Is the domestic flue installed above or below the ceiling?

Generally speaking, the family flue is installed above the ceiling and below it. Each has its own advantages. Let me tell you something about it.

A flue above the ceiling

For the flue installed on the ceiling, it is necessary to reserve flue pipes, otherwise the flue cannot be installed after the ceiling is installed. But if the flue stays in the ceiling, it will be more troublesome for future maintenance. If it is broken, several ceilings will be removed before maintenance.

A flue under the ceiling

The flue installed under the ceiling does not need to be reserved, and it can be installed and disassembled by itself. The range hood is installed behind cabinets, kitchen countertops and ceilings. The advantage is that when installing cabinet countertops, sometimes it is necessary to polish the countertops, which is too violent. Some workers are irresponsible. After your range hood is installed first, it may not be covered with plastic sheets or something, and there will be dust.

Do you need a pipe check valve?

Generally, the master who installs the range hood will ask if you need the check valve of the pipeline after you go, which is used to prevent odor. The prices of check valves are basically above 100. You can use it.
