Waterdrop King Tank Gravity Water Filter System – 2.25 Gallon Stainless Steel, With Stand

The King Tank is a gravity-fed stainless steel water filter that needs no electricity, no plumbing and no water pressure. Fill the upper chamber, let gravity do the work, and draw clean water from the spigot. For emergency preparedness that is the whole point – it keeps working during a flood, a snowstorm or a grid outage.

Why Choose the King Tank?

• No Power, No Plumbing: Sets up in minutes with no tools and no plumbing experience. Works when the utilities do not.
• 6-Stage Filtration: Coconut-shell activated carbon, PP cotton and post-carbon reduce chlorine, rust, sediment, soil, heavy metals and odor. Up to 98.95% chlorine reduction.
• 6,000-Gallon Filter Life: The pair of black carbon filters treats up to 6,000 gallons before replacement – the equivalent of tens of thousands of single-use bottles.
• 2.25-Gallon Stainless Chamber: Large enough for a household, light enough to carry. Suits the kitchen counter, an RV, a cabin or a bug-out location.
• Sight-Glass Spigot: A red floating ball shows the remaining water level without lifting the lid or upper chamber.
• Optional Fluoride Reduction: Choose the configuration with two additional white fluoride-reduction filters if that matters for your water.

Choosing Your Configuration

Both versions include the stand and the sight-glass spigot. The difference is the filter set: two black carbon filters, or two black carbon filters plus two white fluoride-reduction filters.

Frequently Asked Questions

• Q: Does it reduce TDS?
  A: No. Gravity carbon filtration reduces harmful contaminants while leaving beneficial dissolved minerals in place. If TDS reduction is your goal, a reverse osmosis system is the right tool.
• Q: Why is water left in the upper chamber after filtering?
  A: An inch or two remaining is normal. As the upper level drops there is less pressure pushing water through the elements, so the last of it filters slowly.
• Q: The initial flow rate seems slow. What should I check?
  A: Usually trapped air in the carbon elements. Submerge them in clean water – floating means air is still trapped, sinking means they are saturated. Let them sink fully, then reinstall.
• Q: Will it leak between the chambers?
  A: Only if you overfill. Empty the lower chamber before refilling the upper one and it will not overflow.

The King Tank is the system we recommend pairing with stored water – it is the one that still works when nothing else does.
