great video, I use a honda Gnx 390 engine to a AAA pump rated at 4200psi and 3.5gpm. it does have the unloader built into the pump head unfortunately as i was not a smart shopper at the time and did not know the difference. rather than selling the unit i was looking into options to improve the longevity of it by adding a better offloader system like yours.. Do you think i would be smarter to just start over with a better pressure washer system all together or is this work to correct the offloader design worth it. cheers!
@DirtyDriveAwayАй бұрын
@richardnichols2064 the GX390 motor is a good engine. Although the pump it's coupled with is all pressure and no water flow which is not the best way for cleaning performance. You can have all the pressure you want but unless you have decent water flow it will make cleaning hard. Is that pump gearbox? Personally I wohld junk the pump and fit something like a Interpump WS202 with an RS500 gearbox. You can then fit a K1 unloader like my video and it will transform your washer and cleaning experience. The WS202 is less pressure at 3000psi but it will give you 5.5gpm. I mean everything has a price point but you already have the engine. Upgrading the pump/gearbox will be the best option. 👍

@JaspreetSidhu13 ай бұрын
@@DirtyDriveAway So, I'm cross the pond and upon further investigation, it looks as if the outlet port on the pump head is 3/8 BSPP (British Standard Parallel Pipe) for which I can find an adapter for here in America, but as a follow up, can you share the specific type of hydraulic fitting style (e.g. 3/8 BSPP male to 3/8" Female JIC) or share a link to the particular swivel adapter you're using. Also, thank you for the quick response.
@DirtyDriveAway3 ай бұрын
@JaspreetSidhu1 the swivel fitting will be a 3/8"bspp male to 3/8"bsp female. On the pump head itself it would be a female, so you can fit a 3/8"bspp equal nipple to convert it to a male. You then screw the swivel into the unloader and then the female attaches to the male nipple on the pump. Alternatively you can do it the other way around and have the equal nipple in the unloader and thr swivel in the pump head. Doesn't matter which way around you choose. America tends to use NPT threads which are similar to bsp but the thread pitch is different and therefore not interchangeable. I don't see JIC fittings on pressure washers.

How can a seal the unloader with a metal ball and plunger?thanks
@DirtyDriveAway28 күн бұрын
@dantec8854 if it uses a ball bearing and a spring, you could remove the spring and fit something solid inside, like a bolt, if possible. Some unloaders are different, and not all will be as easy to convert. All you need to do is figure a way to stop the plunger from moving.
@dantec885428 күн бұрын
@DirtyDriveAway so by removing the spring and adding the bolt the plunger will constantly pressed down on the ball to not build pressure right?
@DirtyDriveAway28 күн бұрын
@dantec8854 yes, this will stop your internal unloader going into bypass. This will block off the bypass port when pressure is built up when releasing the trigger. The newly fitted external unloader will take over the bypass operation.

Great video, my question to you is if I put the new bypass unloader Ar model VRT-310 in front of the AR model RSV4G44 pump without doing what you showed us. Will it work ok if the original set to max pressure and new bypass one set lower? Or should I just bite the bullet and take the parts out.
@DirtyDriveAway6 ай бұрын
In honesty, I don't think the new external unloader will work properly. Even if set to max pressure on the pump, the internal unloader may still want to bypass. The two unloaders will then counteract each other. I mean, it may work, but there could be a chance that the max setting on the unloader is the max the pump will run at, therefore the pump unloader will take priority. By blocking off the pump unloader, you effectively ensure that the external one works all the time. I've been running mine like the video all season, and it works great. You could try your way before committing and test it, although I fear you may end up with issues down the line.

@DirtyDriveAway6 ай бұрын
@mikef124 easy start isn't really needed with a flow sensitive unloader as there is no pressure in the hose. It's the pressure in the line that makes starting a pig. That's why if you don't have an easy start valve you have to pull the trigger to release the pressure when you pull start it. Seeing as the flow sensitive unloader removes all the pressure from the system it makes starting a breeze. Saying that the unloader you have chosen VRT310 Isnt flow sensitive. Your not really going to gain much by fitting that unloader hence why I recommend the K1. When using flow sensitive it makes starting easier and the hose is no longer rigid when you let off the trigger. You also don't get that nasty kick back when you squeeze the trigger.

Well sir, I took all the parts out that you had in your video had a heck of a time getting the orifice out, my parts were a little different than that model that you have their but I finally got it all back together and it works great the bypass was my main thing why I did this. Sometimes I walk away from the pressure washer while it's running and worry about the pump getting too hot. So thank you for this video is the best one out there on how to bypass the original unloader😊

at 16:14 rather than putting a screw on that seat, can i simply dial down the unloader all the way to bottom
@DirtyDriveAway9 ай бұрын
No, I don't think so. Dialling down will probably still cause the unloader to operate at a specific pressure. This will then cause issues with the external unloader. I'm not 100% certain as simply dialling it right down isn't really the best method as your not technically isolating the integral bypass chamber. You could try it, but you don't want the 2 unloaders conflicting with each other. That's why it's best to just completely isolate the internal valve. This way, you know the external valve will do the work properly.

Hi at 12.45 the one that you are removing, is that a starter jet.
@DirtyDriveAway9 ай бұрын
It's what governs the pressure, without it the unloader has a hard time knowing when to go in and out of bypass. It's combined with the shutter jet to close off the outlet and thus build the pressure to bypass the water. Since this is installed in the external unloader there is no need for it.

@sivucit yes the ezstart valve releases some of the pressure in the pump whilst you start the motor. The K1 will dump the water out the bottom, I run this to a drain on this washer as I don't feed it from a tank. The K1 unloader makes the whole machine easier to start and operate.

@sivucit the K1 doesn't have a built in ezstart per se, but because it doesn't trap pressure in the system it makes starting as easy as if it did have ezstart. Mine doesn't have the ezstart valve so I just pull the trigger on the gun when pulling the start cord. I don't need to do that with the K1, I just pull and it starts.

Do you still have full psi pressure with the bypass unloader?
@DirtyDriveAway9 ай бұрын
Yes, you adjust the pressure using the bolt on top. Once set it's locked off with the lock nut. It only goes into bypass when the trigger is released. Using these kind of unloaders also eliminates the nasty kickback you can get when squeezing the trigger.

Thanks so much, with your help, i modified mine and everything went well. 2 questions please. 1. when i set the unloader, i did it with white tip for around 2500 PSI, then when i changed the tip to Dewalt turbo nozzle, the PSI jumped to 3000 psi.. is that normal.. in otherwords, what size tip should i choose to set the PSI on unloader. 2. i removed pressure washer thermal relief valve and put a plug.. I assume for our setup thermal relief valve is no longer needed right. Appreciate your help, cant thank enough and i dont thing, any body in youtube explained this better.
@DirtyDriveAway8 ай бұрын
1. You need to use a nozzle that is the correct size for the pressure and flow rate of the machine. The coloured tips are often not supplied to spec and thus don't always produce full pressure. My machine is 3000psi at 10lpm and uses a size 030 nozzle. This nozzle will give me the correct size to achieve 3000psi at 10lpm. The unloader is set by this nozzle size on my machine. The thermal relief valve is no longer needed as it would never get hit enough to work. Removing it is not an issue. If you let me know your psi and flow rate of the pump I can tell you the correct size nozzle.

@DirtyDriveAway8 ай бұрын
@sivucit if yours is the same then yes an 030 is the right size nozzle. Angle doesn't matter but I typically setup unloaders with a 15degree. If you have a gauge fitted and the correct nozzle increase the pressure on the unloader until it gets to 200bar/3000psi. Yes you should still have a dribble of water coming out the bypass when you have the trigger pulled. You won't see it if you have a hose connected so you'll need to monitor it straight from the unloader. Once you release the trigger the K1 will go into bypass and dump all the water out the bottom of the unloader. So when your working and have the trigger pulled and pressure/water coming from the nozzle you should still have a dribble coming out the bypass port.

@@DirtyDriveAway Thanks so much for all your help. Last Q, K1 is flow control unloader valve. What you have before the one that comes with unit is pressure trap unloader valve, in case of pressure trap unloader valve, do we set the PSI in unloader the same way as K1 (flow control unloader valve) except the bypass part (becaise it has internla bypass)
@DirtyDriveAway8 ай бұрын
@sivucit yes, it just reacts to the change in water flow. I.e when you let off the trigger it knows that flow has stopped and opens the bypass port. In a pressure sensitive it acts to the increase in pressure. The downside to trapped pressure is that it holds working pressure in the hose and thus keeps the hose rigid and the trigger and connections etc under constant pressure. You also get that nasty kickback when you squeeze the trigger and harder starting with trapped pressure.
@grant79349 ай бұрын
Excellent videos and advice (I'm considering this as a new business). In your video, "Starting a Pressure Washing Business", you mention the importance of flow and pressure but then say you usually use only half pressure. Therefore, wouldn't it be cheaper to use a smaller engine for less pressure? I'm assuming an adequate pump, eg 35 lpm, could be connected to a smaller engine. but this may be incorrect. Keep up the good work.
@DirtyDriveAway9 ай бұрын
Hi, no you can't fit a big pump to a smaller engine as the motor simply won't power it. For example the common GX390 engine is usually coupled with a 200bar @ 21lpm pump. Or it can be a 250bar @ 18lpm pump. However the motor is not strong enough to do 250bar @ 21lpm. The pump needs to be coupled to an adequate size engine. Although for run of the mill cleaning tasks using a flat nozzle I use reduced pressure/throttle, if I was cleaning block paving I would go max RPM especially when using a surface cleaner.

Looking at doing the same on a clarke pls265b, 13hp 3263psi 16.5lpm machine and replacing with a k1. Obviously swapping the k1 in you lose the regulator for the pressure, ive been told that with a k1 installed the best way to lower the pressure when you dont need it full is to just back off the throttle? Or is there another way to do it?
@DirtyDriveAway8 ай бұрын
The best way to lower pressure without sacrificing flow rate is to use larger size nozzles. If you back the throttle off yes the pressure drops but so does the water flow. If you don't need all the water flow then yes by all means drop the revs down a tad. If however your finding that you don't have enough water flow then it's best to keep the revs up and use larger nozzles.

@DirtyDriveAway does the same apply to turbo nozzles? Would the correct nozzle for rinsing/chemical application(largest angle) be okay or should I get larger ones too (sets of the colours you get, worked out my correct turbo nozzle as 4.5 when looking at getting a suttner 357.1?
@DirtyDriveAway8 ай бұрын
@Simmons2193 so the actual output of your machine will vary depending if your feeding it from a tap or suction feed from a barrel. The max operating pressure on main feed is 207bar @ 16.5lpm providing the garden tap is supplying that amount of water. If its barrel fed then it's 200bar @13.5lpm. I would base your max pressure on around the 200bar mark. How are you feeding your washer.
