The kitchens of high-rise buildings usually use public flue, which is prone to the problem of flue odor. Installing a check valve can effectively prevent the smell of oil smoke from entering the home and protect your cooking experience.

Pay attention to the direction when opening the check valve

When opening the check valve, pay attention to its direction and ensure that it is opposite to the direction of the hood pipe to ensure the normal use of the check valve.

Ensure tight combination and plug the gap.

After the check valve is installed with the public flue or household flue, ensure the close combination. If possible, it can be blocked with sticky putty to prevent the smell of lampblack from entering the home.

Make sure there are no gaps to avoid air leakage.

After installing the fixed check valve, make sure there is no gap between the smoke exhaust pipe and the check valve to avoid air leakage.

Choose a brand with good closing effect.

When purchasing check valves, it is recommended to choose brands with good sealing effect, such as submarines, to ensure the normal use of check valves.
