Curated by The Field Editor · Updated June 2026
Built for owners of remote properties who need reliable, electricity-free water pressure through elevation rather than pumps. Not for urban households or high-flow irrigation—this shop focuses on simplified residential utility and drinking water safety.
Curator's pick: Big Berkey Gravity-Fed Water Filter
The stainless steel housing resists the corrosion and UV degradation that typical plastic filters face in remote environments, making it a sustainable choice for long-term stationery use. Its mechanical filtration process operates independently of water pressure, ensuring a consistent supply of potable water even when the primary storage tank is low.
⚠ Worth knowing: Gravity-fed setups are highly sensitive to head pressure; placing the storage tank less than 10 feet above the tap will result in a flow rate too slow for standard appliances. This configuration requires specific height differentials to function effectively without a supplemental booster pump.

In this shop: This sediment filter is an important first step in cleaning water for a Gravity Fed Water System for Off Grid Living, protecting the main filter.
This system provides complete water independence, allowing for collection, storage, and purification without any reliance on an electrical grid.
The combination of a storage tank and gravity filter ensures a continuous supply of safe drinking water even during power outages or in remote locations.
Utilizing natural gravitational force minimizes operational costs and offers a sustainable, environmentally friendly method for water management.
What to know
Initial setup may require some manual effort for elevation and connection, and ongoing maintenance involves periodic cleaning of components.
The system's capacity is limited by the tank size and filtration rate, which may necessitate careful water usage planning for larger households or extended periods.
How to use this together
1
Establish Water Collection & Pre-Filter
First, identify your water source (e.g., rainwater catchment) and place the '50 Gallon Horizontal Water Storage Tank' to collect it. Install the 'Inline Sediment Water Filter' directly before the tank to remove larger debris, protecting your main storage and prolonging the life of finer filters. This order ensures cleaner water enters your primary storage.
2
Automate Tank Filling
If you have a continuous or intermittent source, install the 'Float Valve for Water Tanks' into your 50 Gallon Horizontal Water Storage Tank. This valve will automatically open to allow water in when the tank level drops and close when it's full, preventing overfilling and ensuring a consistent supply without manual oversight.
3
Purify Drinking Water
Set up your 'Big Berkey Gravity-Fed Water Filter' at an accessible location, ensuring it's higher than your point of use for gravity to work effectively. Fill the upper chamber of the Berkey with water from your storage tank, allowing it to filter down into the lower chamber for purified drinking water.
4
Distribute Water
Connect the 'Heavy Duty Garden Hose 50 Feet' to the 50 Gallon Horizontal Water Storage Tank, using the 'Brass Ball Valve 1/2 Inch NPT' for control. Ensure the tank is elevated above where you need water to create sufficient pressure for distribution to other uses like washing or non-potable needs.
