Who's to blame for leaks in the toilet drain?
In the pre-renovation of the bathroom, the toilet sewer installation must be emphasized. The sewer pipe is an important part of the bathroom decoration. If the toilet sewer pipes are not installed in place, it will directly affect our lives. If the toilet cannot be put into use, it will not only affect the normal life sequence, but also may cause the whole house to smell bad, and it may also be affected by the building. Complaints from the main business. So, what is the installation method of toilet sewer pipes? What should be paid attention to? Don't worry, if you have this requirement, you might as well follow me to learn about the toilet plumbing.
Detailed method of installation of toilet sewer pipe
First, perform boost test after installation
The boost test is generally carried out at 1.5 times the water pressure, and there should be no water leakage during the test.
Second, a simple test method without pressure
1、Close the water main valve. (I.e. the water pipe switch on the front of the water meter)
2、Turn on the faucet for 20 minutes, make sure that there is no water and then turn off all the faucets.
3、Turn off the water inlet switch such as the toilet tank and washing machine.
4、Open the water main valve.
5、Twenty minutes after opening the main valve, check whether the water meter is moving, including moving slowly. If you move around, it is leaking. If you don't move around, you may be fine. It is recommended to conduct a water pressure test after construction. Generally, the pressure is 8 kg for 20-30 minutes.
Third, the direction of water pipes
The safest way to go to the top. If the pipeline goes underground, it is difficult to find the leak in time, and it is difficult to find the leaking place because the water pipe is buried. At this time, the huge loss is even more irreversible, and even seriously affects the friendly neighbor relationship; if the water pipe goes to the top, the water reform cost may be higher, but as a long-term investment, it is worthwhile. If the water pipe goes on top, the leak can be found in time, which is convenient for maintenance and small loss.
List of precautions for installation of toilet sewer pipes
1.Pass the roof to reduce the chance of man-made damage, and the joints and outlets of the hot and cold pipes must be parallel, usually the heat pipe is on the left and the cold pipe is on the right. The entire pipeline should avoid bending as much as possible, and should be removed from the circuit as much as possible. The position and slope of the pipe clamp should also meet the requirements. Each valve should be installed flat for future use and maintenance.
2.Distinguish the water inlet and outlet of the water heater, connect the main valve at the water inlet, and connect the pipe to the bathroom at the water outlet. After installation, open the valve to determine whether there is water leakage, and then install the faucet and flower in the bathroom. Just sprinkle.
3.If you can design a window in the bathroom, it’s best. If you don’t have this condition, in addition to installing exhaust fans, you must also avoid the occurrence of "wrapping". As a result, the moisture is trapped in the pipe and cannot escape, so the moisture in the bathroom becomes more serious.
Causes of blocked drain
1.If you accidentally fall into a foreign body or cause blockage due to installation errors, generally use a pipe dredging machine to directly dredge or replace the pipe；
2.Scaling will occur after use, making the inner diameter of the pipe thinner and affecting normal sewage discharge. This kind of dredging must use high-pressure water to clean the pipe, remove the dirt on the inner wall of the pipe, and expand the inner diameter of the sewage pipe.
Sewer dredging tool
1.Waterway dredging agent
Waterway dredging agent The waterway dredging agent in pipe dredging is the most common pipe dredging product currently on the market. It is widely used in hotels, restaurants, homes and other places to clear the blockage of sinks, washbasins, floor drains, bathtubs, and toilets. The water channel dredging agent will not damage the sewer pipes or damage the electroplating layer when used. When using it, first remove the accumulated water in the sink or sanitary ware, pour 50-100G waterway dredging agent into the sewer pipe, and rinse with plenty of water after about 20 minutes.
2.Hand-operated spiral steel wire
The most common tool used in pipe dredging is the hand-cranked spiral wire. The hand-cranked spiral wire is pushed down from the floor drain until it feels that there is a foreign object, then it is pulled up while shaking, blocking the hair and other objects. Will be screwed on the spiral steel wire, the pipe dredging problem will be solved. It is more convenient to dredge the drain pipe in the bathroom.
3.Baking soda and vinegar
In the pipeline dredging, if the blockage is caused by oil stains, you can use 20% soda water to dredge, or you can pour 1 cup of detergent into the blocked sewer pipe, and then pour 3 cups of hot water. Can not clear the sewer, you can pour another cup of vinegar. Soda powder and vinegar are more suitable for the following situations where the sewer pipe is slightly blocked. If the sewer pipe is seriously blocked, you can choose other more effective methods to dredge.
4.Other tools
You can choose according to the actual situation. The new type of PVC material, using a vacuum pump to suck up the water on it, and then pour concentrated vinegar, caustic soda, industrial vinegar, industrial alkali, etc., but it should be noted that it must not be mixed at the same time.
