Undersized injector on 8gpm

Shock your SH when temps get low & you will see a improvement.

Iā€™m in Louisiana. It rarely gets under 70 here. When it drops below 60 people start freaking out. It still feels like summer time atm.

Have you tested your injectors to see what theyā€™re pulling? If I remember someone with a 8gpm machine was pulling 18:1 ratio with a 3-5gpm injector (2.1). That would give you about .7% hitting the wall which is plenty. Maybe a little longer dwell time and might have to hit bad areas twice. With your smaller pump you were probably pulling 9:1-10:1 so your dwell time was less but it also takes you 2-3 times longer to rinse.

Your diagram is missing a degreaser bucket connection

The 4 way from hydrochem is set up way differently. Very elaborateā€¦check valves, manifoldā€¦ect but it has a $250 price tag.

Diagram is just using $30 worth of 3 way ball valves to select diluted hw mix and straight bleach for gutters when needed.

Usually 3 sides of the house very diluted hw mix would work fineā€¦it would be nice to go to a hotter mix for the north side by turning a valve

No I havenā€™t. I will do this within the next few days while I have some down time. What you said seems about accurate. Iā€™ve probably just gotten used to working with a hotter mix with 5gpm then the 8gpm is capable of.

Pardon my ignorance but what are you shocking your SH with. We almost never have weather in the 40ā€™s this time of year in TX but we do this year so I need to bump up my game. Thanks

Trichloro-s-Triazinetrione works better than calcium hypoclorite but only add 1TBS per 5gal max depending on initial % of SH I have added as little as 1/4 cup to 65 galā€™s [pre dissolved] & it bumps up alkalinity a considerable amount. Just google Trichloro - s - Triazinetrione & you will find out where to buy it. Good luck to you

Is the 4 way from Hydrochem the DS set up you were telling me about a while back? Granted, you may not remember that conversation at all, but you mentioned one of your suppliers had a DS ā€œproportionerā€ style set up.

Yeah it is. I only buy a hydroxide mix and citric acid from them, and a degreaser. I donā€™t get up there often. Buy SH from a different place and eliminator.

Iā€™ll email the rep and see if he will send me a picture of it

Thanks, Iā€™d love to see it.

I run 5-8 gpm general hi draw with my 8gpm machine and my house wash is 50/50 with elemenonator and 200 ft of pressure hose.No problems doing it this way

Whatā€™s your actual draw rate?

Not sure,I have never checked it.I will mess with it this upcoming week and see

Did this ever work out? I was thinking about doing the same thing but with house mix and another mix for downstreamingā€¦
