I am trying to figure out what I need to pressure wash my house.
My pump has what I think is a built in downstream injector, but it says in the manual not to use bleach.
Do I need to add another downstream injector right after the built in injector or what?
I tried pressure washing with just water and it takes way to much energy and water to get that black scum off.
So, I am either going to have to use a low pressure hand sprayer first or use my pressure washer with the same bleach solution.
Not sure…

Yes, you’ll want a post-pump injector, GP is a good brand and they typically run less than $20. Just be sure to cap off the factory one.
