Good night televised dogs as water was up to the top. Water is clean and comes back as soon as it is pumped out. Suspect that there could be a leak on the freshwater line. Listened to supply line in her unit, but did not hear or detect any leak on her waterline, and the meter does not move when no water is in use. suspect that there could be an issue with a waterline in one of the neighbors units. Bugs or flies could be because the floor drain was very low. Suggested to homeowner that she should pour water down the floor. Drain to keep the level.
