Is the kitchen chimney and toilet exhaust pipe good for a 4 storey building? There is an exit on the

The exhaust flue is vertically channeled with a concrete pipe (or bucket skin brick 35X35cm), and a rain and snow cover should be made after the roof from the 2nd floor to the top floor. A single 11oprc pipe can be used for drainage, and the roof is 2m high for deodorization.

Old houses generally lead directly to the outside through the wall, which is a relatively simple but not very aesthetically pleasing method. If you want to connect the smoke exhaust and ventilation equipment in your kitchen and bathroom to the roof of the building, you can also do it.

The recommended construction methods are as follows:

1: First calculate the direction of the smoke exhaust ventilation pipe (according to the drawings you gave, it is recommended to see if the roof exit is reserved on each floor, if there is, arrange workers to do the corresponding docking inside each floor, if not, just like the air conditioning hole, after the hole is drilled along the exterior wall and the roof exit can be docked. ）

2: Calculate the length of the pipe and the amount of auxiliary materials (toilet ventilation generally uses PVC pipes, 4-storey buildings do not need to be considered particularly large, the diameter can be 45-75, kitchen smoke exhaust considering that the smoke is temperature, so it is recommended to use stainless steel iron wrapped smoke pipe is the best, just like many restaurants do kitchen smoke exhaust. ）

3: Find relevant workers to open holes and lay pipes, and conduct sealing and smoke exhaust experiments. (The general home improvement hydropower workers can do laying, the price of plumbers is 220-300 yuan a day, the specific price fluctuates according to different regions, and after the construction is completed, we must pay attention to the waterproof treatment, and do not solve the smoke exhaust but leave the hidden danger of water leakage).

Yes, the exhaust pipe of the bathroom is set in a corner of the bathroom, and the kitchen is also set in the corner, which must be set separately and cannot use a pipe.
