Trigger Systems Platinum Sump Stripped Gear

My two week old Trigger Systems Platinum Sump just stripped two teeth off the filter roll take up sprocket! The thing has been really making groaning sounds since I got it every time it spools up some filter and I have been very concerned as it uses plastic gears. The supply roll was free to spin and the filter was correctly aligned in the filter path. I was excited about this thing as it filters well but if the fix is just another brittle plastic gear then I feel like I cannot rely on it.
Trigger Systems does not list any customer support or contact information at all on its website. Fortunately I got a contact number from a previous post. Going to call them Monday and see what they intend to do about it.

Stripped Gear


Machined surface on the other side of the take up roll is pretty rough. Definitely not a nice smooth surface and it has allot of tension on it. Lots of rolling resistance and with 10" wide roll there is allot of tension required to pull filter through.

If it were me & they sent another plastic one I would think about one made by a printer.
Perhaps they have a way with tougher materials.
Trace the outline before installation.
Agreed machining leaves something to be desired.
Shame because I was thinking about one.
Keep us up to date please.

I have a 3d printer and am proficient at Inventor so I was considering making a gear but am really hoping that Trigger Systems comes through on this. I really doubt that even a carbon fiber reinforced nylon filament like NylonX would hold up for long. I imagine this could be a big seller but if it proves to be unreliable it's dead in the water. I suppose something has to be the weak link in the gear train and having the spur gear break is better than the gear box or take up roller gear. I think there is too much slop and tensions and friction are too high for the mechanism as is. I suspect that I am not going to be the only one with this issue.

So Trigger Systems website has absolutely no customer support information and the number I got for Trigger Systems LLC in Texas (214)280-5178 does not answer calls or text. On their "about" page they say they pride themselves on their customer service.
Does anyone have any idea on how to get ahold of somebody there?

Might have to go through where you bought it.

Yea, I have contacted AquaCave and their customer support is helping me. They picked up on second ring. They seem to have top notch customer service.

It is indeed an Acrylic Gear. That worries me allot as I dont see acrylic as being good for a wear surface long term and it is brittle. Trigger Sys is sending a new gear and take up spool and said that they have had some small number of manufacturing defects. They claim they have run the sumps with those gears for 2 years of testing and never had a gear break. The sumps is a beauty and I hope this turns out to be a rare occurrence. I am wondering about using a bit of food grade silicone grease on the rotating surfaces.

Definitely keeping an eye on how this plays out. Was super excited when they released these sumps. Very curious to see how long that replament acrylic gear lasts.

Got a replacement roller and gear and it is running smoothly. I am not thrilled about gear but guess it will work. However now the motor keeps going no matter what I do with float switches. Uhg, don't know if that was caused by gear jamming up and breaking or if motor running was to blame for broken gear. Frustrating.

As I suspected there is a FET transistor used as a low side switch to drive the motor and when those fail they typically fail shorted as this one has. Not sure what the part number is but it is in a SOT23 surface mount package and if it is like a 2n7002 then it can only handle 100mA of current. Seems pretty weak for driving a motor that could draw 300mA when stalled and is very likely why it failed. Overall the "electronics" are very cheap. No microcontroller and it is basically the FET, two leds, a flyback diode and a few resistors. Probably less than $2 worth of parts. Not impressed. Granted it doesn't have to do much other than switch on and off the motor based on float switches but for almost $1000 I would have expected better. Clearly they are shooting for big profits over quality. The wall wart the thing comes with is tiny and only rated to 230mA. Likely straining to run that motor. Again as cheap as possible. Motor and gearbox are very low end junk like you would find in a toy car. The more I look at this thing the more issues I notice. Very disappointed.

Screw it I'm going to run the motor off an aux DC port on my tank controller and let it monitor the float switches. That is better anyway as I can then see the status of the filter roll remotely. Can also use the data to track how much filter roll has been used, how dirty the water is by how often it runs and probably a few other things that may come to mind. I modeled the gear in Inventor and will print one out if it fails again.

At least you are savy enough to troubleshoot this on your own.
Most including myself would just be COMPLETELY LOST.

It definately comes in handy to be electronically savey. I was going to see what Trigger Systems was going to do about it before diving in but my curiosity got the better of me. I have it hooked up to my Robotank controller and its working great. Completely bypassed the interface board and connected straight to the motor and float switches.

I imagine that my posting of this and detailed negative reviews are breaking their shoes.

Direct contact if @ all possible ---
I will not pursue anything with them until this is resolved.
As will,a lot of others.
