How to increase the floor drain in the bathroom?

First, the bathroom floor drain installation

1. In many cases, the reserved hole of the drainage pipe of the real estate developer is relatively large when handing over the house, so when decorating the reserved hole of the drainage pipe, it should be exactly the same as the floor drain bought back. Under normal circumstances, the aperture of the floor drain grate should be controlled between 6 and 8 mm, which can prevent the entry of dirt such as hair, sludge and sand.

2. When installing floor drain, multi-channel floor drain is a product developed in recent years. A main body usually has 3 to 4 water inlets (to receive washbasin, bathtub, washing machine and floor drainage). This structure not only affects the drainage capacity of the floor drain, but also does not conform to the actual design situation. Therefore, when installing leakage, there should not be too many water inlets for multi-channel floor drains, and only two (floor and bathtub or floor and washing machine) can fully meet the needs.

3. If a floor drain is to be installed, it should be installed in a place where there is no floor drain. It is usually installed in two ways: one is to punch holes in the floor and rearrange the water pipes; Another method is to raise the ground and drain the pipeline.

Second, the toilet floor drain waterproof practice

Floor drain is the part where the ground drainage is concentrated, which is prone to leakage. Moreover, the cast iron floor drain has a big bottom and a small bottom, and the outer surface is in contact with concrete. Due to the shrinkage of concrete, cracks are easy to occur, which leads to water leakage around the floor drain. Generally, holes should be reserved in the floor of submerged structure, and then floor drains should be installed. After the floor drain is installed and fixed, the details should be waterproof.

Waterproof project of toilet, details of waterproof practice of floor drain of toilet:

1, determine the elevation of floor drain, install fixed cushion, find slope, lay leveling layer, lay waterproof additional layer around floor drain, lay waterproof layer for water storage, and lay floor drain grate on the surface; Pouring plate hole:

2. After the floor drain and riser are installed and fixed, clean up the concrete and stones around the hole, then support the bottom formwork, water and wet it, pour C20 fine stone concrete mixed with expansion agent, and tamp, block and smooth it;

3. Find a slope and leave a groove: find a slope on the ground, and find a slope of 1%~2% from the leveling layer to the floor drain. The drainage slope of the floor drain 50mm outward is 3%~5%, and a groove of 20mm×20mm is left around the top of the floor drain.

4. Groove filling: the groove around the upper mouth of the floor drain is filled with sealing material, and a coating of matrix reinforced material is added to attach a waterproof layer. The coating depth of the additional layer should not be less than 50mm, and then waterproof coating should be applied according to the design requirements;

5. Water storage test: Do a good job of water storage test, and observe that there is no leakage as qualified;

6. Waterproof tray: In order to solve the problem that the cast iron floor drain has a big bottom and a small bottom and is not well combined with concrete, a waterproof tray can be added to the original leaking place to improve the waterproof quality of the floor drain.

Floor drain is a small device at home, but it also plays an important role. If the floor drain at home is blocked, it must be a very annoying thing The stagnant water on the ground can not be discharged smoothly, which brings a lot of trouble to the normal use of toilets and kitchens. So how to solve the floor drain blockage?

The floor drain is blocked-the reason

1, sundries: the floor drain at home is blocked. It is very likely that some small debris fell into the floor drain and blocked it, resulting in the sewage not being discharged normally. For example, the kitchen floor drain is blocked, which may be caused by some food residues in the kitchen; The biggest blockage of the bathroom floor drain may be that our falling hair will block the floor drain, so in daily life, don't think that it doesn't matter if small debris falls into the floor drain, so it should be removed in time.

2. Building materials: If the floor drains at home are in good condition, and there is a cover on them at ordinary times, it is likely that some decoration materials were accidentally dropped into the pipeline during the decoration process, and they were not cleaned up in time, resulting in the blockage of the floor drain and the inability to drain.

3. Main pipeline: The main drainage pipeline of the external wall connected with the floor drain is blocked, which leads to the water in your house not being discharged. You need to ask your neighbors upstairs and downstairs if there is any similar situation of blocking the floor drain. If there is a blockage, it means that it is the problem of the main pipe outside.

The floor drain is blocked. Clear it.

1, soda vinegar dredging method: first pour half a cup of cooked baking soda powder into the sewer, then half a cup of vinegar. After soda reacts with the acid in vinegar, the oil attached to the pipeline can be removed.

2. Log dredging method: first, insert a log with a diameter close to the drain in the water pipe, put a certain amount of water in the pool, and twitch the log up and down quickly without interruption. Under the action of suction and pressure, the dirt in the pipeline will be washed away.

3, water pump dredging method: when the local sewer is blocked, you can insert the hose of the water pump into the sewer, and then put a small amount of water, constantly pumping air into it, the pipeline can be dredged.

4. Caustic soda dredging method: If the sewer pipe is blocked, you can buy some caustic soda from the market, put it in the sewer pipe, and then pour some hot water. When caustic soda meets hot water, chemical changes occur when caustic soda meets hot water, the temperature rises rapidly, and the grease in the pipeline melts and is discharged with water, thus solving the problem of sewer blockage.

5. Dredging agent: supermarkets sell "pipes" (liquid and bottled) to clean up the blockage of such pipes, and pour an appropriate amount according to the degree of blockage. Pay attention to the instructions before buying, because some kinds of pipes are for metal pipes, and plastic ones can't be used.

6. Biological dredging method: put a small yellow owl or loach into the sewer pipe, then add some irritating things such as washing powder or salt, cover it, and dredge the pipe through the biological characteristics of the yellow owl.

7. Dredger: Now many stores and supermarkets sell a kind of pipe dredge, which is convenient to use and not very expensive. You can buy a dredger like this to dredge.

8. Professional dredging: If you can't solve the problem of floor drain blockage of sanitary ware, you can only ask the property or special pipeline dredging personnel to dredge it.
