Is it the responsibility of the property to repair the leaking water pipes in the old community?

Dear you, water pipe leakage is mostly a problem of installation or product quality. This piece does not belong to the scope of property maintenance. Unless you have an agreement with the property, the property is responsible for leaking pipes.

I don't know what brand of pipe you have here. In the industry, like Wei Xing pipe, there is now a star butler service. If it leaks, the manufacturer will repair it. If the purchase time is not very long, you can consult the pipe manufacturer.
