Drain-pipeline installation/modification in Hongda’s own service introduction.
The company’s introduction names installation of PVC, cast-iron and cement drain pipelines together with drain modification work. Provide the existing layout and requested change before seeking a proposal. Confirm pipe material, junction details and the agreed installation boundary with Hongda for the actual project instead of treating the broad service list as a completed design.
