sewers can drain the sewage used in life, which has a great effect on home life, but many people encounter the situation of sewer blockage in life, do not know the reason of sewer blockage. when encountering the blockage of sewer, people all hope to solve the blockage and restore the smoothness. let's see the simple and practical method of the blockage.
1、 causes of sewer blockage
1. closestool slight obstruction: generally it is the closestool obstruction formed by toilet paper or towel, sanitary napkin, dishcloth, etc., which can be unblocked by using the pipe dredger directly or by simply unblocking things.
2. toilet hard object blocking: when using, it accidentally falls into the bottle cap, soap, plastic brush, comb and other hard objects. this kind of small block can be directly dredged by using a pipe dredger or a simple dredger. it is necessary to open the toilet to dredge when it is severe. this kind of situation can be completely solved only by getting things out.
3. toilet aging and blocking: the toilet has been used for a long time to avoid scaling on the inner wall of the toilet. when it is severe, it will block the air outlet of the toilet and form slow toilet water. the solution is to find a vent to scrape away the dirt so that the toilet water can be dredged.
4. toilet device error: the main reason is that the outlet at the bottom is not aligned with the lower nozzle, the screw hole at the bottom of the toilet is completely sealed, which will cause the toilet water not to be dredged, and the water level of the toilet water tank is not high enough to affect the flushing effect.
5. change squatting pit to toilet: when some old houses are built, squatting pit is installed. the u-shaped waterproof elbow is used at the bottom of the sewer pipe. when the toilet is formed again, the bottom elbow can be changed into a direct bend. if it can't be changed, it is necessary to do a good job of bottom backwater bending before installing the toilet. do not let the cement or tile fragments fall into the device.
2、 a simple and practical method to block and dredge sewer
1. water channel dredger, which is a very good product to dredge the drain blockage at present, is especially useful for the blockage caused by hair, greasy, paper, etc. widely used in restaurants, hotels, families and other basins, bathtubs, floor drains, sink, toilet blocking dredge. do not damage the water pipe (including pvc pipe), do not damage the electroplated layer.
2、若曾用镪水倾儿又请工入用铁枝经过而稍畅,但后来又不去水,则不适合再用铁枝,恐防 腐蚀过之水渠被通穿。可改用粗藤条,藤条头可钉十口八口寸长铁钉,一面伸入一面打转搅动,把杂物搞 松,然后用浓饶碱溶液灌入,再把藤条推动拉出,如是继续屡次,当可收效。除了粗藤外,也可往五金铺 买绷簧通渠器,带来的作用也会比较好。
2. if you used to pour water and asked workers to use iron branches to pass through, but later did not remove water, it is not suitable to use iron branches again, for fear that the anti-corrosion channel will be penetrated. crude cane can be used instead. the head of the cane can be nailed with ten eight inch nails, which can stretch in one side, rotate and stir, loosen the sundries, then pour in with concentrated alkali solution, and then push the cane out. if it continues for many times, it will be effective. in addition to crude rattan, you can also buy a tension spring channel opener from the hardware shop, which will bring better effect.
3. if your sewer is made of new pvc raw materials, you can first use a vacuum pump to suck up the water on it, and then fill with concentrated vinegar. maybe industrial vinegar, caustic soda and industrial alkali can all be used, but don't mix them, just use one. if you don't know, maybe you're not sure, maybe it's old-fashioned iron pipe, then you can only use the weak acid test of vinegar grade, and you can't use the above methods. fill these things in the future, about 3 hours will work, if there is no response, then you can only find a professional dredging team for forced dredging.
4. go to the market and buy a 2m long taut spring steel wire pipe to dredge things. make a 10-20 degree bend at 1-2cm above its head. i will dredge the water inlet and outlet back and forth, and wash it with water. then i can dredge the toilet.
as for the reasons of sewer blockage, if we want to solve the problem as soon as possible, it is better to try the simple and practical method of sewer blockage introduced in this paper. if you try these methods and still can't solve the problem of sewer blockage, remember to seek the help of professional companies or individuals.
