Two-way cleanouts are not required on building storm drains if the storm drain drains to daylight how far from the building?

The requirement regarding two-way cleanouts for building storm drains is based on the distance from the building to the daylight outlet. If a storm drain discharges to daylight within a specified distance, it alleviates the need for two-way cleanouts because the drainage system is accessible for maintenance and can adequately be cleaned from one end.

In this case, the correct distance specified in the plumbing code is 50 feet. When the outlet is within this distance, it allows for effective drainage without creating potential blockages that would necessitate the installation of cleanouts to facilitate ease of access for future maintenance. This adherence to code helps ensure efficient operation of the drainage system while minimizing unnecessary installations that could increase costs and complexity without added benefit.

Further distances listed in the other options suggest a misunderstanding of the code requirements, as the plumbing code specifically sets the threshold for cleanout necessity at 50 feet. Thus, in the context of Omaha Plumbing Code, any storm drain that drains to daylight beyond this distance would typically require additional considerations for cleanouts, but within 50 feet, it is deemed sufficient.
