[@rnagil]

Great stuff as always. In your opinion what would you say is the ideal setup for a rig? I'm currently running an AR45 and 2 5GPM machines. Will upgrade soon to an 8GPM but not sure if I should go the injector route or not. Any advice will be appreciated

[@allproexteriorservicesllc5338]

Sounds like a great set up. I am running the 8 & AR45 and love this set up. The 5.5 GPM tends to pulls more SH in case you need to downstream. But the 8 GPM is a beast for surface cleaning. Focus on what would make you more efficient. Hope this helps

@All Pro Exterior Services LLC. I've learned quite a lot from your videos. Correct me if I'm wrong though. On your second test with the 1.8 injector. It pulled 6 gallons on a half gallon of chem. Therefore, it would then pull 12 gallons if it were a full 1 gallon of chem. When you subtract the 1 gallon of chem from the total, it becomes an 11:1 ratio for both. So why wouldn't the math then be as follows: 12.5 ÷ 11 = 1.136% (rounded to 1.14%).

[@allproexteriorservicesllc5338]

Thanks for watching & supporting the channel. You are correct & I was using quick math. Thanks

[@bennybenny7217]

You don’t subtract the gallon. C1xV1=C2xV2

[@MrDarrinSmith]

When I tried the 1.8 injector on my 8.5 gpm it seemed like it was really stressing my machine and i didn't like the sound of it so i didn't use it and went a little bigger orfice high draw injector. Not sure my ratios but it's fine for house wash and my machine seems to be back to normal. Any thoughts on that?

[@allproexteriorservicesllc5338]

That was my original concern with the strain. I spoke with a few people and they have been running the 1.8 for a while with no problems. Mine doesn't sound much difference than the 2.1. Hope this helps. Thanks

[@bryangoldsmith1238]

Thank you for all your informative videos. Just wondering what your big pressure washer is … 8 or 10 GPM? I noticed it’s a GX 800 motor, I’ve never seen that on a 8gpm machine… Thanks

[@allproexteriorservicesllc5338]

Thanks for watching!! It is a Sudor 8 gpm pump, but I am getting about 9.5 gpm. The reason I didn't go with the 10 gpm pump, is because it would dilute my soap too much.

[@577buttfan]

@@allproexteriorservicesllc5338 Ahhhh you dont need that much soap anyway :)

[@blakenasser7166]

Hey man great videos! Just curious why does the 1.8 pull more chem? Isn’t it smaller than the 2.3?

[@allproexteriorservicesllc5338]

The smaller orifice restricts the water flow allowing for a stronger mix. The bigger orifice allows more water which weakens the mix. I hope this helps. Thanks

[@pressurewashingbysterlingw9883]

Hey man have you tried adding check valves on your injectors? Last longer and increase your draw.

[@allproexteriorservicesllc5338]

I have not, but I have heard mixed opinions about the check valve. If I can find an adapter for a reasonable price, then I would do some testing. Thanks

[@troykisner4507]

Good video! I believe you have to divide by the total number of parts which are gallons in this 1.8 injector case. You have your bleach which counts as one part and you're other 6 gallons for a total of 7 gallons. 12.5% ÷ 7 = 1.79%. For instance one gallon of 12.5% bleach and 1 gallon of water - 12.5 ÷ 2 = 6.25% bleach..... I had that last digit wrong but it's corrected now. 🤓

[@MannyAguilarJr]

Yeah people mix up parts and ratios

[@investnow8560]

The video illustration is correct. The 1 gallon was incorporated into the tank for a total of 6 gallons. Hence the subject of the video "Chemical Injector Draw Test". So it was a 5:1 draw.

[@TheIvies04]

Not 5:1 as only a half gallon was drawn to get 6 gallons. Doing the full gallon would draw an 11:1 with 12 gallons

[@ZellionAngel]

That gallon of bleach was in the tank that he counted as 6. It was 5 gallons of water and 1 gallon of 12.5% bleach.

[@johnwitt586]

What would be the best % you would like to use on dirty vinyl siding? When I do the same teat as you did I either get .69% or 1.5% I decided to use 1.5%. I'm wondering if it's to hot of a mix?

[@allproexteriorservicesllc5338]

I would go with 1.5% in your situation as well. Prewet the vegetation. Thanks

[@johnwitt586]

[@johnwiechel]

New guy here. I have a 5gpm pump, is it best to run my down stream directly off the pump, or is it better to put it onto my hose reel?

[@allproexteriorservicesllc5338]

I would run it close to the hose reel to prevent any back flow of chemical. Thanks

[@cartervalentine2368]

I'm very confused. How does the smaller mm injector allow more chemical to be injected

[@allproexteriorservicesllc5338]

A smaller mm injector restricts waters flow. A larger mm injector allows more water diluting the SH to a lower percentage. Hope this helps. Thanks

[@serj9886]

Great video Stupid question. The bigger orifice size means more chemical suction? Trying to figure out on my 8gpm machine with 200ft of hose Thanks!

[@allproexteriorservicesllc5338]

You would think so, but not the case. The smaller orifice draws more chemical. The bigger orifice injectors allow for more water flow. Thanks

[@eduardodelatorre9227]

Aren’t you supposed to subtract the 1 gallon of chemical from the total number of gallons being drawn? So if you got 6 gallons total that would be 5 gallons water to 1 gallon of chemical making it 5:1 and not 6:1? So 2.5% instead of the 2.08%?

[@Gamer-kd9ou]

He should be correct. Let's assume the total was 2 gallons instead of six. If you subtract by 1, then 12.5% divided by one would still be 12.5% while dividing by two would yield the correct result of 6.25%.

[@user-yy4up8qf5m]

No becase it's a dilution ratio! Let's say we used 1 gal of SH in 1 min and the total was 10 gallons ( both water and SH. (So there has to be 9 gallons of water and 1 gallon of SH in the tank. Now we have 1 gal of SH concentrate that became 10 gals of ready to use in a period of 1 min. So if you do this for 10 minutes... your gona have 100 gallons of ready to use with 10 gallons of SH in the mix. Written as 1:10. Where 1 is the SH in gallons and 10 is the total SH + Water. (The diluted amount).

[@whitewashexteriorcleaning5333]

You did the math on the first injector wrong. Not sure why you multiplied your gallons x2. If you would have taken it 12.5% Divided by 9 on the 2.3 injector you would have had a 1.38% mix. Your test on the 1.8 injector you did it the right way and came up with a 2.08% mix. Informative none the less , but just thought I'd mention that.

[@allproexteriorservicesllc5338]

The reason I multiplied x2 on the first test is because the gallon was half empty. So it would have taken 18 gallons to empty the entire gallon jug. This was a draw test not a flow test. Thanks

[@donbrock5792]

What brand of injector do you use?

@All Pro Exterior Services LLC thanks for the reply. Also I had another question. The 1.8 chemical injector is rated for 2-3gpm will that effect my 4gpm machine. Will it still work ?

[@newviewnc]

Here’s a question for ya. I’m upgrading my 4gpm to an 8gpm. Can I use the injector from my 4 on my 8??

[@allproexteriorservicesllc5338]

I am using the 1.8 injector which is rated for smaller machines. However, you will lose flow by going with a smaller injector. Thanks

[@fbombpowerwashingllc]

4gpm and 8gpm have different jet size inside the injector. If you take your quick connect ends off you can see inside the injector there is a small hole and flat slot. You can run a 4gpm injector on a higher flow unit but you lose a lot of flow to. Being restricted. 8gpm injector jet hole is much larger inside. That allows proper flow. 👌

[@premierpowerwashing6634]

Hey man. Are you still running the 1.8 on this? I recently upgraded to an 8gpm from a 4 and use the super suds sucker. Just did a test and I'm spraying a .62% If I throttle down I can spray .83%. Gonna try a couple different orifices that it comes with again tomorrow.

[@allproexteriorservicesllc5338]

I had to go to the 1.8 to get a decent strength to clean anything. 2.3 is ideal if you can pull a good ratio. Thanks

@@allproexteriorservicesllc5338 , thank you for the quick response. I’m new at it and wanting to learn the right way. I have a 4.2 gpm 4400 machine with an adjustable injector. I can’t seem to figure out the % SH hitting the surface, vinyl siding that is. So do I measure the gallons of water after the gallon jug is empty to get my %?. I’m totally confused. The injector is a 2.0 up to 5. Does this make sense.

I was think I could just pull straight SH from a tank or bucket.

[@allproexteriorservicesllc5338]

@@artbentley4887 It is an easy formula. Take the SH % and divide by the gallons after the gallon jug is empty. Example, if you have 12.5% SH and draw 10 gallons including the 1 gallon jug then you would use 12.5/10= 1.25%. Hope this helps

[@alconyers2003]

I swear your calculations was off. But oh ok

[@joeslatt]

It was off. First test was 9 gallons, second test was 6. The only right answer means the second result should be 50% higher than the first, which is not what he got. In the first test, he multiplied the total gallons (9) by 2, in the second test, he did not. Test 2 actual result was 0.125 divided by (6 gallons x 2), or 1.04%. First test was 0.125 divided by (9 gallons x 2), or 0.69%. And 0.69% x 1.5 is 1.04%, so that's the proof that (a) you got a result that you thought you should get and (b) that his 2nd calculation was incorrect.

[@fbombpowerwashingllc]

how to check gallon test vs sh% draw test... Start with a five gallon container full of water hook your down-streamer to it and add the amount of pressure hose that you usually use. Start your pressure washer and spray your gun into a fifty five gallon container. When it has fifty gallons in it, stop. Measure how much has been drawn from your five gallon bucket. Let’s assume three gallons. So you have 47 gallons of pressure wash water and 3 gallons of soap. Let’s call that 47÷3. That equals 15.6 to 1. If you are using 6% bleach, divide 6 into 15.6. Answer? .3846. You are getting .38 percent bleach on the wall. Now that .38% downstream injector % out put.

[@allproexteriorservicesllc5338]

That is another option, but larger scale. Both test will produce the same results if you break them down. Thanks & good info

[@fbombpowerwashingllc]

@@allproexteriorservicesllc5338 this how I test, to see what I get and I also use only the 1.8 downstream injector. And even tried the highflo injector that they claim that draws 3% . But really doesnt... their website only states 30% to 40% increase, so let's say if I'm shooting 1.38% with high draw 1.8 and then with check valve injector add say on high side 40% to 1.38%... 1.38% + 40% = 1.93% .. with 12.5% sh.
