What type of fittings are designed to ensure proper drainage of water?

Eccentric fittings are specifically designed to facilitate the proper drainage of water by allowing for the effective flow of fluids with minimal likelihood of trapping air or debris. Their unique shape enables the alignment of different pipe sizes and helps maintain a steady flow path, reducing the risk of blockages that could cause water to stagnate.

To elaborate, the eccentric design features a flat side that helps to control the flow while facilitating drainage. This design is particularly useful in applications where proper drainage is critical, such as in plumbing systems and HVAC installations.

Tapered fittings, while useful for connecting pipes of differing diameters, do not inherently possess the features that promote effective drainage. Orifice fittings serve a different purpose, mainly for controlling flow rates rather than concentration on drainage. Removable fittings provide flexibility in accessing pipe systems but do not specifically focus on drainage capabilities.

In summary, eccentric fittings are optimal for ensuring efficient drainage due to their design that prevents air pockets and supports a consistent flow of water.
