I have to say I am really impressed with the Big Orange. it works great and zero smell after a flush. Well worth the time and money!
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.
I also added the Big Orange a few weeks ago ! Awesome product. The installation was fast and easy and the after flush smell is totally gone !

Frequently Asked Questions
Big Orange is proud to be designed and manufactured in Canada.
Big Orange filter assembly will last for years. The filter medium (carbon) that removes the odour should last an entire season depending on use and conditions. However, if your tank overfills and waste gets into Big Orange you will need to clean out the filter and replace the carbon and filter screens.
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 will act like a baffle and should prevent any splashing of waste from working it's way to Big Orange. Also keep an eye on your tank level, do not overfill your tank.
The only way to be sure if waste has entered Big Orange is to simply remove the cartridge and inspect the openings for waste.
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. Be sure to not overfill your tank and get waste inside of Big Orange. If this happens you will need to clean out the housing and replace the carbon and filter screens.
Possibly. The by pass valve in Big Orange only eliminates the restriction created by installing an inline filter. Some pump out facilities are very aggresive and will collapse the tank even if you don't have a filter installed. The tanks are made of soft plastic that can withstand some collapse but it is just a matter of time before a collapsed tank will crack.
No, the by pass valve is automatic. You never need to activate the by pass 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.
