Connecting Multiple IBC Tote Tanks Together
A question that can arise among industries and DIY hobbyists alike is whether you can join two IBC tote tanks together. The answer is yes, it is possible to connect two or more IBCs together to increase storage capacity or to create a more complex system for distribution and use.
How to Connect Two IBC Tanks Together
There are several ways two IBC totes can be connected, but here are some general steps:
- Identify Connection Points: Decide where you want to connect the tanks. This could be at the top of the tank at the lid, the bottom at the drain valve, or at another custom location you add. The right connection points will depend on your needs, equipment, and setup.
- Choose the Right Fittings: You may need appropriate fittings to connect the IBCs to your plumbing or additional ones if more will be added. These could be camlock fittings such as quick connect couplers, S60x6 adapters, garden hose adapters, or other types of IBC tank fittings.
- Use Plumbing: Use plumbing of the right diameter to match your fittings and flow requirements. Flexible piping, such as hoses or pipes made of PEX material, can allow for easier connection and movement between the tanks. However, PVC pipe is most commonly used in connected IBC totes and distributing liquids from them.
- Join the Tanks: Connect the tanks using the chosen fittings and pipes. Ensure the connections are secure and properly installed to prevent leaks.
- Test the System: Once the IBCs are connected, test the system by filling the totes with water and checking for any leaks or issues.

Things to Consider When Connecting IBC Tanks
When connecting IBC tanks together, there are a few points to consider:
- Water Quality: If you connect your tanks at the bottom for filling, any dirty water going into the multi-tank setup will be shared with all the tanks.
- Safety: Ensure IBCs are secure and stable when connected to prevent a fall or accident that can damage your entire setup. This is particularly important if you are stacking the tanks.
- Regulations: Depending on your regional location and the intended cargo use of the tanks, there may be regulations or guidelines that you need to follow when connecting IBC tanks. This typically only applies to chemicals.
- Flow Control: To ensure even filling or draining when multiple IBC tanks are connected, it might be necessary to incorporate some form of flow control, such as additional ball valves, check valves, or a pump.
- Preventing Contamination: If what the IBC is being used to store is sensitive to contamination, consider using non-return valves or check valves to prevent backflow between the connected tanks.
- Maintenance: Regular inspection and maintenance of the connections are necessary to ensure leaks do not develop and the long-term functionality of the combined tanks.
In summary, it is possible to connect two and more IBC totes together and therefore increase the total storage capacity or create a more complex system to provide whatever liquids you are you keeping in your IBCs.
