I have been considering something I know others have done in the past,.and I think some still do. Except I'm gonna add a twist to it via my remote unit.
I've seen many talk about force feeding a downstream injector to get a stronger concentration,..especially with 8-10 GPM. I never had much interest in the topic until now.
I bought an Udor 10 GPM pump to replace my 8 GPM pressure washer pump,...and I am a little worried about my DS rates for those tougher mold jobs. I know I can drop down to even a 2-3 GPM soap injector,..but that is really gonna choke my flow,..but even at that I don't think I'd need it all that often. But still an option.
There are times when spraying concrete or really bad siding or dryvit and I need a little stronger mix,..and 10 GPM and DS'ing may not be the best choice,..and I have resorted to the roof rig for certain jobs in the past..but as I said I'm having another look into force feeding the injector. I didn't realize they actually made units just for this,...or at least they did. And, looking through old threads I see it's been discussed and done for years.
I never had much interest due to not having any real issue,..but with 10 GPM I am gonna get it together and have it as at least an option for "Those" jobs.
I am going to use a 1 GPM pump and place it between the remote unit and the SH tank,...and I am going to wire it into the remote unit so the 12V pump will be on when the remote solenoid is open,..when the solenoid is closed.the pump will be off. Theoretically,..shoving 1 GPM into the line will give a 1:10,..and that should fill that gap I'm looking for. I know other guys were using 2 GPM and more but I don't think that's necessary for what I'm trying to do. Some of the guys were talking about being able to DS roofs by force feeding the injector. Well,..I don't really want to run the strong a mix through my expensive HP hose,.that isn't made to handle these percentages. Interesting though none the less.
I am actually gonna tie it into the injector feed line so I can use it when necessary and be able to use the soap injector as normal when the "forced injection" isn't needed. But want to be able to simply turn a valve to utilize it when necessary. I'll just have the pump on switch so it can be controlled by the remote only when I want it to.
Just another way to fine tune my application methods.
I was getting 1:17 ratio by regular DS'ing,..if I can actually get 1:10,..that will be quite a jump,..and be able to use one hose for soaping and rinsing, ,..and be remote controlled to boot.
I think the solenoid when closed will keep the 12V pump primed,..and even at that,.the soap injector itself will still be pulling, and that should also help with any priming issues.

This sounds interesting. I'll be looking for your post about how this works.

Yea Brett,..I will keep the board informed how this works out. I think it's fairly straight forward? I think the biggest issue is having 12.5% sitting in the 12V pump through the course of a job,..but used only when a stronger mix is needed it may not be as a big an issue,..we shall see.
Hey Eric,..I know others have done it,..I see it come up every now and it recently came up over on PWI,..and I gave more thought and did some searching on the subject.
*I actually plan on using the Seaflo brand pump,..like I used last season in my spot sprayer,...and it handled 12.5% extremely well. And it sit in those pumps the same way it will sit inside this "SIP" (Soap Injector Pump)

If I hit a real nasty siding I leave the injectors on and then just hook up the XJet. After that side is done I uncouple the X from the end of the wand and continue soaping the rest of the house.

Here's a video Jim Faulhaber did on a force feed D/S injector

Thanks Art,..there isn't much information on this idea,..but most everything I see is positive,..in fact you don't see anything negative enough to warrant NOT doing it,..if it's something you can use. Not sure why it never took hold mainstream. I'm gonna find out though,Ha,Ha,...May be just a niche' most don't feel needs filled.
I'm not gonna have the 12v pump turn on and off with the pressure switch though,..it is gonna turn on and off with the solenoid. I could also just let the solenoid to shut the pump off,..still allowing for low PSI rinsing. We shall see. I am going to use a 1.3 100 PSI pump. My original idea was to use it only when I felt like it was needed,..because alot of my regular customers don't need much SH hitting the surface anyhow. But new customers,..and a few other applications could stand a boost in percentage. New idea for me,..so I'm sure there will be changes along the way.

I like this method. For me everything is already on the truck. Anything nastier and I'll pull out the roof mix hose.

This could be the answer. If you can get a strong enough mix it will be a big time saver.

Hey Michael,..I'll be happy if I can get 1:10,..that'll be quite a bit stronger than the 1:17 I'm used to by DS'ing. I know some guys have stated they can get 3%-4% strength by adding a 12V booster,..and likely could,..if the smaller GPM machine was used and you can get the soap injector to put 2-3 GPM into the stream. I was getting 1:17 with an 8 GPM machine,..it was always enough for a basic house wash,..but I'm moving up to 10 GPM and am a little leery of the draw rate. And is why I am going to go this route.
Never liked an X-jet so that's not even an option,..I'd rather use the roof rig ,..which I have done.
From talking to a few others that run 10 GPM the DS rate will be ok for house washing,..but I want to be able to boost the strength when need be to fill that niche'
It will be wired in and ready to go on every job,..will just have to turn it on.

The other advantage of force feeding is it could open up a couple other applications I currently do with direct application,...
(1) Applying stripper to failing semi-transparent stains,..where my current DS rate isn't enough for this application,.this force feeding may take care of that?
(2) Two stepping houses,..An acid first then Purple Power directly over the acid is like magic on those houses that have that grunge under the soffit,...and even sometimes the whole house. Would be nice to two-step these by DS'ing,..rather than direct application. I'm fairly certain I can DS the acid this way,..but the PP will likely still need direct application,..DS'ing just aint gonna get it.
It will be close for these applications,..I could also use a 2 GPM pump,..I know others have done that. I have also been considering using a larger soap injector,..a 5-8 GPM rather than the 3-5,..that would allow for better injection I think and would also free up some flow.
*I'm also wondering if removing the orifices from the soap injector will allow a larger GPM pump to be used,..say like 3-5 GPM ,..maybe removing the restricting orifices will allow for more chemical to be injected into the stream? After all,..if the injector is being force fed,.the draw from the orifices isn't really needed.
I love the experimenting and tweaking.

I think it was Pressure Tek that was selling that about 8 years ago.

I know Envirospec had one out,.. And I also seen Paul Kassander talking about them before over various boards as well. Maybe it's the 12.5% going into the 12V pump that makes people shy away from it? I ran 12.5% through my little handheld sprayer all Summer long,..used (2) pumps. And using sparingly? It may not be an issue for me. The pumps I buy are $35.00 for 1.3 GPM and 100 PSI,...the ones I used in my handheld were 1.1 at 70 PSI,..same pump though as a whole.
As I said,..we shall see.

That was it! Envirospec. I couldn't for the life of me remember their name. I used them 20 years ago but haven't bought from them in a long long while.
