Watch how to adjust a pressure washer unloader with Larry Hinckley, Sr. for PowerWash.com. Larry explains and demonstrates the proper way to adjust a pressure trapping unloader.
Need an Unloader: www.powerwash.com/pumps-and-re...
Find a pressure gauge: www.powerwash.com/parts-and-ac...
You should always know the GPM and pressure (PSI) that your machine is designed to run prior to doing any work on it. Use a Nozzle Selection Chart to determine the best nozzle for your purposes or contact a pressure washer repair facility for that information. Read a Nozzle Chart: www.powerwash.com/nozzle-chart
After installing a new pressure trapping unloader, you will need to adjust the unloading pressure. The first step of the unloader adjustment process is to install a pressure gauge at the pump before the unloader for greater accuracy.
Once the gauge is installed, start the engine without a nozzle on the gun and establish a flow of water through the system in order to flush any foreign materials from the lines. Next, install a new fan spray tip that is properly sized to give you the desired pressure for the gallons per minute that your pressure washer is designed to run. Squeeze the trigger on the gun and monitor the pressure reading on the gauge.
The object of this process is to adjust the unloader until the gauge indicates the pressure that your machine is designed to run while the trigger is depressed. When you release the trigger, the needle on the gauge should momentarily raise to a maximum of 300-500 psi above your operating pressure. As you are adjusting the pressure, if the gauge's needle stops rising before the machine reaches the desired pressure, stop the adjusting process and determine why.

@metroporter5211 10 лет назад

A couple quick questions for you Mr. Hinckley: Back-story: In an effort to get away from an aluminum manifold pump, I just purchased a (brass) slightly more powerful pump than OEM. The EBHP rating on the old pump was 3.6. The new one is 4.3. My questions are: 1) Is a 5.5hp gas engine adequate power for this newer pump? 2) If not, may I use the unloader valve to effectively reduce the operating load? 3) Where might I find one of those gauge assemblies you use in this video? Thank you!

@dekonfrost7 6 лет назад

Thanks.

@Powerwash 10 лет назад

The pressure gauge is installed before the unloader or on the head of the pump to get an accurate spike reading. Check the description area for a link to where to buy a the pressure gauge used in the video.

@451dev 2 года назад

should you adjust the speed on the engine to the pressure you change on the pump ???

hello i have a 3100psi subaru and i get a strong kick and hard to press the trigger also engine dies and backfires loud most of the time? i took out the unloaded valve and the pin moves freely and i took it apart and all looks clean. Maybe its just turn clockwise to much ? i did notice theres a white little plastic oring and it was a hairline crack in the unloadr valve assembley would that affect anything ?

@danielleredfearn8233 10 лет назад

I have a upright heated 1500 psi pressure washer with a TT9061 General Pump. I bought a new unloader and was told to set it by the pressure gauge. Can you tell me where and how to install the pressure gauge, it didn't come with one on it when I bought it.

@Ben-sv9op 2 года назад

So if my Pressure washer is 3000 psi. When I’m holding on the trigger gauge should be 3000 psi and when I let go it should be like 3300?

@edesir Год назад

With that being said, I guess the tip size doesn’t matter.

@newwavepressure6478 Год назад

@eddiddy hope ur right I don't hav a 6.0tip my pump it 5.5

@Brad.W Год назад

@@edesir what he failed to mention is it should be 3000 psi with the 0° red tip if you do not use the 0° red tip like myself who rarely goes narrower than the 15° yellow tip you need to adjust your machines unloader accordingly. Key thing to pay attention to is do not let it go above 400 PSI above the rated pressure of your machine when you are not depressing the trigger on the gun. IE: when you let go of the the trigger on the gun and your machine is rated for 3400 PSI the standby pressure should not be any greater than 3800 PSI. Hopefully this makes sense to you. In this video he was using the green 25° tip which is why the pressure was too low for him but it probably is where it should be if he puts the 0° red tip on the wand. Manufacturers warranties will be voided though if you blow your pump and tell them you adjusting the pressure for the next nozzle down from the red-nosed or because you don't use it they will void the warranty is supposed to be adjusted for the red 0° tip only.

@edesir Год назад

@@Brad.W Great tip!! ( no pun intended ) :) I never used the red tip and adjusted mines w the green tip. So if i were now to use a red tip, i could potentially blow a seal.

@Brad.W Год назад

@@edesir to be fair that's how I knew because I just for the orange tip on some random day I needed to use the red 0° needless to say it was a bad idea the pump seal within the first hour on a triplex pump from the too much back pressure.

@johnherrera2132 4 года назад

Can a 4000 psi hose cause damage to a 4400 psi pressure washer? Or is it possible to adjust the pressure from the unloader to accommodate for the hose? Thanks

@Shanzo04 3 года назад

No! It'll be the other way around. If your pressure washers psi was set higher thn your hoses max psi rate it will burst your hose so its best to keep the psi on your pressure washer lower than the max rate on hose

@bradlaney2922 Год назад

Does the nozzle and hose length effect the psi reading when adjusting the unloader? I have a 5.5 gpm at 2500 psi and 200 ft of hose, so if nozzles do effect it, which nozzle should I use to test and set the unloader?

@Powerwash Год назад

Use the nozzle that is rated for the machine. Install the pressure gauge as close to the pump as possible. Now you set the unloader

@bradlaney2922 Год назад

@@Powerwash white, green, red nozzle? I guess I don’t understand what that means

@Powerwash 11 лет назад

The pressure gauge should be sized to accommodate the pressure rating for you particular machine. For example, if you have a machine that does 3,000 PSI get a gauge the is rated for a higher PSI - 4,000 to 5,000.

@R3belD0gg 3 года назад

I just bought a DeWalt 3600 PSI machine recently. I turned the pressure down at the unloader to wash my car. How difficult should it be to turn that thing? I was afraid I was going to break the plastic handle. Also, it's so tight I had to undo the hose because otherwise I can't get my hand around it to grip tight enough. I tried leaving the hose on and turning the pressure back up to do my rims and was rewarded with a nice burn on my forearm where I touched the exhaust accidentally, trying to get an angle on the thing. It's not vertical like yours, or like in the DeWalt manual, but sticks out the side and is between the hose inlet and the frame. Really poor positioning. Should it be that hard to turn? Just use pliers next time?

@Powerwash 3 года назад

It's best not to adjust the pressure by changing the unloader setting. Here is another video I made that explains this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3mGkOE6awms.html

Does it matter which spray tip you should use while setting it?

@Powerwash 7 месяцев назад

Great question! It depends on the GMP and PSI of your machine, you will want to use the tip that is right for your machine. Feel free to call us at 1(800)-433-2113 or go to powerwash.com/nozzle-size-calculator/

@quoctrangchuotbeo4 4 года назад

Thanks. Maybe preowner got wrong size for red and white tips

@dontblameme6328 4 года назад

Good video but I think you need to take into account there is pressure loss at that gauge. Meaning that the pressure can be 500psi+ at the head HIGHER than the pressure at the outlet. Running the risk of over running the head pressure is damaging to say the least.

@Powerwash 4 года назад

Great comment. Yes, the the closer to the head of the pump the better for checking pressure. I will say in my 40 years of working on equipment that I have not seen a drop of 500 PSI going thru the unloader. I have however seen a drop of 500 PSI after going thru the coils on a hot water machine follow by 200 - 300 feet of pressure hose. That is not uncommon.

@buildstoys 3 года назад

@@Powerwash Given the loss going through the hot water coils, how should you set the unloader (still set the pressure before the coils)?

@Powerwash 3 года назад

@@buildstoys Yes, always measure and set the pressure as close as possible to the head of the pump.

@buildstoys 3 года назад

@@Powerwash Thanks for the reply. So do you set pressure with the coil removed from testing (and then when everything is back inline, your wand pressure could be a few hundred PSI lower going through coil/hose)?

@Powerwash 3 года назад

@@buildstoys The easiest thing is to mount the pressure gauge at the head of the pump. That way you always know what the pressure is at the pump.

Hi, I have a 4200 psi rated BE commercial pressure washer, has a Honda gx390 and 67dx39g1l cat pump. I recently bought a pressure gauge to measure psi from the pump. I attached after the unloader and got readings of 4200 psi at operating pressure(wand trigger squeezed) and 4600 psi bypass pressure(wand trigger released). Is this normal readings or do I have to adjust the pressure down. How to I adjust the pressure to be in accordance with my 4200 psi rated machine.

Hello Larry Hinckley, Sr.. We watched your video at: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-aWcdl3f1gaw.html . Do you have any experience with resolving overheating in CAT pressure washer pumps? We own a CAT Pump Model 2SFX30GS. It has developed an overheating problem. It overheats after 3 mins run time. Our Pump Tech replaced Valves, Valve seats, Seals, Bearings and Unloader. Can you offer some advice as to why overheating still occurs? The original overheating event melted the Oil Fill Red Cap. We're not certain but the overheating seems to be occurring in the crankcase. Thank you.
