Rain and ground water go to a sump pump, your floor drain should go to your sanitary sewer by either gravity or by a pump. the water holding in the floor drain is normal , a floor drain is trapped under the floor and hold s water so you don't get sewer gas in the house. The elvation of water in the trap doesn't have to be the same as your neighbor,
it all depends on the depth of the sewer under your floor,
