FlexiTank with Tap — Collapsible Water Storage That Actually Works
Best for: Growers who need portable, space-saving nutrient storage without sacrificing reliability
Our thoughts
FlexiTanks have earned serious trust from growers for good reason — they do the job exactly as they should, but with the convenience factor that rigid tanks just can't match. Once you've used one, there's no going back. Smart piece of kit at a sensible price.
The FlexiTank with Tap is a collapsible water and nutrient storage reservoir built for growers who want reliability without the bulk. Unlike rigid tanks, it collapses flat when empty, stores away easily, and requires zero tools to assemble. The integrated tap with quick-fit connector means you're up and running in minutes, not hours. Built from heavy-duty PVC, it's tough enough for continuous use but flexible enough to fit into spaces where standard reservoirs simply won't go.
How it compares
This is the portable, practical alternative to rigid tank systems.
- Collapses for storage and transport — rigid tanks don't
- Tool-free assembly in under five minutes
- Universal compatibility with AutoPot, IWS, Flood & Drain, and most hydroponic systems
- Pre-fitted tap with click-fit connector included as standard
- Cost-effective compared to equivalent rigid plastic reservoirs
- Lighter shipping weight than fixed tanks, so less to move around your space
In plain terms: you get the functionality of a proper water tank without the storage headache or the price premium.
Usage guidance
Assembly
Unroll the fabric tank, slot the support legs into the side wall channels, fit the tap through the lower port from inside, add the seal, and screw the lock-nut tight. The tap's snap-fit connection means you can plug in and unplug hosepipe connectors in seconds. No specialist tools needed.
System integration
The tap outlet accepts standard 1/2" connectors for garden hose, Click Fit Tank Adapters, and Filter combinations. Three additional inlet/outlet points with grommets give you flexibility for whatever pipework setup you're running. Compatible with standard 13mm internal diameter IWS pipework, so it plays nice with virtually any system type.
Monitoring and maintenance
Clear fill line markings on the exterior let you see exactly how much solution you've got without guessing. Empty it between cycles, store it flat, and you've got a tank that'll keep working properly for years.
Temperature control
If you opt for a FlexiTank Pro model with reflective white skin, the light-blocking layer helps prevent nutrient temperatures from climbing. That matters — when solution temperature creeps above 21°C, dissolved oxygen levels drop, and that's when plants become vulnerable to root problems. The reflective skin buys you peace of mind, especially in summer.

Our take
The FlexiTank with Tap is the kind of kit that solves a real problem — storage space, transport, assembly faff — without compromising on function. It's built tough, works reliably, and plays nicely with pretty much any hydroponic system you're running. The tap's quick-fit connector means you're not wrestling with fittings every time you want to connect or disconnect your lines.
If you've been putting up with rigid tanks because you thought that's what you had to do, worth picking up while stock lasts. Does exactly what it should, day in, day out, and gives you your space back when you're not growing.
