. You can hold the trigger down as you pull, or you can get an ez start valve and install that.
@@Brian_the_repair_guy Thanks. Was wondering if it could be normal but didn’t recall my other pressure washer doing that. Maybe it has the ez start valve. I’ll keep watching. Like your videos.
Cheers Brian, I bought a new gas pressure unit. I am about to use it. I have been warned a few times on here not to start the motor without running water through it first. However, my water source is a tank where the unit draws the water from. So, I need to start the unit dry then the unit sucks the water in. But this method seems to go against warnings online here?
@@Brian_the_repair_guy You connect one end of the hose (supplied) to the inlet and put the other end into the tank. The unit syphons to the inlet automatically when the motor is started up. On the other hand, you can connect the inlet to a garden hose with tap water.
@@eamonnmurphy5385 my suggestion is attach the hose to the tank via a valve at the lower end of the tank. This was the head pressure of the water will automatically supply water at start up and the pump will be used to provide pressurized water and not do double duty by siphoning as well
@@Brian_the_repair_guy cheers, good suggestion, however its an underground tank; also, keep in mind that you need a minimum 20psi and 5 gallons a minute from a water source for this unit. If you draw from an open tank, the unit sucks the water it needs so you don't have to worry about high volume of water or enough pressure in a hose ect.
@@eamonnmurphy5385 you hadn't mentioned the underground tank. As far as the requirements for your pump, those would easily be met by the set up I mentioned. In fact, they would exceed the specs you will get by syphon set up. I have never been a fan of the syphon set up. The pump does double duty, which causes more wear. If you have an underground tank, I would suggest adding a transfer pump to a 20 gallon container to hold the water and attach the washer to the bottom of the 20 gallon tank as I mentioned earlier to eliminate the syphon aspect.

I hope this video helps. I have a couple others on loss of pressure as well. Be sure to watch those
Very nicely done. It's the most important part on the machine and the most misunderstood and you explained it perfectly. Thanks
Thank you

To get them out you just have to work them out with a pick or small flat head. If they have come a part you will need new ones
Would like to see the video when the bottom on loader Bolt get rusty and broke in it how to get it out cuz it happened to my power washer

It will bog down, but it will quickly trip the breaker
@@Brian_the_repair_guy thank you for your expert opinion. I enjoy watching your videos. Thanks again Dave.

Just making sure on this type of unloader style.
Thanks
The head is a mirror image of the left and right side. You can place the bypass set up on either side

@@michaelc7283 take a look at this video, this may be what you are looking for.
@Brian_the_repair_guy
Brain,
I found your videos on how to change the bolt unloader to the external unloader.
The video was perfect and dummy proof 🤣👍
@@michaelc7283 glad to help
Will a soap injector still work if your unloader is going bad
Depends. The injector is based on an increase of water flow and reduced pressure. If the unloader is restricted, it could cause the injector to not work
Did you make a video about the unloader bolt breaking inside the pump
That’s the only part I need but you said “I won’t make that video until it happens “
@@washwav I have not had one break in a long time. Hard to make that video without one broken. Message me in my Facebook page, I may be able to help better there

I believe I have a video specifically on the injector and how to determine what the problem my be. Take a look at my library on injectors.
Try this video. If it does not help, let me know. ua-cam.com/video/ESLjvl2l5p8/v-deo.html
@@Brian_the_repair_guy thank you
2:50 what is the purpose for that part? is it to release pressure for easy start? Thanks
That prevents the pressure in the hose ( when the trigger is released or when the machine is turned off under pressure) from backflowing into the pump
Do u have a video of checking pressure with gauge ?
I will put a video together this week
Look forward to that . Thank you
On these bolt style unloaders can you run a bypass to a tank?
Yes you can, but it takes special plumbing

Is that 3/8 or 1/2 unloader
This is a 3/8 setup
