1.1 vs 1.25 Orifice for Foam Cannon

Translated into GPM, the flow rate on your pressure washer is listed at 1.85 GPM......that being said, ratings on electric pressure washers are very often overstated. Swapping out the orifice in the cannon is simple. I swapped the 1.25 out of my PF22 for the 1.1, and noticed a very distinct difference in the consistency of the foam it produced. I'm betting that if you switch yours in the MJJC, you will too. For the record, I'm using a SunJoe SPX3000...rated at 1.76 gpm......which translates into about 1.5 gpm in the real world.

With my little 1.2GPM 2000PSI B&S pressure washer I tried both the 1.25 and 1.1 orifice on my foamer and noticed no difference at all Not sure why...

Why don't you buy a 1.1 and 1.25 and see the difference for yourself. A little difference in GPM or PSI could effect the out put of foam.

^^^^^ THIS ^^^^^

No difference from a test spot

You won’t know until you try and even if someone here had the exact same setup the difference in water pressure or water chemistry could be a night and day difference

I ordered 1.1 with my cannon and even with the SUPPOSED high pressure and high flow that was advertised, I definitely benefited from using the smaller orifice

$7 is $7 but could make all the difference

YMMV

That’s a shame! Did you use the same dilution ratio and soap each time? Maybe the difference is over rated …

I don't know. I used same ratio each time. I couldn't tell a difference, but it wasn't exactly a name brand foamer so many that is why (just a cheapie Amazon MMingle one (had decent reviews fwiw)?! Actually now that I look it came with a 1.5 supposedly (I ordered a couple 1.1 at the same time because I thought I might have an issue)...

The cannon comes with both sized orifices so I will definitely be trying both. Thought I would just check and see if others had a view or preference.

I am almost certain my specs are wrong… by a lot. I think it is 2600 psi at the motor.. and not the nozzle, which would make a big difference.

What did you like more about the 1.1? I find sometimes when I use a rich dilution ratio and the foam is too thick, it is dry and clumps and falls off quickly giving a small dwell time.

It’s hard to describe

It’s partly what you found out

With the larger orifice I had to add more soap to make thick foam and just like you it didn’t cling and slowly run off

I find with the 1.1 it’s easier to cut back on product and get the foam just thick enough to coat evenly but run off at just the right speed and leave the paint wet

If that makes any sense

I can also use several different soaps and get essentially the same results at the same ratio

It’s more forgiving

And my PW specs were misleading as well

Supposed to be 2,300 psi

Not in this universe

And the over 2 GPM claim?

At like 200 psi so that has to mean with the black soap application nozzle

Specs were total garbage

Yeah that makes sense. Did you find you still had the same cleaning power by cutting back the dilution with the 1.1?

A lot of the soaps i have been trying lately claim to be highly concentrated and call for a dilution of 1:5-1:15.. which just means i have to figure out my ratio again...

Yeah, i emailed my PW manufacturer and they barely know their own machine giving me different specs and info depending on who i am speaking with.

..and they might supply you with tiny coloured nozzles as well (1.1) which could mean they can overstate their claims. I think i got the 1.1 coloured nozzles with my machine.. if it is a 2600 psi machine they shouldn't be supplying me with 1.1 nozzles...

I am able to use 8:1 and get decent results

I honestly think I need a new soap though for foaming

I use Gold Class now for bucket wash, just as I have for years

I have also been running it in my cannon as well and thought it did a good job, but I’m beginning to think it’s not

I think a lot of the conditioners or whatever they are called are doing the same thing with foam that they do with a mitt

They create a layer of lubricity that lets the foam look good but actually helps it just float off the surface without doing much cleaning

I have tried a couple of CG soaps just because I can find them locally and I think they might be a bit better as a foam

I think Gold Class is awesome as a maintenance bucket wash and I frequently recommend it but…..

I think I need to order a gallon of Hyper Wash and give that a whirl

As far as PWs go, I’m to the point if it’s not a Kraenzle they are lying through their teeth

My Green Works machine flat sucks for many reasons

For what it's worth, you will like HyperWash better in the cannon and the bucket than Gold Class....I've used both and that was my result

That seems to be the consensus

Right here with you, my local big box store had Gold glass 64oz bottles on sale for $6. I bought 4 of them and still had some at home lol.

They also had the CG bucket bundles with the Mr. Pink, some dressing, and wheel cleaner on sale for half price. I bought 3 of those. I also have been wanting to try Hyperwash as well, but hard to justify the purchase right now with all this soap I have.

I agree on the conditioners, and foaming statement. Slick but doesn't seem to clean well. I do like it though.

Edit: Also wanting to try the Koch Chemie GSF

I think the whole thing with the conditioners really came into focus for me the other morning washing my blue car

I rinsed, foamed with Gold Class, agitated emblems etc, and hit a couple of gecko bomb spots I knew were on the hood with my mitt while the foam was still on the hood

The mitt was soaked in Gold Class bucket solution as well and it felt like it was riding on ball bearings over the hood

At first I thought this is awesome, no way am I scratching the paint, but after rinsing and seeing the gecko bombs mostly intact I thought this sucks, it's not dissolving the stuff or letting the mitt scrub it off

On a whim I grabbed a bottle of CHEAP store brand soap I had casually tossed in a cart to get me to free shipping on a household items order

I had tried this soap once and it reminded me of Blue Coral, it very well may have been the same just rebottled for the big box chain

I mixed up a cannon load a bit on the heavy side and sprayed it on and it was on the thin side but it really clung to the surface well

I got a clean mitt and soaked it with foam from the cannon and went after the spots and this stuff had an exact opposite effect from the Gold Class

It made my mitt feel like it was chemically bonded to the hood, it felt like a clay mitt on a really dirty panel, that grabby locked together feeling you get until the contaminants are gone and it starts to glide

It was weird and really hard to explain but it just felt like stuff was happening and cleaning was going on, whereas in retrospect the Gold Class made me feel like the mitt wasn't even touching the paint

I rinsed the hood and the gecko bombs were gone and after I finished the rest of the car and dried it I went over the hood with a fine tooth comb in the areas I was "scrubbing" on and I found zero marring of any kind

I will continue to use up my Gold Class for light maintenance washes when I am only fighting dust but for stuck on contaminants I feel I need something heavier

Although I probably won't buy anymore of the cheap blue stuff it did teach me a lesson and I will quit going on autopilot when it comes to products I have used in the past

I have lots of half gallons of Gold Class and I will use it for bucket washes for light maintenance but I will be ordering a few products suggested here for more aggressive washes

I plan to get a 1.1mm and give it a go. Cheap enough it's worth a shot.
