Whether the drain pipe of the toilet bowl needs a trap

The toilet itself has its own anti-trap, so there is no need to install a trap underneath.

The flush toilet itself has a trap for deodorization. Therefore, when installing a flush toilet, there is no need to retain a water bend in the sewer pipe, otherwise it will affect the sewage effect.

It is necessary to install a trap, which is an accessory that sets a certain height of water column on the drain pipe of sanitary appliances or inside the sanitary appliances to prevent gases in the drainage pipe system from escaping into the room.

The trap is one of the main accessories of the drainage pipe in the building, and some sanitary appliances have a trap (such as a sitting toilet) in the structure, and the structure is not connected with the industrial wastewater receiver and the domestic sewage pipe or other drainage pipes that may produce harmful gases, a trap must be set up below the drainage outlet.

A certain height of water column (generally 50 100 mm) is formed in it, and the water storage height of this part is called the water seal height, which can prevent all kinds of polluting gases and small insects in the drainage pipe from entering the room. In order to ensure the normal function of the water seal, the design of the drainage pipe must be considered to be equipped with appropriate ventilation pipes.

1. Before choosing a toilet on the market, first determine the size of the water in the seat (i.e., the distance from wall to wall). Before installation, please make sure that the product accessories you choose, completed, please carefully review this manual and learn about some products.

2. Determine the height of the drain according to the condition of the toilet and cut off the rest of the part. The goal is to make the plumbing and toilet bottom more consistent. Start by using a hacksaw or cornea for the sewer according to the horizontal height of the centimeter, because the flange of the toilet bowl is soft.

If it is not centimeters high, there may be water seepage problems, and centimeters are more tightly fitted.

3. Measure the pit distance. Before choosing a toilet, first determine the size of the water inside the house, that is, the distance from the wall to the water. When using a toilet, if you want to decorate the tiles, you must measure the pit distance after applying the tiles. Otherwise, the toilet will be bought back and cannot be installed.

4. Install the flange ring provided with the toilet at the drain. Remember to press hard to ensure the compaction of the flange ring and toilet drain. Place the flange on the toilet drain.

Then carefully align the lower hose and lower it smoothly. At this point, the wall of the sewer pipe is inserted into the viscous clay of the flange for sealing.

5. After the water test is completed, start to install the cover.

6. Glue around the toilet, this step is also very important, not only to stabilize the toilet, but also to prevent the smell of the net from being released from the toilet. Therefore, we will not only fight, but also four whole weeks. At the intersection of the toilet bowl and the outer surface of the floor, since the toilet bowl and the floor are not one, a joint seal transparent sealant can be used for agitation, and the outer opening of the toilet bowl is sealed to maintain the integrity of the floor.

Some bathroom water can clog around the toilet bowl. NOTE: IF YOU NEED TO INSTALL THE SET SCREWS, FIRST APPLY A SPECIAL SEALANT INSTALLED IN THE TOILET BOWL EVENLY ON THE OUTSIDE 2CM OF THE TOILET BASE.

The drain of the toilet bowl should be pulled towards the center of the drain. Expansion bolts are located on the left and right sides of the toilet, remove the toilet, punch holes and raised bolts.

7. Install or debug the water tank accessories.

8. After installing the toilet, wait until the glass glue (putty) or cement mortar has solidified before releasing water. The curing time is usually 24 hours.

It is problematic to install toilets in places where there are water storage curves, and it may turn two turns when discharging sewage due to the common curve of the toilet and the sewer curve, resulting in poor sewage discharge.

However, in decoration practice, it is best to change the original water trap and then install a toilet, but the change is very troublesome. Toilets are usually installed according to the owner's requirements without changing the original curve.

Therefore, if it is too troublesome, you can also install the toilet directly.

Generally, the toilet has its own water seal (water trap), and there is no need to install a water trap, if it is a squatting pit and does not have its own water seal, you need to install a water trap.

The toilet itself comes with a U-shaped bend. No additional configuration is required.

Of course, you need a trap, only then will it not smell, so that the water can flow down faster.

Yes, so the toilet drain pipe must have a trap to use normally.
