A Siamese connection is used for what purpose?

• A. To combine water from multiple outlets or feed multiple lines from one source.
• B. To connect two hydrants directly without a pump.
• C. To regulate pressure in a single line.
• D. To connect a booster hose to a pump.

Answer: (A)

Main concept: a Siamese connection is a fitting that lets you merge water from two separate supply lines into a single, larger feed. In practice, two hoses or hydrant outlets connect to the two inlets, and the combined flow exits through one outlet to feed a large hose or pump discharge. This setup is used when one source alone can’t provide enough water, so you pull water from a second source to boost flow, or you can arrange to split one source into multiple feeds as needed. It’s not about connecting hydrants directly without a pump, nor about regulating pressure on a single line, nor about attaching a booster hose to a pump—the Siamese is specifically about combining or splitting water sources to increase versatility and flow.
