Downstreaming w/ bleach

I want to downstream SH through my machine, an Ex-Cell 3600, but in reading the user manual online it said to never put "bleach or other corrosive chemicals" through the chem injector.

My question is, what is that supposed to mean? I know plenty of you all on here downstream SH all day with no problem.

Thanks,
David
 
That' so you cant return for warranty and try to get a new one, OR that model has an injector that will run the chems through the pump. If it does, then Ted is right, X jet is a good option, or just get an injector you can put "downstream" of the pump

Funny thing is, the injector appears to already be downstream of the pump. It is past the pump right before the hose.
 
Then you are fine. They will never know if you are injecting chemical or not
 
I'm bad about forgetting to flush my injector so I'm not one to do as I do but I would definitely flush that injector with fresh water when you are done. I've had a small pressure washer with one of those built on injectors and they have a lot more internal parts that will corrode for some reason. They aren't built like the ones we use.
 
I always try to run water through the injector when rinsing the house and that has helped my injector last over a year or longer now.

I downstream soap to 1/4 to 1/2 of the house then rinse the house (move chemical hose from soap to water container) then keep on going until the house is done.

As for your injector, they are just parts that you use then replace most of the time, if your injector is past the pump and not part of the pump itself, I would not worry about it.

Post some pictures of it.
 
I looked up the unit. Looked up the owners manual. http://www.excellpressurewasher.com/documents/pdf/D28001-E.pdf from the instructions.."Chemical Hose: Feeds cleaning agents into the pump to mix with the pressurized water. See How To Apply Chemicals/Cleaning Solvents in Operation section of this manual."

A lot of residential machines do this, not recommend to use any any bleach through the chemical pick up hose. Our machines that are commercial and industrial have a separate injector that is after the pump and none of the cleaning agents flow through the machine. You will need an x-jet.

Also be careful with this machine, it is low water flow but very high pressure. The pressure isn't what does the cleaning so plan on taking your time on most house cleaning jobs, this will take a bit of time. Need to to get different spray tips to lower your pressure. Most vinyl is done under 1000 psi and brick a little bit more, wood is somewhere very low. If you do searches on here and read all the residential posts you will have a good foundation on how to proceed.
 
The unit you have there is a downstream injector. The main reason they do not want those chemicals run through it is if not diluted or rinsed they can wear out the injector in a few hours use and people will be calling and complaining. The injector on there can handle it but will wear out eventually. Tough to tell from the picture but it may be integrated as part of the unloader so when it wears out you may not be able to rebuild it in a cost effective manner. Don't worry though you can disable it and put another removable one after it and still use the unit just fine. If you take a pic of the other side I can tell you for sure which will work.

Hey Paul! Got the tracking info. Thanks. Great service, follow through and unsolicited punctual updates!

From the model number and manual, looks like his machine is 3600@4 GPM which I believe calls for the 2.1 injector
 
Thanks for all the info, guys. I actually already have a downstream kit from Bob at PT, which effectively lowers the pressure to about 800 PSI, so I'm not too concerned about the high pressure machine.

Here is a picture of the other side:

Will this injector continue to work if I just rinse with clean water every time? Also, can I use the same bucket again to rinse, just with clean water? This is what I've been doing and it seems to work fine.
 
Your attachments don't open.

Injectors can last a day to a year, many different things will affect how long they last, try to keep a few of them with you all the time as you don't know when they will stop working. I tried the rebuild kits and did not have much luck with them the past few years so I quit buying the kits, just replace the injector when it stops working.

The nozzles will last you a long time, just rinse them out when the job is done and that will help them last a bit longer.

I would also keep spare nozzles as sometimes the nozzle holder gets misplaced or lost, even when left on the gun.

Try to have spares of everything so if something happens, breaks or wears out on a job, you can be up and running again in a little bit of time, hose, injectors, nozzles, gun, wand, swivel for the hose reel and hose, swivel for the surface cleaner or cartridge (if it is the new whisper wash swivel), injector chemical hose, etc.......
