Downstream Injector Check Valve

For about the last 8 months to a year I have been using this check valve on my Downstream Injectors. These not only help the injectors last longer, since we are removing the ball and spring, but they also actually make the mix a little stronger. We have been able to clean some porous surfaces that have the black algae stains on them, a little faster than using the injectors how they come. They are available on my store here www.dougruckerstore.com/produ...

Hi Doug is that a 1 psi or less cracking (opening) pressure check valve? Thanks.

[@bluerainpressurewashing6190]

Dough, keep up the great work man. I'm just looking for info on the check valve, where can I get it to buy, trying to build my own.

[@PressureCleaningSch]

We sell them already built. www.dougruckerstore.com/products/check-valve-for-chemical-injectors/

@@PressureCleaningSch Hi Doug I'm confused. Will this check valve work on my chemical injector?

[@frankiii5823]

Dough, i have a Simpson 2800 psi 2.3GPM. Do you recommend your Downstream Injector Kit 3-5gpm or would be be too much

[@PressureCleaningSch]

Doubt it will work on that machine

Would this possibly work in an xjet injector?

[@PressureCleaningSch]

No it would not

[@timexkills65]

Doug can you make one with a 2 way valve with two barbs ? To add two hoses for fleet washing acid and soap cleaners.

[@PressureCleaningSch]

We don’t but you could buy the parts and build one. We have the 2 way and 3 way poly valves available

[@timexkills65]

@@PressureCleaningSch can you put the parts list together for me and I’ll buy it on your website. ? So basically all I need is this unit as shown in the video and then extra barbs and the 2 inlet valve.

Hi Doug, can I install one of these after my fixed injector that’s fixed to the pump?

[@PressureCleaningSch]

No, the fixed injector would need to be removed

[@vcash1112]

@@PressureCleaningSch Ok, So basically removing the hose Barb, ball and spring then installing a plug? Do you have a plug available at your store? Would I be able to remove the hose bard and install a check valve instead? What would be best? plugging the old inject that's fixed to pump and installing a new one or install a check valve? Thanks for replying Doug, you're the best!

[@giantslayer473]

Used my dstream injector to clean my 1st house this past Sat. Went great- although when I switched tips (from black/wash to white/rinse, I looked over at my bucket of SH and the water was back-flowing into the bucket of SH, pouring over the edge of my bucket and thus onto the customers grass, where I (mistakenly) had it sitting. What happened, is this normal?

[@PressureCleaningSch]

No not normal. Sounds like maybe some debris got in your injector. Can you take It apart and check the ball and spring

[@perezleolp]

Same issue here

[@raab8647]

When you are changing tips you’re increasing and decreasing the amount of pressure coming from the wand. That will change the Venturi effect within the injector not allowing the chemical to suction. I imagine water is coming out the tube because there is no ball in that downstream injector check valve but I’m just guessing.

[@HouseWashingRick]

Mr Doug, Ricky here in Cookeville Tennessee, will this work on my injector I have a 4000psi 4gpm belt drive

[@PressureCleaningSch]

hey Ricky, link time no hear. Good to hear from you. It will work on your machine. But The only injector the fitting will work for, if you only buy the check valve without the injector is the General pump high draw.

[@HouseWashingRick]

@@PressureCleaningSch ok thank you for reaching out and letting me know

I having the same problem right now I’m running 200 feet 3/8 pressure hose I just finished set up 11/17/2022 and im running hydro teck 3500 5gpm hot & cool water but my chemical is not strong enough im doing 2 step fleet wash what do you recommend mr Doug u you think this downstream injector check valve is working for me ?

[@KingdomKleenPW]

Will this check valve kit work on my Simpson 4gpm machine?

[@PressureCleaningSch]

It should. Don’t see why not

[@KingdomKleenPW]

@@PressureCleaningSch Thank you sir, I'll pick one up this Friday. I'm excited to give it a shot!

[@69spanks]

Do you think it would work ok with a 4 gallon per minute pump and 200 feet of 3/8 hose?

[@PressureCleaningSch]

Yes. Use the 2.1 3-5 GPM injector.

[@69spanks]

Thank you sir. I remember in some other video I had watched, the guy had problems with the injector and when he called the company and they found out he was using 200 feet of hose, they told him to use the one rated for less GPM than what his pressure washer was, and I just wasn’t sure if it would work for a 4GPM even though it said 3-5GPM (since I’ll be using 200 feet of hose this spring)... I’m still learning the basics, and I really appreciate your videos and all of the knowledge you are willing to share. Thanks again!

[@PressureCleaningSch]

@@69spanks I didn’t have a problem on my 4gpm and 200 foot of hose but I usually only use 150 feet. It could be the machine being used though. Direct drive vs Belt drive and other factors

What is on the inside that allows you to remove the ball and spring?

[@dougruckerstore5123]

When you take the hose barb off the injector the ball and spring will fall out. So be careful you don't lose it. I always cup mu hand under the barb on the final twist to remove the barb.

Realistically how long do these things last out in the field if you're power washing for 6 hours a day?

[@PressureCleaningSch]

A lot of variables come into play but I get anywhere from 6-8 months if I take good care of them

Can you use the downstream injector without spring and ball if I you have the bypass?

Can I do an asphalt roof with this unit.?

[@PressureCleaningSch]

All depends on how bad the stains are. But most likely no.

[@danielcatches9376]

How long did your downstream injector last with the check valve on it

[@PressureCleaningSch]

Never really charted it. They do last longer. But I have a tendency to change things out before they can go bad. So about every 8-10 months I just change them. We keep spares ready to go too.

[@markfermoyle8720]

I researched these and bought one with Viton o-ring and a Hastaloy spring - which seemed to be the best quality. I diligently flushed mine with 5 gallons of fresh water after each job and in about 3 weeks the check valve was no longer closing all the way and back feeding water into my bleach tank as well as cycling my downloader valve. HUNK OF JUNK for the high price I paid. Not sure about the quality Doug is selling here, but that was my experience with the one I purchased elsewhere. ☹

For years, I use an 10:1 injector on a 4 gpm pressure washer. I usually downsteam straight 12.5% Bleach. Five gallons at a time for house walls. If I went with an 2.1 injector... What would the bleach mix be for five gallons... Would that be 3 gallons of bleach to 2 gallon of water...? . also If I went an 2.1 injector with a Downstream Injector Check Valve. What would the bleach mix be for five gallons.. How many gallon of bleach to water in a five gallon mix...thanks... Been going though your videos...Thanks for taking the time...

[@PressureCleaningSch]

Your mix is dependent on the surfaces you're cleaning, strength of bleach your using, GPM of your machine and degree of the staining. For our 8GPM and 5GPM we always downstream full strength. For our 4GPm it's just dependent on the above variables. You have to play with it and adjust a needed depending on what you are cleaning.

[@joeusa4809]

@@PressureCleaningSch Thnaks for answering all these question on this tread... Is there a math formula for the different size injector with different GMP plus how much strength of bleach you want. > Now if you made a list of all the injectors out there, with the % of each water and Bleach would be very helpful. I think a lot people will buy that list. . for example: Using 12.5 bleach in a 5 gallon mix. 20:1 injector will use ? gallons of bleach to ? of water to make 1% 10:1 injector will use ? gallons of bleach to ? of water to make 1% 4:1 injector will use ? gallons of bleach to ? of water to make 1% 2:1 injector will use ? gallons of bleach to ? of water to make 1% .. 20:1 injector will use ? gallons of bleach to ? of water to make 2% 10:1 injector will use ? gallons of bleach to ? of water to make 2% 4:1 injector will use ? gallons of bleach to ? of water to make 2% 2:1 injector will use ? gallons of bleach to ? of water to make 2% . 20:1 injector will use ? gallons of bleach to ? of water to make 3% 10:1 injector will use ? gallons of bleach to ? of water to make 3% 4:1 injector will use ? gallons of bleach to ? of water to make 3% 2:1 injector will use ? gallons of bleach to ? of water to make 3% . 20:1 injector will use ? gallons of bleach to ? of water to make 4% 10:1 injector will use ? gallons of bleach to ? of water to make 4% 4:1 injector will use ? gallons of bleach to ? of water to make 4% 2:1 injector will use ? gallons of bleach to ? of water to make 4%. . 20:1 injector will use ? gallons of bleach to ? of water to make 5% 10:1 injector will use ? gallons of bleach to ? of water to make 5% 4:1 injector will use ? gallons of bleach to ? of water to make 5% 2:1 injector will use ? gallons of bleach to ? of water to make 5%. . Then do the same list but for 10% bleach. . If you sell this idea, please send me a free copy... . O yeah, do one for 1-1/2% mix. > Also, why don't you or other people use the 2:1 injuctors for downsteaming? Would,'t you use less bleach?
