How To Bypass A Pressure Washer

We explain how to set up your pressure washer to go into bypass mode when you are not using the trigger and explain how to do this and why it is important!

[@bobcunningham4223]

What a relief to finally find a video that shows a practical and straightforward way to actually do this. And as a bonus this is the exact unit that I have so that will make it even that much more easier thank you so much.

[@bigshotsuppliescanada9986]

Glad you liked it!

[@autohog]

Excellent video - very helpfull. Thanks for taking the time to make it.

[@bigshotsuppliescanada9986]

You bet!

[@drowization]

Great vid, just what I was looking for, thank you....

[@bigshotsuppliescanada9986]

Your welcome

[@kylemercure2918]

Awesome man thank you so much for the video eh. Most videos only discuss with a buffer tank. I was concerned that I needed a looped system with buffer. Now I know I can plum the vent tube through my truck bed to the ground ad my 4gpm lives in my truck bed with the skid but I don’t have a buffer tank. Right on brotha. Just subscribed. My wife is from Sooke.

[@bigshotsuppliescanada9986]

Great news and glad to help!!

[@jeffunruh4912]

@kylemercure2918 mine is mounted in the truck and I just dump the water on the ground as well.

[@dylanbyrne955]

You're a G thanks!

[@Raniljayakody]

good info.. got all i need..

[@eugenedenny9119]

Thanks Colin

[@sean626262]

Great video

[@451dev]

I have a belt driven Simpson pressure washer 4200psi at 4GPM I did not know it would suck water on its own. that's awesome !

[@bradelias7911]

helpful. do you have kits for the bypass

[@peachypound6108]

Great Vid my friend. So simple, so informative. Question🙋🏽‍♂️: why would you have to cut the tube, when you could’ve just unscrewed it?

[@comeoll]

Very interesting. Thank you for sharing your knowledge. I wanted to ask why my pressure washer doesn't turn off when I release the trigger? Is it a mi-t-m model cm1400 omeh?

[@wernergarcia6820]

Great video , my only question is , if my pressure washer don’t have a bypass , the fitting that screw into the unloader it’s just a fitting with a barb or is it a specific valve

[@jonboysprowash7845]

If you bypass the unloader and discharge water onto the ground will the pump not run out of water? Either from you being on the trigger or off and it running running out? I’m trying to get a new pump where it needs to be.

[@littlespressurewashing]

What a great channel buddy

[@HouseWashingRick]

What up homie, down here in Cookeville giving you the 👋

[@littlespressurewashing]

@@HouseWashingRick much love from middle Tennessee and northern Alabama back at ya 👍 just dropped some new videos trying to help some people on this wash journey “teamwork makes the dreamwork” 🔑 ♥️

[@HouseWashingRick]

Hell Yeah brother, let's grab lunch one day in the future during the winter months and kick it for a little bit

[@littlespressurewashing]

@@HouseWashingRick for sure let’s do it! I’ll be at the HUGE CONVENTION most likely

[@littlespressurewashing]

It’s in Nashville this year in August I believe

[@acihawaii]

Great video and i like the water exiting the hose method Replacing a Simpson AAA EW4040 pump 4 gpm Honda 390 knock off mobile unit Should the new AR pump have an unloader or will an AR pump with a built in regulator be adequate ? Using as a jetter and require short breaks, say 3 minutes to camera drainage pipe Again, like the water exiting the hose method RR

[@OfficialMinecraftMenace]

Thanks for the video! Could you DIY this with a triple AAA pump (4 gallon per minute)?

[@Rabbit.760]

The pump might be rated for 10gpm but that thing ain't pushing a whole 10 gallons thru those tiny jets in one minute, no fkn way

[@noeaguinaga4018]

If your not pulling the trigger the plungers in the pump arent engaging, there's a clutch system in the pump that allows the belt or crank driven to soon freely.

[@donovanstevens903]

Bought this model off someone recently and they removed the bypass tube at some point and capped it off. Would I be able to downstream off of this??

[@tgeorge78]

Can you run a bypass on a built in unloader valve (the one that came with the machine)? The discharge seems to be in the back of the pump with no outlets anywhere near the nob under the unloader. Or would I need to buy an external unloader valve to run bypass?

[@Blake_trammel]

What about on the opposite side of your bypass line it the black nipple do you have to plug that?

[@reginaldhooks1456]

I have a question I tried to bypass mine like that and it lowered my PSI but I'm going to try to bypass it back to my tub

[@keithgehrke3588]

I have a 4000psi 4.2gpm unit and want to add an external unloader do you have what is needed ?

[@zygagne2646]

I have a triple AAA 4gpm water pump on my dewalt… They sell just a plumbing kit with the unloader bypass ( not the whole pump ) I am wanting to make sure I can swap this out. Could you assist if this will work or not?

[@jjgionet1735]

Great video! So I just bought an Echo 4200psi 4GPM with a GX390 and an AR Triplex pump. There are no bypass hoses, but at the base the black unloader pressure knob, there is a brass plug. Is this where I should plumb into? Wish I could send a pic Thanks!

[@bigshotsuppliescanada9986]

It would help to know what type of unloader it is?

[@lifeisrandom23]

Great video. Thanks for sharing. Where do you buy the plugs?

[@bigshotsuppliescanada9986]

We sell them at our online store. They can be tricky to find though and it depends on where you live!

[@axeyplayz1052]

Do all pressure washer have the 1/4 outlet/inlet size ?

[@noeaguinaga4018]

The only time the pump is in need if the trigger being pressed for worry of burning up is if there is any leak in the system. If the machine surges up and down that means there is a leak or your unloader is broken. That's when you worry about cavitation

[@scandyoz3292]

If a pressure washer do have a bypass hose is it Internally bypassing then?

[@g-manm2305]

I have that same unit and I'm fixing to build my skid. What about the thermal relief valve on the other side of the unloader? Since you're bypassing the line does the relief valve need to plugged as well?

[@longlivefreedom9853]

Great video.... maybe i am impatiant.. but it was little long winded in places..... I cam to see how you do this and you got side tracked talking about other things..... My poiunt my guess is that many want something specific...

[@alanphillips1344]

You mentioned about sucking the water with gear driven pumps, some come with thermo relief valves. Would I still do the same thing to bypass?

[@bryanmontgomery4050]

It would definitely be a very good idea, that thermal relief is set just below the limit of the pump as a last resort, a cool pump is always a happy pump.

[@bill_nye_the_russianspy_9642]

I just picked up the same model as yours off a guy for $300, its a 4200 psi 4.0 gpm belt driven, anyway I did the exact thing you did and the water comes out of the hose fast! Then it wants to kill the motor. But when I hook it back up it works perfectly. I don't understand, its the exact same setup as yours and I did it the same exact way as you did.

[@toddfinn5823]

Sounds like your unloader needs adjusted, sounds like someone has cranked it wide open which will do what you explained.

[@mlhm5]

I use a trash can on wheels as my tank. Put the water hose in the trash can, the inlet hose and the by pass hose.

[@juniorgarza8265]

Hey I have a Simpson 3300 but mines doesn’t come with the hose on the water pump, is it possible to bypass that water pump thru the thermal water valve? Cause that’s the only place where leaks does come when it does leak

[@HouseWashingRick]

No

[@TheBryceJohnston]

can you use a direct drive pump for this or does it need to be belt drive

[@peachypound6108]

I believe you can use a direct drive.

[@Louisiana_Frenchies]

Where do you get the plug ? Can’t find them online anywhere or is it just a standard 1/4 inch plug

[@bigshotsuppliescanada9986]

Yes its just a NPT )Nation Pipe Thread) 1/4" plug....No special but they can hard to find. In Canada you can buy them from our online store!

[@jumpman2680]

Do you need this for direct drive pumps too?

[@bigshotsuppliescanada9986]

Yes it works with direct drive. and is recommended!

[@chuckhenderson7266]

how do i bypass a simpson 4000 psi model?? thanks

[@HouseWashingRick]

If a customer comes to talk to you and you have it on bypass how long can you let it run through bypass before you pull the trigger or turn it off

[@Wi_Celt]

It doesn’t matter any more once u have a bypass system

[@TROUBLE8088]

So I'm buying a Preditor 4gpm from Harbor freight can you see if I'm able to do this with that machine? And can I buy the cap u used?

[@platinumhawkpw]

The AR pump that comes with the Predator 420 doesn’t have a bypass hose so no you wouldn’t be to

[@erhelitruck]

Thanks for sharing. Predator 4gpm is similar than your, but doesn't have the hose, it has a cap, so put out and the water comes out continually, I mean water doesn't stop if I press the trigger. is that notmal?

[@Will-tm5bj]

I'm running a bypass on mine now because the guy I was doing his driveway saw water going out of my ballvalve while I walked away to get something. It ran for maybe 45 50 seconds 😮😮😮. Still running fine but I don't want that again

[@davidstearswindowcleaningr2677]

What brand OF pressure washer? Name brand

[@berniewhitehouse2105]

Is the bypass hose size for a 5gpm 3/8”?

[@Victor-nn2wi]

Yes and the plunge that you would use would be 1/4

[@tgeorge78]

I’m confused because my 4 gpm machine came with no such hose.

[@taborprowashllc6391]

Hey, if I’m off the trigger and pump is cycling will it draw chem from my bleach tank?

[@overlandjunky5535]

That's a great question. I'm assuming it will as well. That's a conundrum we're in.

[@overlandjunky5535]

Remedy: you could add a 3 way ball valve to the water relief hose so that when you use the bleach, it cycles and will not be wasted onto the ground. And when you just washing and rinsing, turn the ball valve off so that it can relief all that water onto the ground. This is what I would do.

[@Nicholas1999]

The only way this wouldn't work if you use high pressure soap. It will just go on the ground or in your water tank

[@bradsnyder978]

Don't understand. If you bypass and string it to the handle,when you got to move it, isn't water running right at the tech

[@bryanmontgomery4050]

Note, the unloader only slips out a small amount of low pressure water, just enough to keep the pump cool.

[@mainabauza58]

Do you all actually watch over your videos?

What's your number again bro.? Dallas Texas here
