RichNJ Posted February 29 Share Posted February 29 My three year old FZ7 FORZA is starting to rattle. I’ve cleaned the impeller and that worked for a while but it’s rattling. Do impellers need to be re-lubricated? Link to comment Share on other sites More sharing options...

But I found the part at least. I submitted a question to their help desk Link to comment Share on other sites More sharing options...

If it was my filter, replacing the impeller would be my first attempt to fix the rattle. Its the only moving part. Its what is going to make noise, and it is what is going to wear. My guess would be the tolerance between the shaft and the impeller itself is looser than when new…. But, I have guessed wrong on things before…. 1 Link to comment Share on other sites More sharing options...

I’ve cleaned the impeller and that worked for a while but it’s rattling. Do impellers need to be re-lubricated? Yes, but it's likely not the lube that is an issue. Over time the shaft itself will wear. That is why the impeller itself is the most often replaced item and it is a standard part for most filters. Same thing with o-rings. You can visually see this on the shaft itself. The other thing that can happen is things just aren't aligned correctly due to debris. Marina, fluval, and some other people sell impeller cleaning kits for this task. Something like a bottle brush for a straw works as well. In terms of lube, you want to use 100% food grade silicone grease. The one I use is from a dive shop and available on amazon. 2 1 Link to comment Share on other sites More sharing options...
RichNJ Posted February 29 Author Share Posted February 29 (edited) what is the purpose of adding lubricant to the o-ring on the lid of the filter? @nabokovfan87 @Pepere Edited February 29 by RichNJ 1 Link to comment Share on other sites More sharing options...
Pepere Posted February 29 Share Posted February 29 Less friction and abrasion as you fit the lid to the canister hence longer leak free life. 3 Link to comment Share on other sites More sharing options...

It also keeps if from drying out and becoming brittle, cracking. Edited February 29 by nabokovfan87 1 Link to comment Share on other sites More sharing options...
Pepere Posted February 29 Share Posted February 29 I know Fluval recommends new o rings at a year. Other brands might be different. I wonder if the reputation for being prone to leaking is due to not lubing and changing o rings as recommended. Link to comment Share on other sites More sharing options...

It also helps prevent rattling from a loose fit. That's why high end car detail shops will lubricate the seals on your car when they clean them. Keeps them moist and sealing good no rattle from the door and no air noises. Same for our filter. 1 Link to comment Share on other sites More sharing options...
