Frequently Asked Questions
No. Big Orange does not filter the waste in your tank, only the air that is vented out of the tank due to flushing, boat movement, or tank expansion. Just be sure to not overfill your tank. If you do, you will need to clean out the filter and replace the carbon and filter screens.
Possibly. While the bypass valve in Big Orange is highly reliable, some pump out facilities are very aggressive.
When measuring for the new section of vent line needed to connect the outlet of the holding tank to the inlet of Big Orange, be sure to allow for a generous loop that rises above the tank. This should prevent any splashing of waste from working it's way to Big Orange. Make sure to keep an eye on your tank level, and do not overfill your tank.
The only way to be 100% sure on whether or not waste has entered your Big Orange filter is to simply remove the cartridge and inspect the openings for waste.
No, the bypass valve is automatic. You never need to activate the bypass valve, it is operated by the difference in pressure between the tank and the vent line. Positive pressure keeps the valve closed and negative pressure (like during pump out) opens the valve.
Big Orange is proud to be designed and manufactured in Canada.
With proper maintenance, the Big Orange Original filter will last for years. The filter medium (carbon) that removes the odour should last at least an entire season, depending on use and conditions.
If your tank overfills and waste gets into the filter you will need to clean out the filter and replace the carbon and filter screens. Otherwise, the Big Orange filters are low-maintenance!

Went back and had my oldest daughter test the flushing and… well… nothing… Sweet, blessed, nothing… No scent, no whiff, no indication of what has taken place in the head. Awesome.
