Frequently Asked Questions
Q: What is an external septic tank for an RV?
A: An external septic tank for an RV, often called a tote tank or portable waste tank, is a separate container used to store black water (from the toilet) or gray water (from sinks and showers) in addition to your RV’s onboard tanks. They are useful for extending your stay without needing to move the RV to a dump station.
Q: How often should I empty my RV’s external septic tank?
A: You should empty your external septic tank when the level indicator shows it is full, or before it reaches capacity to prevent overfilling and potential issues. For smaller portable toilets, this might be after a few uses; for larger tote tanks, it could be after several days of use.
Q: Are external septic tanks safe for the environment?
A: Yes, when used properly. External septic tanks are designed to hold waste until it can be properly disposed of at an approved dump station. It is crucial to always dispose of the waste at designated facilities and never dump it onto the ground or into storm drains.
Q: What is the difference between a black water tote tank and a gray water tote tank?
A: While some RVers use a single tote tank for both, it’s generally recommended to keep black water and gray water separate. A black water tote tank is specifically for toilet waste, while a gray water tote tank is for sink and shower water. This separation helps maintain hygiene and can simplify the disposal process, as gray water is generally less hazardous.
Q: Can I use RV septic tank treatments in an external tote tank?
A: Yes, most RV septic tank treatments, like Camco TST MAX Drop-Ins, are designed to be used in both onboard RV tanks and portable tote tanks to help control odors and break down waste.
Having the right external septic tank for your RV can significantly improve your travel experience, offering greater flexibility and peace of mind. Whether you prioritize odor control, capacity, or portability, there’s a solution out there for you. Explore these options, consider your specific needs, and get ready for more comfortable and convenient RV adventures!
