What is the maximum temperature allowed into the drainage system?

The maximum temperature allowed into the drainage system is established to protect the integrity of the plumbing materials and to prevent damage to the system. When hot water enters a drain, it can cause thermal shock, which may lead to cracking or deformation of pipes, fittings, and other components made of materials like PVC, which can soften at elevated temperatures. Furthermore, high temperatures can affect the proper functioning of sewer venting systems and could potentially heat the surrounding environment, causing discomfort or increased risk of accidents.

In accordance with plumbing codes and standards, a maximum temperature of 150 degrees Fahrenheit is generally deemed acceptable to ensure that the drainage system can handle the flow without risk of damage or failure. This regulation is in place to maintain the long-term durability and safety of plumbing systems throughout their lifespan.
