Ok, bear with me…I did search this issue and found that some say it so normal to hear a loud whining sound when the chem injector is being used on an 8gpm. I’m using a high draw 3-5gpm injector from pressuretek. Can anyone else chime in and verify whether this is normal? Is there a better alternative? Machine is brand new and just want to make sure I’m not damaging anything… ---

My reels make a squealing sound. The only whining is me when I’m fighting with my hose. ---

Normal. You can try placing the injector further from the reel swivel but I doubt it will do much. I honestly don’t even notice the squeal anymore. Probably because I’m not swapping from soap to rinse by hand anymore. Click that Schertzbox remote and away we go! ---

Just put the order for mine in the other day… I’ve wanted it for so long and everytime I was far away from the trailer I’d imagine clicking that remote around my neck and that was enough for me to break down and buy the box ---

Awesome Steve! If possible a parts list would be incredible. I don’t remember seeing that valve in here before? In any case thank you! ---

Mine looks kinda like that, but I use a rotary valve and my strobe is on top if the trailer. If I may, consider using vacuum hose on the injector side, my reinforced hose collapsed twice so I switched. ---

It’s a solenoid valve instead of an actuator valve. It uses a magnet at the top to open the valve when energized, otherwise it’s normally closed by a spring. Some people prefer the actuator valve because it won’t get as hot and doesn’t use as much battery power as the solenoid. I chose to use the less expensive solenoid valve so I could build in redundancy. I actually ordered 2 valves and put quick a quick connector on the wires. I mounted the valve with velcro and in the event of a valve failure I can pop in a new valve in a few minutes, and I remain working while I send in the bad one for warranty. If your $220 actuator valve goes out, you’re screwed until you get a repair or replacement. > [@dcbrock](#): > > If I may, consider using vacuum hose on the injector side, my reinforced hose collapsed twice so I switched. I’ll keep an eye on that. That hose is the off the downstream injector that’s been on there for a couple of years without any problems. Was it heat that collapsed the hose? I can’t imagine the injector producing that much vacuum. ---

I used those valves when I was making my own remotes and still have a half dozen or so. They lasted about a month or so, which wasn’t bad for the price. The downside is, it only stops the soap, it doesn’t switch to water like a three way does. ---

If you got two of the valves, one normally open and one normally closed, you could wire them in parallel with the remote and plumb them both into a tee before the injector. When the bleach solenoid closes, the water solenoid would open, rinsing the injector and giving you back that little bit of lost flow.
