When setting up irrigation, farmers often ask:
“Should I use a reducing tee or a saddle to connect my submain line to the main pipe?”
Both fittings have their uses, but choosing the right one can save you water, energy and future repair costs.
1. What is a Reducing Tee?
A reducing tee is a T-shaped fitting that smoothly diverts water from the main pipe into a smaller submain line.
– Advantage: Water flows more freely with less resistance.
– Best for: Larger blocks carrying significant flow (sprinklers, rainguns, submain lines).
2. What is a Saddle?
A saddle is a clamp fitting placed around the main pipe. A hole is drilled in the main, and the saddle directs water into a small submain line.
– Advantage: Quick and affordable to install.
– Best for: Small blocks like drip irrigation, where each submain carries a small amount of water. It can also be used to adapt air release system: Read more https://goldenstarfarming.co.ke/the-role-of-air-release-valves-in-irrigation-and-water-systems-in-kenya-enhancing-efficiency-for-farmers-and-households/
3. Considering Flow Rate
Flow rate is the key factor in deciding which fitting to use:
– High Flow (Sprinklers, Rainguns, or Large Blocks):
Use a reducing tee. It gives smooth water flow, reduces pressure loss, and avoids turbulence inside the main pipe.
– Low Flow (Drip Irrigation in Small Blocks):
A saddle works fine if each outlet takes only a little water (less than 10–15% of the main flow).
4. Simple Rule of Thumb
– If your submain line is 1/3 or more of the main pipe size → use a reducing tee.
– If your submain is very small compared to the main pipe → a saddle is acceptable.
5. Why It Matters for Farmers
– Choosing the right fitting reduces pressure loss and ensures all blocks get water evenly.
– Prevents frequent leaks and repairs.
– Saves money on pumping costs by improving efficiency.
