One of the most practical and popular uses for IBC totes is gravity-fed dispensing. Elevate a tote on a stand, open the valve, and you have a simple, reliable, pump-free liquid distribution system. No electricity, no moving parts, no maintenance beyond occasional valve replacement.
At IBC Kentucky, we help customers set up gravity-feed systems for applications ranging from workshop handwash stations to farm irrigation headers. Here's how to do it right.
The Physics: How High Is High Enough?
Gravity-fed water pressure depends entirely on the height of the water surface above the discharge point. The formula is simple:
Pressure (PSI) = Height (feet) × 0.433
So:
For comparison, a standard garden hose operates at 40-60 PSI. So gravity-fed pressure is much lower — but it's often enough for many applications.
What can you do with gravity pressure?
Designing Your Stand
The stand needs to support a full IBC tote — approximately 2,500 lbs for a 275-gallon tote filled with water. This is not a weekend project with scrap lumber.
Steel frame (recommended):
Engineered wood (alternative):
The stand height depends on your required pressure. For most applications, 4-6 feet of elevation (measured from ground to the bottom of the tote) provides adequate flow.
Plumbing the System
Basic setup: 1. The IBC tote sits on the elevated platform 2. A ball valve (recommended over butterfly for zero-drip shutoff) controls the main discharge 3. A reducer adapts from the 2" tote outlet to your distribution piping (typically 3/4" or 1") 4. Distribution piping runs to your dispensing points
Piping recommendations:
Important: Install a shutoff valve directly at the tote, then any additional valving downstream. This allows you to isolate the tote for maintenance without draining the entire system.
Flow Rate Calculation
Flow rate through a gravity system depends on:
As a rough guide for a 275-gallon tote elevated 4 feet:
These are approximate — actual flow depends on many variables. For critical applications, test your specific setup.
Practical Tips
Install a sight gauge. Knowing how much liquid remains without climbing up to check saves time. A simple clear tube running vertically alongside the tote (connected at the bottom) shows the water level at a glance.
Add a screen filter. Even clean water can carry sediment. A simple inline screen filter between the tote and your distribution piping prevents clogged drippers and nozzles.
Plan for refilling. How will you refill the tote when it's elevated? Options include a pump-fed supply line, a garden hose from a pressurized source, or a second tote at ground level with a transfer pump. Plan this before you build — it's frustrating to discover you can't easily refill an elevated tote.
Consider a manifold. If you need multiple dispensing points, install a manifold (a pipe with multiple tapped outlets) at a convenient height. Each outlet gets its own valve for independent control.
Winterization. If your system is outdoors in Kentucky, drain it before the first freeze. A frozen elevated tote is a cracked elevated tote. See our winterization guide for details.
Common Applications
The beauty of gravity-fed systems is their simplicity and reliability. No pumps to fail, no electricity to pay for, no moving parts to maintain. Just gravity, doing its thing.
