How to Use a Super Downstream Injector for Pressure Washing

Downstream injection introduces chemicals into the system after the pump, so no chemical is run through the pressure washer pump itself. In this demonstration, Micheal Hinderliter teaches you how to use a downstream injector for pressure washing and why you actually need this super downstream injector.

Use the Super Downstream Injector to bypass your pump when applying corrosive chemicals, detergents, or acids to help maintain a longer life on your pump. Works with up to 300 feet of the pressure hose.
Prevent debris from entering the pump by using a Chemical Strainer. Soap enters through the strainer, preventing debris from entering the pump. This is a durable alternative to lightweight soap strainers. The step-down hose barb will attach to either 1/4" or 3/8" hose.
An internal brass weight keeps soap strainer at the bottom of the soap container. It includes built-in stainless steel and Viton check valve to prevent water flow back into the soap strainer.

[@matthewbalg6097]

I have 200 feet of hose and as you said it doesn't draw but what I found that works is idling my machine down a bit and it pulls hard enough to collapse the bottle ! Does affect the distance a little but not to much

[@kevinwenger2049]

Why couldnt you put your injector right before the gun? Say you are doing a tall building and cant get your machine with in 150 foot, but you have a 5 gallon container that you can easily bring to where you are working. Are you going to get a better detergent pull from right next to the gun?

[@xtremepowerwashing1815]

The closer the injector is to the gun, the stronger your mix will be . 👍🏻

[@Powerwash]

That is great feedback Billy. Results do vary because of the variables that can affect the draw strength. Thank you for commenting.

[@EBPization]

Could you put a downstream injector in line with a garden hose with normal water pressure and have it draw out soap from a bucket?

Can a downstream injector and an unloader be connected at the same time? So a downstream injector won’t work with 150’ hose?

[@colbyreneau7018]

Hey man, I have a quick question for you. You are way more knowledgeable about this PW stuff than me. I have a 4200 4gpm Honda GX390. My question to you is, how can I downstream through 150' of high pressure hose? It will only draft from shorter hose lengths. I've seen alot of your vids and know you have the same machine. And no way you only use 50 feet of hose. What's the secret?

[@zxyturtlezz1171]

In the same position as you brother.

[@tylerhovdebo]

Do you know which downstream injector I would use for my 10 gpm 3000 psi pressure washer I will have a 50 foot, 5/8” whip hose from the machine to the hose reel And 1/2” pressure hose for the first 100’. And 3/8 for the last 150’. I want to be able to put the downstream injector nearer to the reel on the whip hose. If there is no 5/8 ds injectors. I will reduce to 1/2” a few feet before the reel for the injector placement I want to inject 2-3% I as well have another 10gpm unit in my trailer that I am going to siamese with the first one so I can do 5 storey hotels and other high buildings with 20 gpm flow Any help as to correct my design Locate the proper ds injector Would be fully appreciated

[@Powerwash]

This is a very unique situation. We do sell a 10 GPM 1/2" chemical injector that you could use for this machine. However, the issue is that through 250" of hose, the backpressure on the line will probably be too heavy to get any chemical draw. Your best option to get that kind of draw with that much pressure hose is to either move the chemical injector up through the line so the injector itself has less pressure hose to work with, or to cut down about 100'-150' of pressure hose on the line. If you were looking to order this injector, please give us a call at 800-433-2113 as it is a special order and cannot be found on the website.

[@every_thing_wood1251]

My question is, if you're using this for say house washing. And you want a certain percentage mix(idk maybe like 2%) how do you achieve that? I don't understand it. If its 1:10 or whatever ratio, how do you get the right percentage? Or do you just guess and check?

[@sethburkhart1021]

If it’s 1-20 the best you can get with 12.5% bleach is like 3/4 of a % SH. With the adjuster valve all the way open. Half open would give you have strength. You just have to calculate the 100% open and calculate a proportion. Google how to calculate a proportion maybe. I’m still wondering how I can get up to a full 1% strength if you are only able to shoot a 1:20

[@DoctorRickSanchez]

What would cause a downstream injector to suck water in vs pulling the chemical? It is not mounted backwards and the ball/spring was just cleaned out with wd40 I'm getting frustrated..

[@Powerwash]

I am not sure I understand the question. How is it sucking in water. It is supposed to draw / suck. Pardon the question but is the draw tube in the chemical solution?

[@Varsitelle]

A regular downstreamer can only at most pull 2% of SH, does this super downstreamer pull higher than that?

[@Powerwash]

It is going to be about the same

[@NoName-be5ir]

I have this type of down stream injector and I’m not getting anything. I can drop the injector in water and blow in tube and get air bubbles, and as I close it the bubbles stop. I set it a lowest pressure with a black tip and slot went up in pressure and nothing. Tried it with out a tip and nothing. I have a 4gmp , 4000 psi machine. The injector was listed for 3-5 gmp . Any ideas. I like the roll over tips, will be ordering that .

[@kman4842]

Thank you. Very helpful.

[@SpeedyChevy72]

by putting that down stream injector after the pump, wont it decrease the pressure? Also say you didn't want to use soap at all on a job site, could you tighten/close that metering valve so it wont suck in any air?

[@577buttfan]

You just put a shutoff valve on it.

Move it closer to the end of the hose. Insert at a quick coupler

[@seattleprowash5464]

I tried this it doesn't work, even with soap tip

[@Powerwash]

Something with you set up is not right or you have a downstream injector that isn't working properly. Check the arrow on the injector to make sure the flow of water is going thru it in the right direction.

[@rkpowerwashing0429]

My husband bought an injector but it does not suck up the chemical, what it does is that the water comes out of the injector hose, what is happening?

[@Powerwash]

You need a check valve on your strainer and it only works with low pressure with the black nozzle. If he is using high pressure it will not work.

[@freeagent6203]

can you add 2 injectors inline to get up to 1 to 10? or even 3 injectors?

[@Powerwash]

[@1975DLR]

Thanks for the video. I think I understand a little better how the venturi works now. And the examples of how back pressure can happen are things I wouldn't have thought of. To overcome the gravity back pressure would you need two sections of hose?Thanks again from Kent, WA

Hi. What is the working pressure of the pressure washer?

In this video it is 4000 PSI at 4 GPM

[@rickdel73]

Thanks for the informative video!! Great explaination of how the downstream injector works.

[@j0shua40]

do they have these installments for ryobi pressure washing machines

[@Powerwash]

I don't know

[@WalterFieldingJr]

From varying sources, maximum suggested length of hose for the Venturi effect to stop working for a chemical injector is in the region of 10-20m (33-65ft). I’m not saying these sources are correct, as there is nothing that backs up their conclusions. Your estimate of 150ft (45m) is more than double, which suits me as I have a 30m hose, but I obviously want to make sure. I am about to buy a foam injector actually which I think works roughly the same way but at a slightly higher pressure. The foam gun nozzle has a smaller aperature than a standard detergent nozzle. I can’t find anywhere a formula that I can use to calculate maximum hose length using pressure washer specs, nozzle size, hose diameter, hose length etc. How did you calculate the maximum is 150ft?

[@Powerwash]

That is based on experience and recommending a conservative length so the use can be fairly certain it will work. Now I have run up to 300' with some injector but there a varying factors that can impact the distance. I wouldn't so caught up in finding a exact formula. Just be away of averaged and what will impact and you will will find the performance you desire.

[@WalterFieldingJr]

That was quick 💨. Thanks for your reply. I’ve since found another source saying the same as you, 150ft. Strange how there is differing opinions on this as you would think the science of the whole thing would prevail. Out of interest, are you using a 3/8” high pressure hose or 1/4”? Is your injectors designed and made by you or are they available from other countries. I’m in the UK.

[@bronzzcolt8479]

so I have a question about which way the injector kit was put on, in the link for the kit, the arrow is pointing towards the open end of the quick connect, meaning the nipple end is supposed to be going into the outlet pump. but in this video you put it on the opposite way with the nipple end into the line for the gun.. can you explain?

[@bronzzcolt8479]

did you just swap the ends of the quick connect on the chemical injector?

[@Powerwash]

@@bronzzcolt8479 we may have it plumbed different than you do. The flow of the water is supposed to follow the the arrow. That is how we plumbed it.

[@bronzzcolt8479]

@@Powerwash alright thank you, I was just a bit confused because the injector in the description had the arrow facing the opposite way that you put it on. I’m very new to this stuff so I’m assuming you can put the quick connect fitting and plug on either end of the injector to ensure the right direction of the water flow. Most of the KZbin videos I’ve seen have the fitting adapter on their outlet where they plug their injector into, but the way you have it set up seems to be what I need.

[@Powerwash]

@@bronzzcolt8479 Glad to help. The injector will not work if the flow goes in the wrong direction.

[@raydoucet2805]

I use a Downstream injector, when Water isn't going through the gun, the chemical container fills with water, I need to turn off valve on injector to stop water going into chemical container from washer hose. Have I set up something wrong? Is there a problem with the injector? Running back to Machine to turn off valve is not a good use of time and wastes chemical. Thanks in advance.

[@Powerwash]

Yes, the check valve is stuck. If you can unscrew the hose bard you will find a small ball bearing with a spring inside. Clean it and put it back. It should stop this problem. To prevent this from happening again make sure you rinse after every use.

[@raydoucet2805]

@@Powerwash Thanks very much for your advice.

[@leo-jp8ru]

Sorry for the dumb question i got confused at the "when it comes into the machine itll dilute it" Does that mean i dont need to have a bucket of Bleach surfactant and water mix to put the hose in as the machine will already dilute it ? So i only put the hose in bleach and the machine will automatically dilute it 50/50 or 60/40. How do you control the ratio.

[@Powerwash]

It is not automatic. You will have to adjust the valve on the injector to get the desired mix ratio.

No way to give you a solid answer. The more you use the shorter the life span, the obvious answer. And other factors will depend on the strength of chemicals used and if your rinsing it out after every use. It will be different for everyone. But if you are fulltime guy using it everyday with average strength product, give 3 to 6 months a year if you take good care of it.
