Is the property closed?

There is a main water valve in your house. At the front end of your cold water meter, you can ask the plumber of the property to turn off the water valve for you. Just open the hot water pipe after it is repaired, without closing the main valve in the building.

Generally speaking, the property will take care of this matter, but repairing hot water pipes may charge you a certain maintenance fee. After all, the maintenance of indoor self-use equipment and facilities is not within the property maintenance work.
