Modern-day water and drainage systems would be unimaginable without tee fittings – and that’s not an exaggeration. Their design and build make them incredibly versatile, capable of accommodating a broad array of applications in various settings.

As if versatility isn’t enough, PVC saddle tees are beyond easy to install and come at an affordable price, which is exactly why they became the go-to choice for the majority of contractors across the US.

In our previous article, we introduced different types of tee fittings, focusing on two specialized variations: saddle tees and Inserta Tees. Now, it’s time to see what their purpose is and how they are utilized in different settings.

What is the purpose of a tee in PVC pipe?

The primary purpose of PVC tee fittings is to create safe, water-tight, and air-testable branching connections in water, drainage, and occasionally, gas and air plumbing systems. The most common uses include:

• Splitting fluid, gas, or air flow into two separate (branching) pipelines;
• Combining fluid, gas, or air flow into a single pipeline;
• Redirecting fluid, gas, or air flow at a 90-degree (lateral) angle.

These functions are highly generalized and apply to the majority of tee connectors. So, let’s dive deeper and explore the purpose and application of our star fitting types.

What are inserta tees used for?

Inserta Tee® fittings are primarily used to create a watertight, air-testable lateral branch from the main pipeline. Thanks to their simple yet ingenious design, the installation process of Inserta Tees is among the most streamlined in the industry.

The fitting is compatible with different pipe sizes and materials, doesn’t require any specialized tools to install, and involves only minimal alterations to existing pipes. That’s exactly why it is a preferred choice in many applications, the most notable being:

• Sewer & stormwater systems: Allows for easy lateral connection formation without extensive pipe modifications;
• Underground drainage systems: Creating secure connections that can withstand harsh environmental conditions;
• Retrofitting: Allows the upgrade of existing systems without having to cut or remove entire sections of existing pipes;
• Municipal & commercial systems: Preferred choice for its affordability, ease of installation, and long-term durability even with heavy use.

What are saddle tees used for?

The main purpose of saddle tees is to create a branch connection on an existing pipe, splitting or combining fluid, gas, or air flow. Similarly to Inserta Tees, saddle connectors do not involve cutting or removing sections of the pipe, which is why they are the preferred choice for hot tapping into existing systems. Saddle tees are most commonly used in:

• Irrigation systems: Quick and easy way to add a branching water supply line for different purposes, such as to create a mounting point for sprinklers;
• Sewer systems: Used instead of Inserta Tees for adding a lateral connection to the existing sewer line;
• Venting systems: Connecting new lines to existing vent stacks for the purpose of improving airflow and preventing drainage issues;
• Compressed air systems: Provides an additional outlet without the need to replace piping or retrofit the entire system, at the same time preventing pressure buildup.
