CPS 2500 nozzle selector broke on my first time using it.. Any idea on how to repair it?

Post by Sozo_Mizakii » Thu Apr 30, 2020 9:31 am

Greetings, I am Sozo and I'm hoping to get some help with a blaster I just acquired. Anyway, I recently acquired a cps 2500 on ebay for a steal and was elated to get it.

So, it does pressurise and shoot, the problem is that when I did pull the trigger, the nozzle selector flew clean off. It broke right where the screw had connects to the nozzle. Other than that, the gun seems to work fine. I'll be getting pictures for you guys soon.

Thanks guys. I really want to get it back up and running.

Welcome to WWN!

Post the photos once you have them. This should be repairable. What tools do you have available? A drill might be useful depending on how the nozzle assembly broke.

Thanks Ben, I really do appreciate your willingness to help with this issue. It was disheartening to say the least to see it fly and a bunch of stream come out and a nozzle flying with it XD. Here is the link of all the parts. As for tools, I've have next to none, but I can get some. My girlfriend's uncle should have a drillpress and let me use them.

I've attached your photos here as external images tend to break after time and we want to preserve as much repair knowledge as possible.

Repairing this will require a fair amount of work but is possible. Personally, I would find a broken CPS 2500 and swap out the entire front part of the valve with the flow straighteners. That would be the easiest repair. Without that, I would simply attach a PVC threaded adapter to use screw-on nozzles.

If you're set on repairing it back to the original functionality without a broken CPS 2500 to cannibalize, here are some things to consider:

There should be two of the orange bumpers. See the image below. Did you lose the other one when it broke? This part is probably necessary to make sure that the nozzle selector seals properly.

I also assume that there was an O-ring in the slot around the water opening. You should be able to find a replacement in a hardware store, or, failing that, online.

Once you have all the components, the main task is going to be basically attaching the nozzle selector to the blaster. You'll have to make a new "nub" for the screw to attach to. It might be easier to not use the existing screw and substitute your own. This might require drilling a larger hole for the new screw to go through.

It would be better to attach the new nub at multiple places with small screws than to try an adhesive. Something like this might work because it has three prongs: https://www.mcmaster.com/94122a100

But it might not be possible to use screws to attach the nub if the inside of the front end of the blaster needs to be sealed. I think it's probably okay to screw through the top part between the two openings but I'm not sure on the other sides. Might be safer to instead pick a surface-mount nut with only one attachment point and use the spot between the two openings at the top.

McMaster-Carr has a wide variety of surface-mount nuts available that you could look through to see if any fit the dimensions: https://www.mcmaster.com/surface-mount-nuts

You'll probably have to try a few things before figuring out something that works. Anyway, I don't mean to discourage you as this should be repairable but it's going to take some machining skills and patience.

Apologies for necro-posting my own thread. School and work have taken my time from me and so, I've been trying to source a blaster like Ben suggested. I was successful in finding one and should be able to make a guide (this may be redundant but it's for others who don't have any skill in machining). When the blaster comes, I'll be sure to take images and a guide relating to it
Mods, I apologise for this. Just giving an update
