We recently moved into our homes and found that our sinks had leakage with an exception of 2. First the plumber tried to blame that the leakage was from us (living in for couple of days). Finally they admitted that the leakage may be the cause of their work. They checked all sinks for leakage and fixed them. When they were done the sinks that had leakage were fixed and the sinks that were okay before, ended up with leakage (from them checking for leakage). Now we have to wait for them again to come back to fix leakage yet again.
