Maximizing Fire Hydrant Flow with a Triple Tap Configuration
“We printed out the guide and gave it to our probies – thanks guys.”
Unlocking the Full Potential of Your Hydrant
When it comes to heavy hydrant operations, maximizing available water flow is crucial. Standard single connections often limit a hydrant’s capacity, but with the triple tap hydrant configuration, you can extract the most volume possible from a hydrant’s three outlets.
Some fire departments face challenges with limited gate valves, preventing them from taking full advantage of a hydrant’s output. However, by integrating a four-way hydrant valve, you can optimize hydrant performance—even with minimal equipment.
This article will guide you through the steps to execute a triple tap hydrant configuration, ensuring you get the highest flow possible for large fire incidents.
What is a Triple Tap Hydrant Configuration?
A triple tap hydrant configuration involves connecting three supply lines to a single hydrant to maximize its water output. This setup provides superior fire flows and ensures the pumper receives maximum available volume.
Why It Matters
Key Steps to Perform a Triple Tap Hydrant Configuration
1. Position the Four-Way Hydrant Valve
Attach the four-way valve to the hydrant’s steamer port as you normally would.
Cap off one of the two fire ports if only two immediate connections are needed.
2. Establish the Primary Water Supply
The first large-diameter hose (LDH) is connected to the two-fire port and routed to a large intake on the supply pumper.
Water begins flowing into the pumper to establish the initial supply.
3. Implement the Second Hydrant Connection
Utilize the relay pumper inlet on the four-way valve to establish a second supply line.
The second line connects to another large intake on the supply pumper, effectively doubling water intake.
4. Utilize a Gate Valve for the Third Tap
A hydrant gate valve is attached to one of the side 2.5-inch ports.
A third supply line is routed from this valve to a separate intake on the supply pumper.
5. Adjust for Maximum Flow Efficiency
Ensure all hose layouts minimize kinks and unnecessary bends.
Monitor intake pressures to ensure even distribution of water flow.
If additional intakes are available, consider a quadruple tap hydrant setup.
Don’t rush the setup—build your system one connection at a time. Establish each water source before moving to the next to prevent pressure drops.

Common Mistakes to Avoid
Mistake 1: Trying to Connect All Lines at Once
Build the system step by step to maintain steady pressure.
Mistake 2: Ignoring Friction Loss
Ensure hose lengths and layouts minimize unnecessary bends and kinks.
Mistake 3: Forgetting Hydrant Gate Valves
If available, always use them to expand water intake capabilities.
