When installing the floor drain, the floor drain is inserted into the sewer pipe and the faults left by the floor drain and the sewer pipe. The specific analysis is as follows:
1. Inserting the floor drain into the sewer pipe
– Advantages: It can prevent bath water from penetrating into the mortar layer through the fault, reducing the probability of problems such as alkali return, mold, and water soaking on the floor. It can maintain the integrity and sealing of the ground drainage system, effectively preventing odor from spreading from the sewer pipe through the fault into the room. The installation is relatively simple and does not require additional consideration of complex issues such as fault treatment and sealing.
– Disadvantages: There is a problem with the beautiful joints of local bricks. When a small amount of water seeps into the mortar layer, there is no secondary drainage channel provided by the fault, and it is difficult to discharge the accumulated water in the mortar layer.
2. Faults left between floor drain and sewer
– Advantages: It can be used as a secondary drainage channel. After the water on the surface of the local tiles penetrates into the mortar layer through the beautiful joints or tiny gaps in the ceramic tiles, it can flow into the drain pipe through the fault to alleviate the water accumulation problem of the mortar layer. The fault design can effectively increase the drainage speed, and the accumulated water can be drained quickly, reducing the risk of slipping and falling. After normal drainage, the water remaining in the fault can effectively prevent the odor in the sewer from surging.
– Disadvantages: The construction requirements are high. If the faults are not handled well during installation, such as the connection between the floor drain and the sewer pipe is not tight, or the fault surface is not waterproof and sloped, it is easy to cause water leakage, causing water seepage downstairs and neighborhood disputes. Cleaning is difficult, and dust, hair and other debris can easily accumulate in faults and are not easy to clean thoroughly. If the floor drain core is too short or is selected improperly, the water may continuously wash away the fault during the water use, resulting in excessive water immersion into the sand ash layer.
To sum up, when installing the bathroom floor drain, you must slop the floor drain around it, and prepare a waterproof protective layer. The drain drain outlet faces the sewer pipe, so that the water accumulation on the base layer can be removed.
