Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use ruclips.net/user/postUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP . And very nice, too. I'm surprised at the power-it's more than we'll ever need, and we've not even used the most powerful setting yet.I've cleaned off a dirty concrete porch to get it ready for sealing, started to clean siding, and I know this pressure washer will be terrific for cleaning tools this fall.The only issue we had is we had turned around the hose connector, and it leaked. Once it was on correctly, though, we had no problems with the connection. Just remember that the end with the green knob goes towards the hose. It's obvious now what we did wrong, but not necessarily obvious at the time.
So, my pressure washer was doing this , the same thing. I thought it was dirt. So I checked all the simple solutions. But nothing. So I came across your video. And sure enough it was the o ring. Thanks man. You save me $150 Service fee. You the man. I will invest that $150 into the Business.
😅😅😅
#1 thank you so much for taking the time to make your videos. I’m looking to start a business and it’s been immeasurably valuable.
#2 I just got a new Landa that has an unloaded on it. Do you think you could do a short video on that? There are videos out there on them but you’re always a lot more clear and insightful.
I have TroyBilt GSV190 Pressure washer. Year ago used it, now, engine runs BUT NO PRESSURE and water dies not come out at all.
I am not a handyman, but, willing to learn and be DIY! Thank you
Absolutely best advice anybody has ever given on RUclips why the people that are new in the business needs always have an extra set of O-rings and check valves I agree the and extra unloader wouldn't hurt neither Golden Nugget brother keep up the good work wash own
+Road Dogs Dirt Relief we’ve been caught so many times without the needed back up parts and it is so frustrating! Thanks for watching, appreciate you
The best information was when you pointed out that you should look down into the cavity and check for a destroyed O ring. Great advice!
very helpful thanks for sharing your knoweledge
Glad it was helpful!
Great Video! that was really good video especially for new guys getting into the business!!! Thanks Mike
Thanks Ryan.
@@AllAboutPressureWashing Where can i buy the check valves ? Or the O rings ? How do i know which ones i need ?
Always, so much good information. Thanks!
Our pleasure!
Thanks for the information
My brand new pressure washer was surging do to the chemical injector being installed at the factory backwards. Ball was under the spring
+jmal88 dang! We all have days like that, even the folks at the Manufacturing facility that made your pressure washer. Had to be frustrating
Thankyou for sharing. For a new guy in the business this info is super important especially if I’m out in the field. Much appreciated sir.

Very helpful.
Experiencing something similar with my pressure washer.
Awesome, thank you for putting this together! Exactly what I needed, my Simpson pressure washer was doing this same thing and this being my first one I’ve owned I wasn’t sure if the pump was failing. Simple check valve clearance and o-ring replacement was it. Thank you!
Always good to be able to work on your equipment. Quick fix, back in action. Good video!
Amen!
Thank u, man. I replaced the Downloader valve, and the problem is still I will get de kit replacement, and I will do this 👌
Here one for you. A friend of mine runs Hawk pumps, XLT2230 & number of XLT2730 all rated at 4350 psi for drain cleaning - never operated with a pressure gun or valve - its all remote start with so there should never be any spike pressure. The pumps have been purchased years apart so will be from different production batches. On the XLT2230 he has blown the cap/plugs on the 'Low pressure intake side' & on the XLT2730 this has happened 6 times - its just one plug that blows out at a time, not necessarily in the same location. The thread is nearly ripped flat & on 4 of the plugs the sides are ripped open like paper.
The pumps are fed by a large water tank, with low water cut out, 32mm (1-1/4") feed hose & the tank has never been down low when this has occurred. f he runs a threading tool back through the head where the cap blew out of & then installs a new plug the pump carries on running as nothing had happened.
Do you or anyone have an idea how the intake side plugs can blow out like this instead of the high pressure side, especially given there is a 32mm feed hose plumbed into the low pressure side so you would expect any back pressure to just go back up the feed hose to the tank.
The supplier claims they have never seen this, almost as if they don't believe it & they but can't provide any thoughts on how this can occur. It happened again this weekend & I suspect whatever is going on is repeatedly happening, wearing down the plugs threads over time & eventually it blows.
I would love to hear anyone out there's thoughts.
My symptoms are identical. Can't wait to get home to try it out. Thanks for sharing!
+John Muller glad it helped - let us know what you find!
thanks, there needs to be more commercial pressure washer videos out here lol
My 22 yr old Water Wacker, Honda 6.5 hp has the exact same symptoms. I will pull it apart this afternoon. Cheers, your Chauffuer J Bruce, Hollywood North 🇨🇦
Thank you, you saved me a headache at some point
+Jeremy Olson glad we could help - have a great day!
Thank ya sir ! This was a big help got my guys back working thanks to you !
Someday I'll find you and I'll give you a hug 😅😅😅😅 You just saved me from some horrible pain. 😁
good vid thanks
Thanks
i have one that collapses the input water hose 3/4" Acts like a vemt is clogged, this unit sat for 15 years , my sister asked for help i cleaned out all the varnish and honda engine runs as is should GX200 like mine, however doesn't make a lot of pressure and if i do not depress the wand trigger the unit will stall. took head off and cleaned everything , but something amiss
Probably bad seals
nice tutorial
Thank you! Cheers!
Hey Man, good job boss!
Hey, thanks!
So you use the German torque method, Gutten tight? I love it
Exactly
My washer was running on half pressure,took off a bolt with a ball bearing and spring,inside.a piece of metal was stopping the bearing from running smoothly.put the whole lot back in and perfect now.
That would be the chemical injector - not the pump.
good explanation thank u
Good info... I just experienced the cavitation on my rig
Big Mike! Thank you for this video!! It saved the day for one of my workers!!
The Big Mike Termun!
Thanks for the help . My machine won't work on the soap nozzles. Any advice?
+Jr Mccoy can’t tell
Much without knowing more but I don’t really diagnose over RUclips. Talk to the folks that you bought it from, they will know way more than me
Informative video, this sounds like the exact problem I'm having so ill have to check it out!
Thank you.
+Mike Carmody 👊🏻
On my pressure washer, the snap ring that holds the pulley in snapped, and the pump was making weired noises when I let off the trigger, and the flow was way reduced.
+Adam Chicoski good info and something to look for, thank you Adam.
Hey Mike, this video is a game changer. Also just signed up for the Inner Circle the other night. Thanks for all sharing all the fantastic content. Just to be clear, I mean No BullS$%t information, You are straight to the point. - Luke - Owner - Port Imperial Power Washing
very well done. thanks for posting this
Great video! Thank you!
You should always blow & suck on the check valves when testing them. If you can suck air through them they are not seating down fully. And as a pro tip never use an impact to tighten bolts even just loosely. If you tighten them down too fast the check valves can get crooked in there and ruin them as you tighten them check valve caps down.
+Jordyn Martinez exactly what I did, good tips. The impact is fine as long as you know how to use it, time is money and that speeds up the process. Thanks for watching
@@AllAboutPressureWashing yeah I’m just thinking of other people putting it on and giving it too many Ugga Duggas with an impact. I’ve always used my 1/2” 22in ratchet to be safe.
Another great video! Thank you 🙏
Hi I have the same problem I check the check valves and it has all it o rings, and it still vibrate while in idle
Great video you just save me couple hundred bucks
Glad I could help
Mine is trowing water mixed with oil trough the gun
Man this was fantastic!
👊🏻
I got the jump, but it’s also making a bang noise. When it rains it pours. Almost done with a job, and 3 more lined up.
+Veritas Designs bang noise doesn't sound good - could be a rod
@@AllAboutPressureWashing my lines are pulsating but there’s a bang noise. Running an RB600 (STIHL) when it rains it pours. Because as soon as I think I am getting ahead I have this happen. Funny thing is just upgraded my gun with a slightly longer barrel then what it came with. Wash broom, and a telescopic pole for gutters and two story homes. It’s my first power washer. Second season of power washing. Sucks because I am in the middle of a job, and three more lined up for next week.
@@AllAboutPressureWashing I could leave my cell. If you want me send ya a movie
@@AllAboutPressureWashing leaving voicemail at your site.
+Veritas Designs contact the People that make it or where you bought it. I'm
Not going to be able to help you with it.
Good work man
+Facundo Rutherford 👊🏻👍🏻
Thanks mikev
see you tight the bolt so how many ft pound ?
I would consult the manufacturer of yout pump - - the General Pump TS series requires 22.1 foot pounds of torque on these manifold bolts
Nice
Thank you!!
I needed this!
No worries
Your the man
Thx
Im using 5/16 high pressure hose for my 4400psi 4gpm machine and im so frustrated about vibration of hoses. I replaced my cart, even replaced my old AAA pump that went broke and with the new Comet 4000psi 4gpm pump and skid mounted on truck my hoses are vibrating as fck. Already checked the check valves and orings like u said on video, they are fine. Do you think switching to 3/8 hose will help? Do you have any vibration problems with 3/8 and 8gpm 3600 psi? I might be switching to 8gpm near future and i dont want this vibration any more.
I have pump oil that flows out of my red cap hole when pump warms up and also loose pressure.any ideas
What is the problem when I turn on my pressure washer, pressure is being released from the valves on the pump. Water is being sprayed from the pressure valve with pressure?
Bad o ring - not sure what exactly you are asking
Great content, real confidence booster. No Teflon tape?
+Chris Jelley thanks - Teflon yes
I'm going to have to check mine, I have the same pump in its giving me the same problems. My unloader is set up the same way, do you recommend switching it so it is easier to replace if needed? And if so, What would you switch it to?
great info
+Fidelity Pressure Washing thank you! Where are you located?
My pressure washer drops from 4200Psi to 1000psi. When I pull trigger. What can it be?
+Sergio Batres the unloader could be bad
Have a question can it cause your hose to blow off if you're not getting good pressure because my hose blue off a little while ago which I was not getting good pressure and my host started vibrating real bad and the next thing I knew the hose blew off off of the pressure washer itself thank you
Great video 😄
+Simply Clean Pressure Washing & Window Cleaning thank you!
My name is Fred and I'm watching your video and I have the same uploader that he has that you helped them can you explain to me how that uploader works because I'm having a problem with that
What size o rings did were they? Thank you awesome video
Depends on the pump
I love you for this video pretty positive you saved my ass
Hello! Great informative video. I have an AAA pump. 4400psi.
It has little plastic plugs on top. One of them is spewing water out. There isn't a loss of pressure, just that leaking problem. Can you please give me a what to do direction for that?
Again, thanks.
YOU need to buy a new pump.
Rubber hammer rather than a breaker bar some times works. Instant torque. Doesn’t twist the whole pump.
Hit on the shifter instead of pull it to crack it.
I recently upgraded to a 21 litre per minute machine and I was using it today and it was jumping and sounding very weird. It would start out with super high pressure like normal for about 5 seconds then start to go shit. I thought maybe it could be because I was using a low pressure rain water tap?
How do you remove an air lock in this kind of pump
Shouldn't you have carefully removed the old blue Loctite from the thread, and re-applied new before tightening down?
+barlow2976 you can - I don’t
@@AllAboutPressureWashing Tempting not to bother, but as the manufacturer says do it, I'll do it.
What size o ring on ez4040g?
Why would you ask this instead of just google it or call someone who sells them or who you bought it from
Can I ask if these check valves are universal? Have a Cat pump that looks the same as yours...same socket dimensions at least...but can't find a replacement specific to the model we have.
No.
My pressure washer engine running than press idle the engine stop ?
Anyone who claims they don't like pressure washing has clearly never held that pulsating, high-pressure hose between their legs--you know, for better leverage. 😃
Can running it pulsating cause the pump to tear even further?
Yes
@@AllAboutPressureWashing ok. Thanks for the response.
Put a little bit of grease so you wont scratch the o’ring😮😮😮
...ur rite...u don't have to b some1 with some sort of high education to fix something.....just a tad of common sense....👍
