I'm about 1-1/2 hours northwest of Calgary, so Grand Centre would be about 6 hours northeast of me. For cleaning the breathers, all I've done is hose them off in the spring, that's it. I did have to take the cap off one of them to re attach the water line in the top heated breather tube. Otherwise, pretty trouble free. I'm pretty sure that the pump is DC voltage, so that black box is probably a voltage converter. It's probably cheaper to replace the whole breather instead of just the pump. I doubt you could find a replacement pump anyways .
