If two 45-degree ell fittings are spaced how many feet apart, a cleanout is not required?

In plumbing systems, the placement of cleanouts is essential for maintaining the ability to access and clear blockages. According to plumbing codes, when two 45-degree elbow fittings are used to change the direction of drainage, their spacing plays a crucial role in determining if a cleanout is necessary.

When two 45-degree fittings are used in succession, they create a change in direction that is considered less severe than using a single 90-degree fitting. The code typically allows for a certain distance between these fittings where a cleanout is not required. In this case, 3 feet is the specified distance that must be maintained between the two fittings to forgo the need for a cleanout. This distance is advantageous as it allows for adequate access in most situations without the need for additional cleanout fittings.

The number of feet mentioned takes into account factors such as ease of access, potential buildup of waste, and overall efficiency of the drainage system. While other options present larger distances, they do not adhere to the code’s requirement for spacing between fittings that eliminates the need for additional cleanout access. Hence, a distance of 3 feet is optimal and aligns with plumbing standards.
