This is a residential central system installed in an apartment complex completed in 1982.
We replaced the water heating system installed in the pipe shafts of the aging private units.
The operation of the hot water system was checked, faulty equipment was replaced, and aging branch pipes were replaced.
In the case of aging systems, there are many malfunctions that prevent the water shutoff valve from shutting off the water, but we conducted a thorough preliminary investigation and completed the work in the minimum amount of time required to shut off the water.
The construction period was approximately 3 months for 4 buildings with approximately 500 units.
