Suttner Upstream Pressure Washer Detergent Injector
I liked it so much I bought a second one for my brother!

Easy to put on and take off, cuts down pressure a little but not to much. If you don't stay with the same thickness soap you will have to re adjust the flow every time you change soap.

Perfect-Better than built in Suction
Works great. I was unhappy with the high side suction so I thought I would try this. Easy to install, adjustable metering, and works great. Used it with the 25 foot wand to was the soffits of the house. No problem with suction. Recommend it for all uses.

Injector was easy to set up and fully adjustable to set how much soap you want injected. When soap is not desired simply turn knob and water freeflows thru valve. Used it in a simoniz 3200psi @ 2.6 gpm gas pressure washer and pressure loss was hardly noticeable maybe lost 1/15 of available pressure. By far the best investment for any pressure washer you can buy you get high pressure soap same as the local car wash! Thank you northern tool for a fabulous product!

If you are looking for a true high pressure soap injector like I was you will be dissapointed. At best it is a medium presure soap injector under high pressures the detergent asplication is spotty at best. Hopefully I can find a way to make it work and overcome the hose pressure. when it works it works great, however most of the time the only high pressure that truly is gaurenteed is my blood pressure when I use it. For Light duty low presure it is probably ok and somewhat better than the down stream.

I wanted to apply a dilute solution of a product similar to Simple Green. This product attaches easily to the water supply inlet connection. A simple hex screw adjustment to make it work with your particular pump makes it draw a solution from your bucket or bottle. The screw partially blocks the water coming in to the pump, creating a suction on the draw tube. It does draw a solution but with considerable loss in pressure. I would estimate a 60% loss in pressure with the product engaged. It does spray soapy solution, but not at the pressure I had hoped for.

Had to repair it after 4 years.
I bought this detergent injector many years ago and it wasn't until recently I had a problem with the plunger mechanism. It had sat in my basement for almost 4 years since I had used it and when I tried to get the thing to work it acted so stiff I had use pliers to turn it and get it to seat flush with the housing. I also noticed that there was a "Patent Pending" sticker on it . That was cause for alarm. Anyhow, I managed to get the thing apart with the aid of a moto-tool. I simply ground down the lower lip of adjusting screw and removed the entire part and applied lithium grease at the base after cleaning out the opening on top. The lower lip in my estimation shold have been machined at the factory as the way it''s purchased does not allow for removal of the shaft stem. Anyway,I fixed it and I'm back to pressure washing my fence!! When I look back on it, I do believe this product is a bit overpriced, It doesn't take a lot of work to build one and I wouldn't spend $$ to replace it.

Upstream Detergent Injector
I bought this injector several months ago for use around the house on a 1500 PSI 5hp gas powered injector that uses 2-3 gpm. The injector is very easy to install and use. It can be a little finicky to get adjusted for proper flow, but once it is tuned in it seems to perform well for the day. Overall I am very satisfied and it is well worth the price.

Good but can be improved
This injector is a great product. I have used it on vehicles and buildings with multiple products from degreasers to detergents. For washing cars to trucks it applies the right amount of foam and product where needed. It does however limit the pressure and volume due to a pressure drop at the venturi (small hole where the water goes through creating a vaccum to draw the product into the pressure stream) and the small constriction. This reduced water volume labors the pressure pump and some cavitation of the pump may be occuring. A lever handle should be installed on the on/off position of the plug valve to provided ease of on/off. An adjustable bypass around the venturi should be provided to provide the requsite volume to the pump while still providing the right amount of product in the pressure stream to prevent pump cavitation.

Suttner Upstrem Injector
I purchased this injector hoping it would solve my problem of getting detergents and chemicals onto my jobs. After a little adjustment, it works great !!! Now I can spray my soaps, cleaners and other chemicals directly onto my work sites and not have to switch tips, climb down the ladder, or use another type of sprayer. I have already reccomended this piece of equipment to others.
Try it yourself. You will really like the convienence it offers
