Filed as: Plumbing Commission Code Update
South Dakota plumbing contractors and inspectors must now follow the 2024 Uniform Plumbing Code instead of the 2015 version, which updates technical requirements for water supply, drainage, venting, and fixture installation throughout the state. The changes include specific modifications to water heater drip pan requirements, dishwasher discharge piping, backflow prevention, and vent terminal sizing, along with simplified definitions for water conditioning systems. Plumbers and inspectors should obtain the updated 2024 code to understand the new standards, which affect everything from minimum water service sizes to frost protection depths for underground piping.
