Off Grid Gravity Fed Water System Components

This bundle outlines the core components for an effective off-grid gravity-fed water system. It provides solutions for water collection, storage, filtration, and distribution. Ideal for homesteaders, cabin owners, or anyone establishing an independent water supply, these products collectively ensure a reliable and sustainable water source.

Curated by The Shelf Curator · Updated June 2026

Built for off-grid property owners who require high-pressure, potable water delivery without a municipal connection. Not for urban households or temporary camping setups—this shop focuses on permanent, high-flow residential infrastructure for homesteads.

Curator's pick: Waterdrop G3P800 Reverse Osmosis System

This unit earns its place due to the 800 GPD flow rate and tankless design, which eliminates the storage footprint and stagnation risks common in low-pressure off-grid systems. The smart monitoring circuitry provides precise TDS tracking, essential when drawing from varied raw water sources like rainwater or wells.

⚠ Worth knowing: The Rheem 11kW tankless heater requires a high-amperage dedicated circuit that can overwhelm small solar battery banks during peak draw. A system with less than 20kWh of storage or a low-wattage inverter will likely see significant voltage drops when the heating elements engage.

How to use this together

  1. 1

    Install Water Collection & Storage

    Begin by installing the RainFlo Rainwater Collection Tank in a strategic location to maximize rainwater harvesting. Ensure proper guttering and downspouts are directed into the tank. This is your primary water source and must be positioned appropriately for collection.

  2. 2

    Set Up Pumping System

    Next, integrate your Vevor Solar Powered Submersible Well Pump to draw water if using a well, or connect the Shurflo Fresh Water Pump to distribute water from your RainFlo tank. Follow up by installing the Amtrol WELL-X-TROL Pressure Tank to ensure consistent water pressure and extend your pump's lifespan. The pressure tank should be placed after the pump.

  3. 3

    Integrate Water Heating & Filtration

    Finally, plumb in the Rheem Performance 11kW Tankless Electric Water Heater for on-demand hot water, followed by the Waterdrop G3P800 Reverse Osmosis System to purify water for drinking and cooking. Place the filter last in line for the highest water quality.
