What size hose is used to take suction on a P-100?

The P-100 is a lightweight, portable pump used primarily for firefighting and water supply operations. It is notably designed to handle significant volumes of water efficiently. The correct suction hose size for the P-100 is indeed 3 inches. This size strikes a balance between allowing adequate water flow while remaining manageable for operators during setup and movement.

Using a 3-inch hose ensures that the pump can maintain a proper vacuum pressure necessary for effective suction, enabling it to draw water from sources such as ponds or reservoirs. The 3-inch diameter also allows for better mobility and handling compared to larger hose sizes, which can be cumbersome in many field conditions.

In contrast, smaller hose sizes like 2 inch would restrict water flow too much, potentially affecting the pump's performance. Larger sizes, such as 4 or 5 inch, are typically unnecessary for the P-100’s design and could present challenges in handling and setup, as well as requiring more powerful attachments or fittings.
