Pressure Cleaning Equipment {Siamese Kit from Doug Rucker's Pressure Cleaning School}

[@rickwashek478]

I see people talking about simemise to machines, but would be nice to see a video on how you actually do it.

[@PressureCleaningSch]

Well, that’s what I attempted to show in this video.

Thanks Doug good Video…I have 2 of the same pressure washers I want to do the same thing…3300 psi …2.5gpm..I know the gpa doubles does the psi go up…And how do you hook the water source up to both machines???….That would be a good Video…How to completely connect Siamese washers…do you need to hook up each one to water or can you hook one up for inlet and connect them and one is to the hose wand…Thanks

[@PressureCleaningSch]

PSI won’t go up. You’d need two separate water sources. I don’t have any 2.5 gpm machines to do a video on. Sorry. But any time you Siamese them you need two separate water sources

[@robertgraham1821]

Thanks for the quick response…ok Cool…after watching the Video a few more times you basically explained all…I meant any size gpm doing the actual hook up from start to finish and Show the difference in Flow would be helpful…And I can use a splitter on the hose if I only have one water source from house correct…And If I had tanks I would have to use a Splitter as well or have 2 tanks separate…I just did a job where the house had 2 spickets I could have done this and needed the flow for the Job Big Paver and stone Job…Lesson learned…Thanks for the info!!!Keep on Sprayin!!!

[@cvconnor]

What about the flow restriction of trying to run 17 gallons per minute through a 3/8 hose? For example, a high pressure water Jetter/sewer cleaner uses a half inch hose for a 12 gallon per minute for up to 18 gallons a minute flow. it seems unlikely that you will get a full 17 gallons a minute out of a 3/8 hose.

[@PressureCleaningSch]

I've run 3/8 hose on 16GPm before, but wasn't getting full flow. 1/2" hose being larger will get the full flow.

[@guardvids12]

Another solid video! Thanks man!!

Thank you

Now that’s a Golden Nugget oh wise one. Thank yoi

Why thank your sir

[@oside760a]

I plan on doing this! Very inventive.

[@PressureCleaningSch]

It’s awesome

[@ARBoneCollector]

Very good! I will be ordering a 9gpm unit from you very soon!

[@PressureCleaningSch]

Not many left. They are phasing it out.

[@mattgibson7974]

Thats a lot of water to put down at once! With that much runoff do you need to worry about reclaiming? I know Houston is very picky about reclamation, especially on commercial jobs

[@anextday]

Can you do a demo on adjusting a flow actuated unloader....thanks...great vid btw....

[@PressureCleaningSch]

Yes will add it to the list. Thanks for the great suggestion

[@anextday]

@@PressureCleaningSch thanks alot bro

[@hectororiz58]

Hello Doug I’m attempting to plumb 2 4 gpm direct driven machines to the same water tank would I be able to suctioning from same tank or I would need two different tanks? Thanks 🙏🏽

[@PressureCleaningSch]

Direct drive normally don't pull water very well from a tank, but if your's do, then you can plumb them on the same tank. Just two separate water feeds.

[@briantorsell]

Were you running VB10 unloaders on the machines?

[@PressureCleaningSch]

If I remember correctly they were the green spring unloaders. That's usually what I use

[@evanlucas8734]

@@PressureCleaningSch Hi Doug a few Siamese questions firstly do you still recommend Siamesing because I’ve heard that it is hard on your machines. Secondly I have a vrt3 unloader is this a pressure trap unloader or will I need something different if so please recommend. Thirdly can I down stream while being Siamesed, I want two 5.5 gpm machines so would I put a 5 gpm down stream injector on each side of the top of the T on the Siamese hose or one 10 gpm injector at the bottom of the T where the Siamese kit will hook into the single hose your using. Fourthly me wanting two 5.5 machines will mean I’ll have 11 gpm which is a weird number so I usually see down stream injectors, guns,surface cleaners, nozzle tips ,unloaders, etc in either 10gpm or 12 gpm sizes, will I be ok with going with either one of these sizes? I have a 10.5 gun and unloader will this cause problems? Or would even just 10gpm accessories suffice or will I need to find 12gpm accessories. Thanks so much it means the world to me if you get the chance to help.

[@AndrewSierman-x3s]

Why don't have check valves on your whip lines?

[@PressureCleaningSch]

They aren't really needed since the machine already has check valves.

[@nick32141]

So can I take a 4 gpm & a 5.5 belt washers and put them together? And do I need to adjust the unloaders? Will this cause any damage to either unit?

[@PressureCleaningSch]

Yes you can. Make sure both unloaders set to same PSI and no it will not cause damage to machines.

[@nick32141]

@@PressureCleaningSch Thanks

[@emp0rizzle]

Siamese comes from Siam, what Thailand use to be called and in this usage a short-hand term of "Siamese Twins" which is an archaic term for conjoined twins. Came into wide spread use because of the Eng and Chang Bunker who were originally from Siam, came to the US as side-show.

[@haroldferreira3896]

I did run to machines before the only thing you have to do make sure both to machines have the same psi

[@PressureCleaningSch]

Yes

[@nick32141]

By doing this, can I use a standard 3/8 hose that’s 4000 psi? Also, I noticed your Siamese is in between two lines coming off the machines can I hook up directly each end of the Siamese line to the machines themselves

[@dougrucker6783]

Yes as long as the combined GPM is not above 15GPM. I was pushing it on the 17GPM here and really needed to use 1/2" hose for

[@nick32141]

@@dougrucker6783 I’ll be keeping it around 10 GPM so 3/8 should be fine. Thanks.

[@curtislitsair1093]

Very informative! 👏 I have questions about joining 2 8gpm machines that are both at 3500psi. If I want to run hot water, could I get away with using a single burner unit? And would 3/8" pressure hose hold up to 16gpm @3500psi, or would I have to go up to 1/2" ? It's basically for running 48" and 60" surface cleaners, etc... Thanks in advance!

[@PressureCleaningSch]

You could probably get away with one unit on burner but I’ve never ran heat when Siamesed, so not completely sure. W 2 8GPMs I’d definitely go 1/2 hose

[@curtislitsair1093]

@@PressureCleaningSch Thank you!

[@LeathermanSoftwash]

You need to match the BTU’s of your burner to the total flow you want you could use the one burner but you wouldn’t be able to get the water nearly as hot when running double the flow plus depending on the burner it may not handle that kind of flow period 🤷‍♂️

[@nicholashalvis5376]

So once you connect the two wouldn’t you need to change your jet on your surface cleaner or on your wand to accommodate a higher gallon per minute? And what about your downstream injectors on both machines are you just leaving them alone? And your hoses would you be able to use the same hoses you normally do? Thanks

[@PressureCleaningSch]

We mainly use it for rinsing. Yes same hoses

[@nick32141]

@@PressureCleaningSch I appreciate you getting back to me. Thanks.

[@morzaprowashpressurewashin5673]

this set up is ideal for rinsing and for surface washing only

[@benderprofessionalservices9018]

Is a pressure sensitive unloader the same as a pressure trap unloader.

[@PressureCleaningSch]

No. They are different.

[@pressureandsoftwash21]

17 gpm 😲 great job 👏

[@pantac4493]

Would this work if pressure washers are within 100-200 psi of each other? I have non adjustable electric pressure washers. Why is there a check valve on the single hose going to the gun, does it run smother that way?

[@PressureCleaningSch]

Yes should work fine...I misspoke there is no check valve on the hose going to the gun....nice catch...dont really have to have them on the other hoses but I use them.

[@sylc6688]

So the check valve you're talking about are built in this kit right ?

[@PressureCleaningSch]

They come with the kit. Yes

[@rthmop6927]

I see this is a 2 year old comment, but the website specifically says “does not come with check valve” so does anyone know if this is still true ?

[@jhops2552]

Can you Siamese a direct drive and a belt drive together?

[@PressureCleaningSch]

No. Both need to be belt drive

[@hectororiz58]

Hello Dough do they need to be belt drive it can’t be 2 direct drive machines?

I have a 8gpm machine and a 4 gpm machine my question is what size tips I need to have on my wand ? I would be running 12 gpm

[@PressureCleaningSch]

For that many gallons per minute I would just use like I did an open ball valve. But you could get away with a 60 or 70° tip for Rensing. Again we mainly do this on the rinsing large areas

[@oside760a]

I think you since you have the same unloader, you just have to make sure the PSI is the same for both machines.

Just make sure their the same brand GPM/PSi rating
