Downstream Injector Issues

[twolf]

Equipment: Excel with Gaint HRC30 pump (2500psi/3gpm)

I am unable to get the downstream chem injector working. It simply will not draw and maintain a siphon.

It looks like the originial is a 2.1mm oriface. But using another 2.1 and a 1.8 results in the same non-event.

I've tried replacing it with a couple I picked up from Northern but can not get it to draw properly with either. Both are adjustable.

I need it to work with a 24' wand with 100' of hose.

Any ideas?

A 1.8mm injector should work! [hello]

I would have guessed the 100ft hose and/or the 24ft wand causing excess back-pressure. Does it work with 50ft hose and your standard wand?

Mark, if the hose and wand are the problem, is there any thing you can do to the injector to force it to work with that combination? I've had the same problem but had to resort to a shorter hose to make it work.

Twolf, I believe in always starting with the basic. I hope I don't offend you as I do not know your experience or familiarity with downstreaming but I would like to know two things before I even guessed what your problem was.

1) Are you sure you are installing them in the right direction?
2) Are you using the right size orifice on your nozzles to create the draw?

I have never had any problem from 50ft-200ft of hose and both a 4 gpm and 5.5 gpm machine with everything from the cheapos that came with my unit or from different manufacturers of higher quality pieces.

I agree with Ken,sounds backwards or the chemical nozzel is wrong

If the 24' wand reduces the size of hose to 1/4" it will create too much back pressure causing the downstreamer not to work. I bet thats your problem.

You might try a bigger nozzle for your chem applications, less back pressure..

I want to thank everyone that replied - all good ideas by the way - but first and foremost, I want to thank Mark. You were on the money with the 1.8 injector, it worked like a champ.

The house is clean and I have a great back ache

Initially it did not seem too, but working with the adjustment it came together and started pushing the solution. I guess I should say - pulling the solution.

This was the first time I've worked with a turbo nozzel. It really helped get the siding clean. And yes, it is a great paint stripper. In any case it's now a permanent addition to my tool collection.

Thnak again for the help.

Glad it all worked out for you. By all means put that turbo on your truck and keep it there (on the truck) There is never a reason to use a turbo nozzle on siding. In fact you shouldn't have to go over 300 psi (yes 300 not 3000) The only time I ever use a rotating 0 degree is when I am removing latex paint from a concrete substrate that is going to be repainted. Did you look at your siding after it was dry? What was the siding made of?

Glad we could help you!
