The drain under the sink in the kitchen is clear, but the floor drain is flowing upwards. How to sol

The drain under the sink in the kitchen is unobstructed, but the solution to the upward backflow of the floor drain is as follows:

Preparation materials: pipe dredging agent, skin suction.

1. First of all, pour the sewer dredging agent into the floor drain, pay attention to a small amount many times.

2. Then pour boiling water into the floor drain, and use half a bottle before and after, but it is still relatively blocked.

3. But you can already see the blockages, the substances melted by the pipeline dredging agent.

4. The skin suction used to pass the toilet is dredged with the help of the suction of the skin suction.

5. Clean up the floor tiles next to the floor drain in the bathroom to ensure that the strength of the skin suction can be exerted as much as possible, pour water into the floor drain, and then continue to suck, and slowly dredge.

It depends on the specific situation: if it is a newly renovated house (here let's consider the home decoration), the sewer is unobstructed from the beginning of use, and the floor drain is returned upward, if the possibility of blockage from the floor drain to the sewer is ruled out, it must be that the floor drain is not set reasonably, such as the floor drain is too far away from the main drainage pipe, the drainage slope is too small, and there are too many turns, especially with a 90-degree right-angle tee. The most thorough solution is to change the floor drain directly above the main drainage pipe, the largest amount of drainage sources such as vegetable basins or washing machine drainage pipes and floor drain (main drainage pipe) at right angles or a little angle, if the worker technology can, try not to use tees, directly on the main drainage pipe holes, (the purpose of this is to increase the drainage section as much as possible, small debris is not easy to gather here), cement is laid, absolutely waterproof, and maintain more than 1% of the drainage slope.

Note that the main drain is the nearest pipe with the largest diameter that is connected to the main drain of the building (running up and down on each floor).

Different houses, the actual situation of the site is different, according to the situation of the site should be reasonable layout of the floor drain location, drainage pipe direction, drainage slope guarantee. Doing these things can solve the problem of leakage and backwater in the new home.

In the second case, if it has been used for a period of time, it will not be before, and now there is a floor drain and upward backflow, that is, the drain pipe is blocked by foreign bodies, and the solution is to find a dredge pipe to dredge a ha. And in daily life, maintain good habits and avoid draining hair, vegetable scraps and other materials into the drain.

If the sewer is not smooth, and the water will return from the floor drain when it is not completely blocked, the only way to deal with it is to dredge. But there are many ways to dredge, the soil method has hot water and caustic soda flushing, blocking the pool drain or floor drain drain, and then inflating from another drain, as well as a special flush sewer agent, etc., but the most reliable is the dredging machine.

You can first insert a glue hose into the drain, connect it to the faucet, and flush the pipe with water pressure, which will solve the problem because the pipe is somewhat blocked.

Not to mention theories.

Practical problem A good floor drain can solve the problem of backwater.
