Dud Injectors

I may disconnect my high pressure hose from the reel and just bypass the reel for a while to see if I get better results with the Hi-Draw injectors. I use Titan reels (less than a year old) with Super Swivels, 12 GPM gun, 2.1 (injector) orifice with 200 feet of high pressure hose, and I always flush 5 gallons of water through the injector at the end of the job. I use a filter before and after my 225 gallon water tank. It seems that I'm doing all the right things but still having bad luck with the Hi-Draw injectors.

Actually, I've been through 3 or 4 (12 GPM) guns and had an unloader go bad (within 8 months) since I started using my 8 GPM machine in May 2013. I put a Zeromatic unloader on my machine hoping that guns, hoses, and injectors would last longer. I've been thinking that the 8 GPM machine sure is harder on guns, hoses, unloaders, and injectors, than the 4 GPM machine. When I used my 4 GPM machine exclusively injectors lasted years, I never had an unloader go bad, and guns lasted a long time. The big difference was that I bypassed the reel with my high pressure hose. Maybe I'll have better luck bypassing the reel with my 8 GPM machine.

Surface cleaner swivels last longer too.

I changed things around last year, I have a few of hose reels where I don't use the swivel, they are just storage but I do have one reel where I do use the hose reel.

I have long jumpers from each machine so I can use any of the hose reels on either machine.

On a large project I was switching out hoses checking to see if I got any different results with the hose reel with the swivel and the reels without using the swivel and the results were about the same. One reel has 150' of 3/8" hose with using the swivel, the other reels are 100' of 3/8" without the swivel, 165' of 1/2" hose without a swivel and 200' of 3/8" hose without the swivel, it all worked good for house washing with very bad green algae and black mold.

One of my Super Suds Suckers went bad so I used one of the Hi Draw injectors (grabbed the wrong one by mistake) and used it with the 150' hose reel with swivel and we connected the 100' hose onto the end of the 150' hose so we had 250' of pressure hose working and the Hi Draw was working on this end of the project. Later we switched over to using the 200' of hose with the extra 100' to reach further and the Hi Draw still pulled the soap and worked good.

With this same hose I put my other spare super suds sucker on and it did better as for cleaning speed and strength of detergents on this project so I got lucky with this Hi Draw injector but I know sooner or later it will fail, probably sooner than later, but I have my daily use super suds sucker injector there so I am ok.
 
I just went out to the garage and disconnected my high pressure hose from the Titan hose reel. The MPT fitting on the end of the hose as well as some of the threading on the outside of the fitting was completely black. I've always had my injector placed just before the swivel on the hose reel and always disconnect the injector after each job. When disconnecting the injector I've seen the dark colored water spill out of the swivel on the hose reel. So it seems that the hose reel may be corroding inside and leaving a black residue in the water trapped inside the reel. Maybe the black residue is backing up into the injector while it's connected in the high pressure line and possibly causing injectors to go bad.

It's all mystery but I think bypassing the hose reel will help the situation by eliminating the black residue. I'm thinking I'll just go back to using the high pressure hose reel for storage only.
I also think I'll start running the machine without the gun in order to flush out the high pressure hose at least once a week if not more often.
 
I have the plug and coupler on the injector so I can remove them when not needed, I don't keep the injector inline all the time as it does restrict flow when running the surface cleaners.

Adding the injector or removing it with the plug and coupler on it makes it fast to change out.

Even on the hose reel that I use the swivel on, there is a small jumper hose from the reel where it plugs into the jumper from the pressure washer so the injector just plugs in between those jumper hoses and when I am running the surface cleaner, no injector there. Outlet of the jumper from the pressure washer is a plug, inlet of injector is a coupler, outlet of injector is a plug, inlet of jumper hose to the hose reel with swivel is coupler, outlet of hose on reel is plug so you can have everything setup the same and with or without the injector everything connects easily.

Hope this helps.

Chris, I use quick connect couplers with my injectors too. The only place I do not use quick connect couplers is where the 100 foot high pressure hose is connected to the hose reel outlet. I just disconnected my 100 foot hose from the hose reel outlet and will be bypassing the reel altogether from now on.

Rick get a stainless manifold when that one in the reel goes bad it helps eliminate that black goo.

Great advice Hal. My Titan reels are stainless except for the manifold and of course the PVC center part. The manifold is just regular old steel and is making a mess with all of the corrosive bleach running through it. I always reel off all of the hose and also disconnect the injector when not in use so bypassing the hose reel will not be a big deal as far as setting up goes. Thanks for the good advice!
