Which type of fittings are used to ensure proper drainage of water?

The use of eccentric fittings is crucial in ensuring proper drainage of water in a piping system. Eccentric fittings maintain a consistent alignment throughout the piping system, which is essential for allowing gravity to facilitate fluid flow without creating air pockets. This design helps to avoid situations where the water may stagnate or cause blockages, ensuring that drainage occurs effectively.

By being designed to maintain an even flow path, eccentric fittings prevent turbulence and allow for a smooth transition of water. This is particularly important in gravity-fed systems where the water must flow downhill without obstruction. Utilizing these fittings leads to better efficiency in drainage systems and reduces the risk of backup caused by uneven water flow or trapped air bubbles.

In contrast, removable fittings, orifice fittings, and tapered fittings do not provide the same level of effectiveness in promoting smooth drainage. While they have their specific applications, they lack the optimal design necessary for maintaining an uninterrupted flow, which is why eccentric fittings are favored in situations requiring efficient water drainage.
