Is it reasonable for the property to charge 3.95 for water?

Reasonable. The water fee charged by the property is reasonable at 3.95, but the property service provider shall not stop power supply, water supply, heat supply and gas supply to urge the payment of the property fee. The parties to water supply and power supply are the owner and the water supply and power supply company, while the parties to the property management contract are the owner and the property management company, which are in different legal relationships.
