Downstream Injector for Pressure Washer, Power Washer Chemical Injector Kit, Soap Injector, 3/8 Inch Quick Connect, 4000 PSI

This chemical injector was incredibly easy to integrate into my pressure washing setup. The quick connectors made it a breeze to install inline between the pressure washer output and the high-pressure hose. It effectively siphoned bleach directly from the jug, making my cleaning tasks much simpler.While the product description mentioned adjustability, the instructions didn't elaborate on how to change the siphoning ratio. The bottom portion of the siphon valve spins, which I assume is the adjustment mechanism, but I didn't personally test different ratios.The brass construction is typical for pressure washer accessories, giving me confidence in its long-term durability. Following use, I made sure to flush it with water and then applied some WD-40 after it dried to ensure smooth operation after storage.Considering its low price and how effectively it siphoned the bleach, I found this chemical injector to be a great value. The packaging was standard, but I appreciated the inclusion of Teflon tape, which helped ensure a leak-free connection.

I watched and tried everything i could find for troubleshooting and tried implementing all the ideas. tried placing before wand, didnt work. tried jostling the ball and spring loose, not even convinced there is one. not capable of taking off the nipple to see because it was attached with the jaws of life. no airflow when blowing through either direction. water flow isn't backwards, i tried it both directions. twisty knob does literally nothing at all im convinced. doesn't even pull water so my chems thickness isn't the problem. i tried fixing any possible issues with air tight seals, this did nothing at all. I tried elevating the chems over the injector and the injector over the chems, this also did nothing at all. this "injector" is just a literal scam and should be removed from amazon, do not put your money on it, trust all the bad reviews because you wont be one of the lucky few.

Assembled easy enough. Connected it to my pressure washer gun and cleaned my porches and siding. Worked great.

I wasn't looking for top of the line. Just a good budget piece. This one does the job to spray our solutions at a low cost so great for our company. It's fast and easy to hook up. Should last for quite a few jobs

I had a professional pressure cleaning service wash my vacation home, pool patio and screen enclosure at a vacation home. He educated me on the use of chlorine to simplify the work for great result and long-lasting affect. I have a 4,000 PSI pressure cleaner at home so I researched how to use chlorine in my application. My concern was running chlorine through my pump which could corrode it. The downstream injector solved that concern. Using the black soap tip and lowering the pressure to 2,000 PSI, I injected a mix of 5 gallons of water to 2.5 gallons of pool chlorine (in an ice chest). I soaked my driveway, let it sit for 15 minutes and used my surface cleaner. Wow, great result. My YouTube research also revealed why I was getting streaks after a few months. It was because I was not treating the surface with chlorine to kill the mold. Well, now that the mold is killed, the result of pressure cleaning with chlorine should solve the early return of streaks and yield a long-lasting clean. Highly recommend this injector. Important, run clean water through everything after your job.

The product seems like it would work. It 100% does not work with a 2.5gpm pressure washer. I got it because the injection built in in my pump quit working. This doesn't work either. Has to be a flow issue, im using a true 3/4 hose but my washer is only 2.5gpm.

Better than expected

It worked for the 1st use, then it started self-adjusting to the closed position; it doesn't always pull soap and it back-flows water unto the soap! I had a 7 gallon jug of SH ruined by being back-filled and overflowed with water. This product is garbage.
