Flexible Rectangular Water Tank - 55L Grey 31321

Flexible Rectangular Water Tank - 55L (Model 31321) from Nuova Rade is the ultimate potable water solution for boats and caravans—combining generous capacity with a flexible, space-saving design.

Why this tank stands out:

• 55 litres of drinking-water-safe storage in a compact, rectangular form that fits awkward corners and under seats on boats or caravans.
• Made from non-toxic PVC, it’s designed to be safe for potable water and daily use on marine and mobile setups.
• Flexible yet sturdy: the heavy-lapped seams are reinforced with a “doubler” for extra strength, so you can rely on it during bumpy trips.
• Includes two adjustable elbow fittings (40 mm and 12 mm) connected to skin fittings welded into the tank, making installation quick and leak-free.
• Outlet tail direction is adjustable, giving you installation flexibility in tight spaces and helping you route lines precisely where you need them.
• Lightweight and easy to store when not in use—rolls flat, freeing up cabin or locker space.

Ideal for:

• Boat owners who need a potable water reserve that won’t clutter cockpit or cabin space.
• Caravan travelers who want a reliable, portable water supply that’s easy to refill and transport.
• Temporary or auxiliary water storage during maintenance or offshore trips, where space is at a premium.

Practical tips:

• Rinse the tank before first use to remove any manufacturing residues, then flush with drinking water until you smell and taste nothing unusual.
• Avoid overfilling to maintain flexibility and prolong seam life; this tank relies on being full to maintain shape and stability while in use.
• Keep the tank away from direct sunlight when stored empty to minimize material fatigue over time.
