What is a potential consequence of failing to ventilate long interior drainage piping?

Failing to ventilate long interior drainage piping can lead to rapid fouling of the pipe. Proper ventilation is essential in drainage systems as it allows air to enter the piping network, which helps maintain a balance between pressure in the system and prevents the creation of vacuum conditions. Without adequate ventilation, the flow of wastewater can slow down, leading to sediment and organic matter accumulating inside the pipe, which contributes to fouling. This fouling can result in blockages, reduced flow rates, and increased maintenance needs. Therefore, ensuring proper ventilation is crucial for the efficient operation and longevity of drainage piping systems.
