How to install bathroom floor drain

1, according to the diameter of the sewer pipe with floor drain in advance.

Before buying a floor drain, know the diameter of the sewer pipe of the floor drain. Now it is generally 50 PVC pipes, and cast iron pipes are bigger. The diameter of the selected floor drain should match the diameter of PVC pipe. Generally, the reserved drainage hole is relatively large when handing over the house, which needs to be repaired during decoration. The drain should be made according to the size of the floor drain. Don't repair the drain pipe first, then buy the floor drain. Installation of toilet drain pipe >> Selection of bathroom floor drain >>

2, the location of the floor drain installation

When installing the floor drain, try to install it as low as possible. You have to determine the location of the floor drain first, and the floor tiles should be laid until the floor drain has a slope. The floor drain position is best paved with bricks. The floor drain is installed in the middle of a brick, which is diagonal and has the best drainage. If the floor drain is between two bricks, it is installed in this way. Look to the right.

3. Connection between floor drain and sewer:

The sewer interface of a general floor drain can be inserted into the sewer pipe, and the four-proof floor drain can be inserted into the sewer pipe.

Because this floor drain should be equipped with a water seal core, it should not be made too thin. If you add a circle inside, the water seal core must be made thinner, so it is made like this. There is only a small circle stuck on the sewer pipe, which does not affect the installation. If this structure is an ordinary house, there is no problem, because when the floor is waterproof and bricklaying, the floor drain core is aimed at the drain outlet and leveled with cement, which is generally not a problem. But this kind of floor drain is not suitable for frame floor. After installation, it will swing back and forth unsteadily, and there will be gaps. Once the sewer below is blocked, its water will flow into the floor. Fortunately, there are not many such structural layers.

When installing the floor drain, special attention should be paid to the bonding and sealing of the joint between the floor drain and the sewer pipe. The installation should be tight, and it can be sealed with professional glue or glass glue.
