Heating-pipe/valve leak repair in Hongda’s own service introduction.
The company advertises repair of leaking heating pipes and valves in its own service list. Explain the observed leak and identify the affected heating circuit before requesting an assessment. Confirm the repair boundary, any required isolation and replacement components with Hongda rather than assume every fault can be resolved without component replacement.
