Each unit has a different level of power. Some dealers can determine the size through a few fundamental questions, without even stepping foot on the property. You and the homeowner must determine where valves will provide optimal use. Consider possible obstacles, such as the placement of furniture, as well as future decorating changes, cabinets, and doors. All of these things can impede hose movement.
Most installations typically have two inlets per floor, in either the floors or walls.
Oliver says that more inlets doesn t necessarily mean more convenience. Remember, a standard C-Vac hose is about 30 feet long. Your client may not want 30-foot hoses hanging in every room. But more inlets do equal more expense for the client. The inlets should be located so that they have a good reach to all areas, such as corners and under beds.
