House washing without a trigger-gun or x-jet

I am looking at ways to clean houses, fast!
Since I have 2 guys, someone suggested TWO pressure washers.
One to downstream only, and a high GPM one to follow behind and rinse with.
One guy leads with chemical, and the other one waits a minute, then pressure rinses.
Or, how about this ?
A remote control switch mounted on the trailer using one pump.
Spray on side with chemical, click the remote, and pressure water.
No, that might not work because you can't regulate pressure, and the freaking 300 foot of hose takes time to flush.

The more I think about it, the more I am leaning to TWO machines, since I already have 2 Guys.

But I MAY not even need that ?

The Vari Flow Two Tank System is fixing to be field tested here real soon.

IF it works like I HOPE it will, I will simply use my chemical pumps to wash houses with.

My pumps are 15 GPM each, and two of them are "coming to the party" :D

If all goes as planned, I will be able to dial in almost any chem/water ratio I want.

One 300 gallon tank can have straight 12 percent in it, and the other tank can be water, TSP/Borax, simple cherry, surfactant, or whatever.

Each pump pulls from it's own tank.

The outputs of the two pumps are combined into one hose.
The speed of the individual pumps determine their flow and pressure.

I can control this easily.

The more I think about this, the more I am THINKING I do not need any downstreaming.

I might just take Russ's advice, and get me a high GPM pressure washer, and use Mike Kreisel's excellent idea of a simple ball valve to rinse with ?


Thanks for your advice washing house without trigger gun.
 
Jeff you're right on the noise turn the ball valve just so and it sounds like a 747 taking off.
 
Hey Jason,..although I don't use the ball valve for DS'ing,..I often use it for rinsing,..saves wear on my "Tennis Elbow" for one,..but it also seems to put out more flow than my YRL-51 12 GPM trigger?

Very nice for tight quarters and without having to pull a trigger, there's no kick.

And I got use to the noise,Ha,Ha,..

No trigger gun.

Made this. Have it in my pocket for every concrete job. No gun. Also wash houses with it.

Hey Al,..I made one of those as well,.but not for use with nozzles,..I still prefer a handle for nozzle use. But I made it simply to test the flow against a YRL-51 12 GPM trigger. It seemed like the ball valve alone flowed a noticeable difference,... and upon testing,...I think there is a very noticeable difference in flow with just the ball valve and the 1/4" coupler ,..same as what's on my trigger. So,.I'm not sure why the 12 GPM trigger seems restricting on an 8 GPM machine,..but in my simple testing,.it seems to be the case.

I found that out a couple month ago when my black tip wasn't downstreaming and noticed it worked with just the ball valve open.

I have no issues with DS'ing with any appropriate tip,..I am just questioning why a 12 GPM trigger doesn't flow as good as just the ball valve with he same coupler? At face value it would seem the trigger isn't actually capable of it's stated flow rate?

Jeff
 
The gun is likely capable of producing that much flow, if you can get that much to the gun. Every link in the chain causes friction loss and reduced flow and pressure, all the way up to the tip. The extent of that is determined by what the water passes through along the way. To get the full rated flow while pressure washing, you would have to start with more than that at the pump. It's just the physics of pressure washing, or water for that matter.

Well,..that makes no sense to me at all. Simply because I was testing the trigger vs the ball valve at the end of the same hose as the trigger,.. with the same restrictions and and all?

Jeff
 
Doug and Criss or anyone,
What GPM are you running with the 0040 and 0060?
I used them on a 5GPM today. worked well up to 30'. At 40' it was just a cloud of mist.
 
The valve assembly in the trigger gun will restrict some flow as a ball valve alone is wide open.

Yea,.I get that,as it would seem to be the obvious cause,.....but the gun is rated for 12 GPM,.and the pump is only 8 GPM,.so,.I would assume the restrictions in the valve assembly are taken into account when the factory gun rates the trigger 12 GPM. And in my thinking shouldn't be any different than the open ball valve,..because it should handle the 8 GPM,..especially after 200' of hose.

Irrelevant to me really,.just an observation I made.

Jeff, I understand what you are saying however, the valve assembly in the gun will not flow the same as an open ball valve.

If you've never had the valve assembly out of the gun, take it out and you will see how it can restrict the flow versus a ball valve.

Now, if you where running a 21gpm gun, that would be different.

Mike
 
Yea,.I have had them apart numerous times,..still though,..at a 12 GPM rating ,..it should flow the same as an open ball valve with GPMS's to spare when running only 8 GPM. ,..with restrictions ,...seems to me then that the gun is over rated in it's ability to handle 12 GPM. I know what you're saying abouy an open ball valve having less restriction,. but in my thinking a 12 GPM trigger should also flow with no issue.

I will simply stand by the fact that the YRL-51 is over rated in it's GPM and also agree that the restrictions are the cause. I never doubted that,..as I said,.just something I noticed and observed,..and to simply state that the triggers aren't able to handle the rated out put.

*I'm not arguing the reasoing,.my issue is the rating,..which I said,.is essentially irrelevant,..just a curiosity is all.

Jeff
 
You're dead on Jeff. Most guns are over rated with the flow volume. The ball valve is a straight hole where as the pressure valve in a trigger gun isn't. Water has to flow around the check ball.

I'm not trying to argue either. You provide a lot of good info here!!!

All the best,
Mike
 
Yep, same page!!!

I too have tried the ball valve alone. Just my opinion, I prefer a gun for two reasons, easier for me to hold and the safety factor of a positive shut-off in an emergency.

All the best,
Mike
 
I prefer the trigger for the use of any nozzles A trigger provides better grip,..which equated to safety as you stated. But,.for rinsing,..especially tight quarters and flat work I prefer the ball valve alone,..just seems more effective and better for my tennis elbow. I still rinse up high with the trigger and soap nozzle.
