Can the water in the tank be drained slowly?
In bathroom design, the design of floor drainage is very important. Reasonable drainage design can effectively prevent poor water flow and avoid the occurrence of water accumulation problems. If the water drainage of the platform is slow, it will not only cause inconvenience in use, but may also lead to hygiene problems. Decoration Guy etc. discuss the main reasons why water drains slowly from the floor, and provide a series of simple and effective DIY solutions to help you deal with this problem.
Key factors for floor drainage
Good floor drainage design includes the following key elements:
Slope design
The floor should have a certain slope so that water can flow naturally to the drain. If the slope is too small, water will not flow smoothly and water will accumulate on the ground, increasing the risk of mold growth; if the slope is too large, it may cause discomfort when standing. Therefore, the height and slope of the platform should be accurately calculated during design to ensure that water can be effectively drained.
Air-tight design
The air trap is a water storage seal installed between the drain outlet and the sewage pipe, mainly used to prevent odor from entering the room. Common types of air barriers include U-type air barriers and bottle-type air barriers. These devices are usually equipped with an "anti-siphon air valve" that can balance the air pressure and prevent the water seal from being sucked away by the air pressure generated during flushing.
Waterproof layer constructionThe waterproof layer is an integral part of the floor drainage design and must be ensured to be leak-free. The waterproof material should be evenly applied between the floor and the wall, and fill the gaps between tiles. After applying the waterproofing layer, construction workers will conduct a water storage test to confirm that there are no leaks.
Drain outlet selection
The setting of the drain outlet needs to consider the overall layout of the bathroom, and the appropriate drain outlet model should be selected to ensure drainage efficiency. In addition, the diameter and design of the drain outlet should be able to withstand the water flow in the bathroom to avoid blockage caused by too fast or too slow water flow.
Reasons for slow water drainage from the floor
Dewatering siltation
When using the bathroom, hair, soap scum, sebum and other debris will flow into the drain pipe with the water flow. Long-term accumulation will cause the drain outlet to be blocked. This not only affects the drainage speed, but may also produce odor.
Prevention method: Install a filter at the drain outlet and clean up debris regularly to reduce the possibility of blockage.
Dirt accumulation
Ingredients in shower gels and shampoos can combine with skin oils to form a sticky residue, especially inside pipes. If not cleaned up promptly, this residue can harden over time and seriously affect Drainage efficiency.
Prevention method: Flush the drain pipes regularly with detergent and check for dirt accumulation.
Trachea blockage
The blockage of the air trap will affect the air pressure balance of the drainage, resulting in poor water flow. This is usually caused by debris or dirt building up inside the trap.
Prevention method: Check the bottom box of the air separator regularly, clean the sediment and ensure it is unobstructed.
Insufficient floor slope
If the slope of the floor does not meet the standard, water will not be able to drain smoothly and may even accumulate. The ideal slope should be between 1% and 3%.
Handling method: If the slope is found to be insufficient, professionals may be required to redesign or trim the floor to achieve optimal drainage.
Waterproof layer problemIf the waterproof layer is damaged or improperly designed, water will seep into the ground and affect the normal operation of the drainage system.
Handling method: Check and repair the waterproof layer in time to ensure its integrity.
DIY solution
Check the water and air separation
Remove the floor drain and check the air trap to see if it is clogged with hair or dirt. If present, clear these obstructions to improve water drainage.
Use ditch vine
If there is no blockage in the air trap, you can use a cane to aim at the channel opening and continue to rotate the wheel until the blockage in the channel is stirred out. Next, stir the wheel in the opposite direction to retract the extended drain cleaner, and then rinse it with plenty of clean water.
Using a toilet pump
If the drain clearing rattan is not long enough to clear the blockage, you can use a bowl pump or vacuum pump to add pressure to help loosen the dirt and push the blockage to the main channel.
Add baking powder
Baking soda can effectively dissolve grease blockages. Mix 200 grams of baking soda with a large amount of hot water and pour it into the drain to effectively clear the blockage.
Replace the air-tight floor drain
If the drainage problem is caused by a gas-tight floor drain, you can consider replacing the gas-tight floor drain with a common floor drain to improve the drainage effect.
