Reserve the size of the toilet drain and the size of the toilet drain

Generally speaking, the length of the toilet bowl is 30 cm or 40 cm. If the bathroom has not been paved with wall tiles at the time of measurement, the thickness of the tiles should be reduced by the results of the measurement team, and the reserved thickness of the wall tiles is about 2 cm.

Use a measuring tape to measure the distance from the wall to the sewage outlet, after measuring the pit distance of the toilet is just right, then you can save a lot of effort, if the pit distance is not suitable, you should also consider using a disposer to do a good job of displacing the toilet.

Toilet reserved space precautions.

Before installing the toilet, remember to check the sewage pipeline, check whether there is silt or waste paper and other debris in the pipe, and check whether the ground at the toilet installation location is level, and the uneven ground should be leveled. Cut the drain short, and if possible, try to raise the drain about 2 5 mm above the ground.

It is best to understand the size of other toilets at the same time, such as 70cm*40cm is the specific size of a toilet, and it is also necessary to consider that the installation of the toilet bowl should leave at least 80cm*120cm space, which is the space where the legs can be expanded when people are squatting, and 120cm is the space required for squatting and leaning forward. Take the size of a toilet as an example, 80cm*120cm refers to the size of the toilet itself, in addition, we also have to reserve more space for use.

Also, about toilet tank accessories. Drain the water for 3 to 5 minutes before use to flush the pipe, install the angle valve and connecting hose, and then connect the installed hose with the water inlet valve and connect the water source. After the above work is completed, start the debugging of the toilet bowl and check whether the installed toilet has any leaks or other abnormal conditions.

Extended Materials. Toilet is a sanitary appliance in the field of building water supply and drainage materials. The main technical characteristics of this utility model toilet are that:

In the upper part opening of the existing toilet S-type water trap, install a cleaning bolt, similar to the installation of inspection port or cleaning mouth on the drainage pipe to clean up the blockage, after the toilet is blocked, the user himself can use this cleaning bolt to remove the blockage conveniently, quickly and hygienically, and is economical and practical.

The toilet is technically characterized in that a toilet toilet bowl is installed at the upper part opening of the existing toilet S-type water trap bend, and its cleaning bolt is mainly made up of an inspection mouth and a cleaning bolt gun, and the inspection port is embedded on the reserved mouth of the upper part of the S-type trap trap, and the cleaning bolt gun is a tool used for removing the blockage.

According to the flushing method, it is divided into direct flush type and siphon type (siphon type is divided into jet siphon type and vortex siphon type).

The diameter of the toilet should be 110mm PVC drainage pipe, and according to the different position of the toilet drain, the distance between the toilet wall and the pipe can be between 30 cm, 25 cm, and 18 cm. However, most of the sewers are located at 25 cm. I hope you find my explanation helpful.

The toilet drain is reserved between 75 and 90 dm, 30 to 40 cm from the wall. The diameter of the toilet sewer pipe is usually 110mm. At present, the toilet sewer pipe in the bathroom is generally a U-PVC pipe with a diameter of DE110, which is large in size, smooth in inner wall, and not easy to block.

Before the toilet is installed, the first thing is to understand the size of the toilet sewer pipe, the size of the sewer pipe of the pipe is usually 75dn and 90dn, mainly referring to the size of its outer diameter. If the outer diameter is 90mm, the PVC-U pipe means that it is a 90 PVC pipe. If your bathroom PVC-U pipe is connected to a cast iron drain pipe, then the drain pipe specification selected for the lock should be DN75.

The width of the toilet is generally 30-50 cm, which is slightly different according to the shape of different styles. Under normal circumstances, the width of 50 cm can be reserved for installation. The height of the toilet is generally about 70, and the smallest is 62 cm.

In fact, the height of the toilet does not affect the installation effect, and there is no need to consider it in advance when installing.

Precautions for toilet installation

1. Check whether there is glaze in the backwater bend.

The glaze of the toilet bowl should be very smooth, smooth and free of any defects; There can be no needle eye and lack of glaze. Many toilets on the market use low-density, rough toilets. Touch if necessary to see if it is smooth.

2. The pit distance is accurate and easy to install.

The pit distance refers to the distance from the core of the drain to the wall behind the tank, and the error cannot exceed 1 cm. Otherwise, the toilet cannot be installed; The pit spacing of the drainage method is the distance from the core point of the ground sewer hole to the undecorated wall.

The toilet drain is reserved for 40 cm from the wall.

Toilet is a sanitary appliance in the field of building water supply and drainage materials. The main technical characteristics of this utility model toilet are that: in the upper part opening of the existing toilet S-type water trap, install a cleaning bolt, similar to the drainage pipeline to install the inspection port or the cleaning mouth to clean up the silt, after the toilet is blocked, the user can use this cleaning bolt to remove the blockage conveniently, quickly, hygienically, economical and practical.

This also depends on the specific model of the toilet you buy. Usually the pit distance of the toilet is 300mm or 400mm, and when installing the toilet, a distance of 20mm between the wall tiles should be reserved, so in actual operation, the actual distance from the center line of the toilet drain to the wall is 320mm or 420mm. The actual error is within 10mm, which is normal.

Pit distance refers to the distance between the center of the toilet sewer pipe and the wall, generally 300mm, 350mm, 400mm, 450mm, etc. Choosing the right toilet starts with choosing the right pit spacing.

When choosing a toilet, if you are going to decorate and paste tiles, you must measure the pit distance after pasting tiles, otherwise there will be a problem that the toilet will be bought back and cannot be installed!

The building code requires that the distance between the center of the toilet mouth and the living wall is between 300-400, and the general civil engineering should be reserved between 350-370 before decoration, and the reserved size is for tiling and leveling, and the toilet hole on the market is mostly 300.

The toilet toilet drain is reserved, and the size of the wall is 300mm or 400mm. At the same time, in actual operation, a distance of 20mm wall tiles should be reserved. Therefore, the actual distance from the center line of the toilet drain to the wall is 320mm or 400mm.

The toilet drain is reserved between 75 and 90 cm and 30 to 40 cm from the wall. The distance between the toilet and the wall is generally 30 to 40 cm. The wall spacing standard of the lower drain toilet drain should be equal to or slightly less than the wall distance of the toilet drain, and the distance between the rear drain toilet drain and the ground should be equal to or slightly higher than the height of the toilet drain.

When installing the toilet, it is necessary to measure the pit distance of the toilet, which refers to the distance from the core of the drain to the wall behind the water tank, and the error cannot exceed 1 cm, otherwise the toilet can not be installed. The pit spacing of the drainage mode is the distance between the core point of the ground sewer hole and the undecorated wall.

The center of the nozzle is 40 cm from the wall. I hope my answer can help you.

According to the national standard, the distance between the drain pipe and the center point, that is, the distance from the wall, is about 300 mm.

There are many options for the size of the toilet drain, generally 300, 350, 400 and 450 mm, according to the specifications of the toilet drain, there are 75 or 90, which refers to the nominal outer diameter, and the corresponding drain pipe will be different.

If the diameter of the drainage pipe is 110 mm, it is generally 300 or 400 mm with the wall, so you can choose 300 mm or 350 mm to ensure that the installation is in place in the later stage.

Reasons why the toilet can't be installed:

1. The toilet does not correspond to the size of the sewage pipe. It may be due to the incorrect selection of the drain pipe, and if there is a difference, the gap should not be too large.

2. Considering that the pipe is pre-embedded, it may also be necessary to consider the thickness of the wall tiles, and the size of the toilet outlet is 35 or 40, which needs to be combined with whether the toilet is drained under or after drainage. If it is a drainage, the wall to the pipe is about 36 mm, and the rear drainage can be directly connected to the wall and the drain.

3. The selected drainage pipes should also be within a reasonable range, otherwise there may be problems that cannot be installed. If the sewage pipe is not installed properly, it may also lead to the problem of blockage in the later stage, which will affect the use of the entire bathroom.
