Enduramaxx 300L Slimline Potable Tank review
The buy-once reserve — the only WRAS/DWI potable-rated tank here, UK-made, 10-year warranty.
By Tom Calder
If you want a fixed water reserve done properly, this is the grown-up option: a UK-manufactured 300-litre tank actually approved for potable storage (WRAS and DWI), with a 10-year warranty and a 600mm round footprint that tucks into a garage corner. That approval is the difference between 'food-grade plastic' and 'certified for drinking water systems'. Full it's around 300kg, so it wants level, load-bearing concrete — a garage or slab, never decking — and stored water still deserves periodic rotation.
