The 3334L FatBoy Slimline Tank is the perfect solution when you need generous water storage in a narrow space. Built by securely joining two of our proven 1667L FatBoy round cylinders with brass joiners and silicone, this design combines the strength of a round tank with the convenience of a slimline footprint.
Cylindrical tanks naturally have superior structural integrity, as the water pressure is evenly distributed around the walls. That’s why tanks built in this way are far less prone to splitting than single-piece alternatives. In fact, Poly Water Tanks has NEVER had a tank split – setting us apart from our competitors.
Compact yet durable, this tank measures 975mm wide, 1950mm long, and 2250mm high, making it ideal for positioning down the side of your home, next to a shed, or in other narrow spaces. Despite its size, it weighs just 80kg when empty and is easy to handle during installation.
Each tank comes complete with:
-
A 400mm mosquito-proof inlet strainer
-
A 90mm PVC overflow with mosquito screen
-
A 25mm brass outlet and ball valve at the base
Manufactured from food-grade polyethylene, this slimline tank is safe for storing drinking water and equally suited for garden irrigation, greywater, or household use. It is fully certified to AS/NZS 4766:2020 and proudly WaterMark Certified, giving you confidence that it meets Australian standards (and can legally be installed by licensed plumbers).
Backed by our full 15-year warranty and proudly Australian-made, the 3334L FatBoy Slimline delivers the perfect balance of strength, durability, and peace of mind for your water storage needs.
