How to install and replace the toilet floor drain replacement strategy

old residential areas often encounter the problem of floor drain odor, which is a headache. Generally, as long as you replace the old floor drain, you can solve the problem. In fact, you can also replace and install it yourself. Below, we will analyze the floor drain installation method in the form of pictures and texts

how to install and replace the toilet floor drain replacement strategy

installation and modification of floor drain

(I) installation of floor drain:

1 The floor drain should be equipped in advance according to the diameter of the drain pipe:

before buying the floor drain, you should know the diameter of the drain pipe. Now it is generally 50 PVC pipe, and the cast iron pipe should be larger. The drainage diameter of the selected floor drain should match the diameter of PVC pipe. Generally, the reserved holes for drainage are relatively large when the house is handed over, and they need to be repaired in the decoration. The drain outlet should be made according to the size of the floor drain. Don't repair the drain outlet first, and then choose the floor drain

2. Location of floor drain installation:

when installing the floor drain, try to install it as low as possible. You should first determine the location of the floor drain. The floor tile should be paved with a slope towards the floor drain. It is best to pave the tiles at the floor drain location. The floor drain should be installed in the middle of a brick, and the diagonal line should be opened to make it like this. In this way, it is best to drain water

3. Connection between floor drain and water inlet:

generally, the water inlet of floor drain can be inserted into the water pipe. See the appearance of the four prevention floor drain inserted into the water pipe

since the floor drain needs to be installed with a water seal core, it cannot be made too thin. If you add another 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 kind of structure is a general residence, there is no problem, because it is generally not a problem when the floor drain core is aligned with the water outlet and plastered with cement when laying bricks after the ground is waterproof. But this kind of floor drain is not suitable for the frame floor. Let's take a look at the sewer of the floor drain. There is no way to install it. If you put this floor drain on, it will swing back and forth unstable, and there will also be cracks. Once the sewer under it is blocked, its water will flow into the floor. Fortunately, there are not many such structural floors

when installing the floor drain, pay special attention to the bonding and sealing of the connection between the floor drain and the lower water pipe material. The installation should be tight, which can be sealed with professional adhesive or glass glue

(II) modification of floor drain:

1 Install floor drain:

there are two ways to add floor drain where there is no floor drain: one is to add high-level water pipe, which affects drainage; Second, it is troublesome to drill through the floor and re lay the sewer pipes, which requires construction downstairs

2. Refit the floor drain with the down pipe:

the automatic average cooling of the sample with the down arrival of the bathtub, the constant temperature nozzle or the water outlet of the washbasin are changed into floor drains for shower. The main problem is that such down pipes are generally 40 pipes, and now there are floor drains with small caliber on the market

3. Refit the thin floor drain:

install the thin floor drain (water seal 1-2cm), and the drainage is OK, but the water seal height is not enough, and the water will easily evaporate and return odor, so it is necessary to often fill the floor drain with water or cover it with a wet cloth to prevent the evaporation of water. The solution is very easy. Just change a built-in floor drain core, but try it, and some can't plug it in

4. Refit the old floor drain:

now many old floor drains at home have failed to seal. If you want to replace the floor drain, it is very troublesome, and there are many pipe diameters and specifications of the water free seal. You can directly insert it into the floor drain, which can play a sealing role. Take a look at the floor drain demonstration, open the floor drain, and insert the floor drain core

I think the biggest advantage of using this floor drain core is that you don't need to reinstall the floor drain in your old house. Just buy a core and insert it. In case the floor drain core is not suitable, just take out the floor drain core, which is about ten dollars. Choose the right one to fit various pipe diameters. See the picture

to explain again, the water sealing core can only be installed in the floor drain in the sewer pipe of 50, while the water free sealing core can also be installed in the pipe of 40, that is, the water in the wash basin. I used to exchange two floor drain cores on several floor drains. Only the waterless sealing core can adapt to various floor drains, and some other cores cannot be inserted tightly

maintenance and use of floor drains

many old-fashioned floor drains feel that the water is getting slower and slower after being used for a period of time. This is because a large amount of magazine dirt in the sewage is attached to the trap. If it is not cleaned often, it will lead to poor running water. But the old-fashioned deep-water seal floor drain is very difficult to clean. My method is to buy a slender screwdriver and bend my head, just like the fire hook used to poke the stove, and regularly dig in the water seal slot. Generally, I will dig out a lot of hair, but small impurities are not easy to clean out. Generally, I need to dig out with a small spoon

floor drains that can take out the floor drain core are relatively easy to clean. The floor drain only needs to rotate counterclockwise to take out the floor drain core, then rinse it vigorously in clean water for a few times, and then press it clockwise. According to different use conditions, it is generally cleaned every 20-60 days. Some built-in water sealed floor drains have strong self-cleaning ability, and it is also very convenient to take out and clean the floor drain core. Silicone water free floor drain can be basically free of cleaning. If these floor drain cores are damaged, it is also very simple to replace them with new cores

Lei Wen, director of the environmental protection department of the Department of energy conservation and comprehensive utilization of the Ministry of industry and information technology, also said that p> the leakage of general bathroom floor drains is mainly due to the lax installation and connection between the floor drain and the sewer pipe interface, which can not only be dedicated to producing satisfactory products for new and old customers, but also lead to leakage. The solution is to open the floor tiles around the floor drain, dig out the cement around 3cm deep, paint the joint of the pipe wall and the cement layer with rigid materials such as plugging spirit for local waterproof treatment, and conduct closed water test after drying. If there is no water seepage, it requires very high moisture content of the base course, grinding of the base course and primer treatment, which can be restored to the original state
