Do you guys have a video showing the removal of the DS injector? I have the same pump and I am looking to correctly install a DS injector bypass assembly. But I do not want to remove any necessary parts from the pump that would mess up the unloader...I’ve removed the DS injector and I notice a separate spring and orifice inside...

This is direct chemical injection? The way you show the chemicals go through the pump? If so isn't this hard on the pump and down stream injection would be better? I am trying to learn, thanks!

BlackHawkPSU Hello and great question!The chemical injector on this pump is 1. built into the unloading/pressure regulator and 2. only injects chemical after the water leaves the pump. The nipple you see there which the chemical is sucked through is just before the OUTLET hose connection which means the water there is only flowing out of the pump so the chemical never actually passes through the pump. It only will flow out through the hose and gun. If your pump doesn't have a built-in injector and it just quick connects on and off you can connect either right at the OUTLET(where you water exits the pump) or in between the hose and gun(down stream).

JN Equipment Thank you, this is very helpful! I just purchased a pressure washer (the Maxus MX5433) which has the CAT 66DX so knowing this has downstream built in is great to hear... I didn't realize that. I just tried it out today and the pressure regulator (unloader?) will not turn. I read another person having a hard time figuring that out and not being able to get it to turn as well. That person even spoke to CAT directly and still wasn't able to get it turned. Is there a trick to it? How good would you say this particular CAT pump is? Any tips are appreciated as this is my first real pressure washer. Thanks again a great video!

+BlackHawkPSU CAT pumps are a very reliable brand. When you remove the black plastic cap on the unloader you should see a lockscrew holding a large nut in place. That is the only thing that could be stopping you. Try backing out that set screw and lowering that nut. Be careful not to over pressurize your pump though(the lower you turn it the more pressure).

Correct me if i am wrong but dosen't chemical injector result in about a 200 psi pressure loss when you are not using it ? Would rather have the chemical injector be a separate piece connected when needed with quick connects.

Theoretically (oh boy) you shouldn't lose any pressure when it's not in use as the ball within the assembly should stop that from happening. It is definitely possible to lose pressure if your o-ring, sping or ball are worn down or not seating correctly. I personally do not like the "built in" injectors and also prefer the quick connect versions that you mentioned since they are easier to repair, remove or replace.

Is it better if you had a by pass set were the low pressure would be connected to higher pressure or reservoir tank .

I know this video is old but he got the thermal valve mixed up with the chemical injector lol that brass piece pointing UPWARDS is the thermal relief valve not Chemical Injector

no, we didn't mix that up. The black & brass piece is a "thermal relieve valve" the chemical injector on this pump is actually molded directly into the unloader where the water exits the pump which can be seen around 5:30.

is the chemical injector necessary, can it just be eliminated, I would not use it.

+Angel Morales, It can be eliminated if you know your not going to use it.

What does the therm o adapter do?
@Spraywell

The thermal adapter is very VERY similar to a thermostat in a car. What it does is once the water in the pump gets hot enough, it'll open the valve and release the hot water out of the pump thus allowing new cool water from your water supply(hose or tank) to enter to pump. That part is the last ditch effort to save the pump seals from melting due to extremely hot water. The best way to avoid water in your pump getting to hot is do not allow your pump to stay in "bypass mode" for longer than 1 minute.
