Chemical/detergent Attachment...


Maybe a dumb question.

I have a fairly decent pressure washer with a CAT pump. I've only used the attachment that applies chemicals a few times years ago. I'm assuming the chemicals do not go through the pump.

Recently, I found some bag worms on 27 Leyland Cypress trees I have. I used a portable pump sprayer to apply the chemical but am not able to get the total coverage I want as the trees are 20' high.

I thought I'd use the pressure washer and an extension wand I have.

My question...finally...

Does the chemical attachment dilute the chemical...mix it with water, or does it come out as it is in the container?

I have to dilute the chemical with water before application and didn't want it diluted any further.

Thanks.

I think it dilutes it because the water in the pressure washer pulls the chemical into and through the hose and wand.

You should not need an extension wand. A two-story soap tip should do fine.

You might try one of these:
https://www.zoro.com/buckeye-unfille...00/i/G9783277/

You can usually find them on Craigslist for about $25 or so. We used to carry them around when racing MX to help clean up between motos. They were also a great on the hiway, (or stop light) squirt gun!

They can do 100psi, & 50 ft.

depending on the size of your pressure washer, and the dilution rates the pesticide requires, you may be able to just use your washer to apply. Smaller pressure washers put out a stronger mix.

Be mindful of drift when applying at those heights, particularly people, fish ponds, or other similar concerns downwind.

Be mindful also of how the chemicals will react with any of the seals on the inside of your pressure washer. Those seals are all rubber, and I imagine pesticides wouldn't be an issue, but I think it would still be worthwhile to confirm it won't F**k up your seals.

When you use a chemical injector(chem hose on pressure washer) chemicals don't go through the pump. It is siphoned into the stream after the pump through the venturi effect. The seals never see the pesticides.
