A Guide to Mechanical Tees for Fire Sprinkler Systems
Tees are pipe fittings with three outlets—two in a line and a third 90 degrees between them. In fire sprinkler systems, a heavy main water line carries water through the building, and lighter branch lines distribute it to the sprinkler heads. Tees connect branch lines to the main lines and account for various changes in elevation and the direction of pipe and water.

What is a check valve used for?
A check valve is typically installed in a pipeline to prevent backflow. A check valve is basically a one-way valve in which fluid can flow freely in one direction, but if the flow is diverted the valve will close to protect the pipeline, other valves, pumps etc. Water hammer can occur if the flow is diverted and no check valve is fitted. Water hammer often occurs with great force and can easily damage pipework or components.
