(1) Septic Cleaning: To undertake hotels, guesthouses, restaurants, kitchen sewage treatment plant, strong suction sanitation truck pumping manure, septic tank cleaning, septic tank design customized to detect, and with a suction truck, sewage suction trucks, high pressure pipe cleaning vehicles, high pressure cleaning vehicles to clear the type of municipal drains, pipe cleaning altitude, (2) pipe cleaning: pipeline construction, pipeline dredge, pipeline inspection, leak detection, water plugging, pipeline pressure cleaning, high pressure grouting, wall surface water, toilet water, decorating pipe cleaning: Clean water pipes, water pipes, industrial sewage pipe network, smoke pipe cleaning and other specialized cleaning center. Pressure pulse technology is the use of high-speed jet, physical controllable pulse wave formed to carry out rust tube shocks and shock layer by layer peeling rust and the deposits and rapid discharge tube, can significantly efficient solution because the old pipe network rust, the deposits excessive blockage caused by poor, inadequate water supply, poor sewage problems. Second, dredge (1) clear the various municipal pipelines, blocking the main channel and other large underground pipe. High pressure cleaning vehicles of various pipelines. Difficult sewers, municipal pipelines, all the residents in charge of building the riser, head of the pipeline. (2) toilet: dredge for rags, towels, plastic, cleaning balls and other soft and hard materials caused by the blockage broke into the toilet.

(5) bath vanities: clear all types of bathtubs, vanities, vegetables pool, including the V-bends and S-bend and other channels. (6) various other difficult blocked. Dredging, maintenance, installation department dredge drilling engineering professionals: a toilet, pit, toilet, toilet, floor drain, vegetables pool, bathtub, municipal pipelines, sewer.
