Chongshang Road Underground Garage Drain Jetting Service Report
This service was provided by Yongzheng Engineering at the Chongshang Road community’s underground garage. Over the years, grease, dirt, and scale accumulated in the underground drainage system. Using a high-pressure water jet, we performed deep cleaning and pipe unclogging to restore smooth flow, effectively reducing the risk of flooding and blockages. The entire operation was quick, eco-friendly, and did not require surface removal, significantly improving drainage efficiency and resident safety.
