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.
