AutoPot FlexiTank Tap

The AutoPot FlexiTank Tap is the threaded fitting that connects an AutoPot FlexiTank reservoir to any standard AutoPot water distribution system. It ships with a washer and locking nut, installs through the lower port of any FlexiTank or FlexiTank Pro, and presents a Click-Fit outlet on the outside of the tank that accepts a range of 1/2″ hose connectors and tank adaptors. Every FlexiTank and FlexiTank Pro includes one tap as standard; this listing is the replacement or additional-unit option.

Why Choose the AutoPot FlexiTank Tap

The FlexiTank Tap is the single point of connection between an AutoPot flexible reservoir and the rest of a gravity-fed or pump-assisted growing system. Here is what makes this fitting worth understanding before you buy a spare or a replacement:

• Engineered for FlexiTank installation: The large threaded end is sized to pass cleanly through the main port in the lower body of any FlexiTank or FlexiTank Pro, so there is no cutting, drilling, or adapting required during assembly.
• Secure watertight seal: The included washer and locking nut create a tight, leak-resistant joint between the tap body and the tank wall. No additional sealant or plumber’s tape is required under normal assembly conditions.
• Click-Fit outlet keeps connections simple: The external outlet uses AutoPot’s Click-Fit standard, which accepts the 1/2″ Green Hose Connector, the 1/2″ Click Fit Tank Adaptor and Filter, and the 1/2″–1/4″ Click Fit Tank Adaptor and Filter — the same connectors used throughout the AutoPot ecosystem.
• Direct system compatibility: Because the outlet accepts standard AutoPot hose connectors and adaptors, plugging into an existing 1Pot, 1Pot XL, or multi-pot tray system requires no additional hardware beyond what AutoPot already sells as part of those kits.
• Replacement availability: All FlexiTank and FlexiTank Pro models ship with one tap as standard. This listing gives growers access to a spare without needing to purchase an entire tank kit again — useful in multi-tank setups or when a fitting is damaged.

Best Uses for the AutoPot FlexiTank Tap

This fitting is a purpose-specific component within the AutoPot watering ecosystem. The situations below represent the most common reasons a grower would purchase it separately:

• Replacing a damaged or lost tap: If the original tap shipped with a FlexiTank is cracked, stripped, or misplaced, this listing provides a direct replacement so the tank remains functional without purchasing a new reservoir.
• Building a second or expanded tank installation: Growers adding a second FlexiTank to an existing system — for example, to increase reservoir capacity for a larger tent or during a growing season extension — need a tap for any new tank that did not come with one pre-installed.
• Connecting a FlexiTank to a 1Pot or tray distribution line: In a standard AutoPot gravity-fed setup, the FlexiTank Tap is the handoff point between the reservoir and the supply hose leading to AutoPot 1Pot modules or tray systems. Growers who reconfigure their layout may need to re-plumb this connection.
• Adapting to different hose sizes: Because the Click-Fit outlet accepts both 1/2″ and 1/2″–1/4″ adaptors, the tap can serve as the transition point between a large-bore reservoir hose and a smaller-bore distribution line — depending on which adaptor and filter is attached to it.
• Spare parts inventory for commercial or multi-room operations: Facilities running multiple FlexiTank reservoirs across different grow rooms often keep one or two spare taps on hand to avoid downtime if a fitting fails mid-cycle.

AutoPot FlexiTank Tap vs Similar Tank Fittings

Tank outlet fittings for flexible reservoirs vary widely in design and compatibility. The AutoPot FlexiTank Tap is designed specifically for use within the AutoPot ecosystem and is not a universal bulkhead fitting. Here is how it compares to generic alternatives:

AutoPot FlexiTank Tap: Uses the AutoPot Click-Fit standard for the external outlet, which means it snaps directly into any AutoPot-branded hose connector or tank adaptor without tools. The tap body is sized to the specific port opening in the lower FlexiTank wall, and the included washer and nut are matched to that body. This keeps assembly fast and the fit predictable across all FlexiTank generations.

Generic bulkhead fittings: A standard bulkhead or tank outlet fitting from a plumbing or irrigation supplier uses NPT or BSP threads and typically requires a separate hose barb, reducer, or compression fitting to connect to an irrigation line. These fittings are more widely available and can work with many reservoir types, but they require the grower to source compatible connectors separately and verify that the thread size matches the tank port. In an AutoPot build, using a non-AutoPot outlet can create a mismatch with the Click-Fit hose connectors used elsewhere in the system.

For growers already in the AutoPot ecosystem, the FlexiTank Tap is the correct component. For those building a custom reservoir with non-AutoPot distribution hardware, a generic bulkhead fitting is likely a better fit — and they would need to verify that it seals correctly against the FlexiTank’s flexible wall material.

Compatibility

The FlexiTank Tap is designed and sold by Autopot Watering Systems USA as a component for use within the AutoPot product line. The following compatibility information is drawn from the canonical product description:

• Reservoir compatibility: Works with all FlexiTank and FlexiTank Pro models. The tap body is designed to fit the main port in the lower section of these tanks. It is not documented for use with non-AutoPot reservoirs.
• Hose connector compatibility (1/2″ outlet): The Click-Fit outlet accepts the standard AutoPot 1/2″ Green Hose Connector, which is the fitting used to run supply line from the reservoir to a distribution tee or directly to a pot system.
• Tank adaptor and filter compatibility: The outlet also accepts the AutoPot 1/2″ Click Fit Tank Adaptor and Filter, which incorporates an inline filter mesh to protect the distribution system from debris. If a smaller-bore line is in use, the 1/2″–1/4″ Click Fit Tank Adaptor and Filter connects to the same outlet and steps down to 1/4″ tubing.
• System compatibility: Once the tap is installed and a hose connector or adaptor is attached, the reservoir feeds into the AutoPot supply line network — compatible with 1Pot modules, 1Pot XL, Easy2Grow, and tray-based systems. Compatibility with air-pumped or pump-driven variants depends on the specific system configuration.

If you are using a separate inline filter ahead of the tap in a custom setup, confirm that the filter’s outlet thread or barb matches the Click-Fit or 1/2″ hose connector standard before purchasing.

Usage Guidelines

The FlexiTank Tap serves a single functional role: creating a watertight, removable outlet at the base of a FlexiTank reservoir. The guidelines below explain how to get the most reliable performance from this fitting.

• Install before filling the tank: The tap is easiest to fit when the FlexiTank is empty and laid flat. Attempting to install it in a partially filled tank makes it harder to align the washer and nut correctly from the inside.
• Hand-tighten, then snug: The washer and nut should be tightened until they compress firmly against the tank wall. Over-tightening can distort the flexible tank material and reduce the seal quality. Use only moderate hand force and a wrench for the final quarter-turn if needed.
• Position the tank on an elevated surface before connecting the hose: AutoPot systems are gravity-fed. The FlexiTank should be elevated above the growing area — typically on a shelf, stand, or raised platform — so that the tap outlet sits above the supply line and the AquaValve modules receiving the water.
• Attach the correct adaptor for your line size: If running 1/2″ supply hose, use the 1/2″ Green Hose Connector or 1/2″ Click Fit Adaptor and Filter. If stepping down to 1/4″ micro-tubing, use the 1/2″–1/4″ Click Fit Adaptor and Filter. Mixing connector sizes will not produce a secure Click-Fit engagement.
• Inspect the seal periodically: In humid grow environments, check the washer and nut connection once per growing cycle. If the nut has worked slightly loose due to vibration or repeated disconnection of the hose connector, snug it back up to maintain a watertight seal.

How to Install the AutoPot FlexiTank Tap

The installation procedure below is drawn from the canonical AutoPot product description for the FlexiTank Tap. It covers a standard initial installation into a FlexiTank or FlexiTank Pro.

1. Prepare the FlexiTank: Lay the empty FlexiTank flat on a clean surface. Locate the main port in the lower body of the tank — this is the pre-formed opening sized for the tap fitting. Confirm the port is clear of debris.
2. Insert the tap body: Orient the tap so that the large threaded end faces inward. Push the threaded end through the main port from the outside of the tank until the tap body seats flush against the exterior tank wall.
3. Fit the washer: Reach inside the tank (or flex the tank wall to access the interior side of the port) and slide the included washer over the threaded end. The washer should sit flat against the interior tank wall, surrounding the port opening.
4. Thread and tighten the nut: Thread the included nut onto the threaded end by hand. Tighten until the washer compresses evenly against the interior tank wall. Apply a final snug turn with a wrench if needed — do not over-tighten.
5. Verify the seal: Before filling the tank, apply light hand pressure to the tap body and confirm it does not rotate or shift in the port. The tap should be stationary with no visible gap between the body and the exterior tank wall.
6. Connect the hose fitting: Attach the appropriate Click-Fit connector to the outlet on the outside of the tank — either a 1/2″ Green Hose Connector, a 1/2″ Click Fit Tank Adaptor and Filter, or a 1/2″–1/4″ Click Fit Tank Adaptor and Filter depending on your distribution line size.
7. Fill and test: Fill the tank with a small amount of water (1–2 gallons) and inspect the tap area for leaks at both the tank wall seal and the hose connector. Address any drips before bringing the system to full capacity.
