Installation method of sewage pipe Matters needing attention in installation of sewage pipe

In the whole process of home improvement, the installation of sewer pipes is a matter of great concern to everyone, especially the kitchen and bathroom. So what are the installation skills of sewer pipes?

Installation skills of kitchen sewer pipe

There are two main types of kitchen drainage: downward drainage and lateral drainage.

Drainage: Drainage means that the drainage outlet is on the ground, the sewer pipe passes through the floor vertically, and the pipe leads directly to the downstairs. I am used to installing a return bend at the bottom, so that if there are other launches, I can use the return bend.

Side drainage: The side drainage outlet is located on the main kitchen pipeline. Above the ground, a part of the sewer pipe leads horizontally to the main pipe. There is a return pipe under the building. If a return pipe elbow is installed on the floor, it is double deodorization, while the side drainage means that the sewer pipe is horizontally connected in the main sewer pipe. Generally, only one return pipe elbow can be installed.

One kind of launching is to connect a 45-degree elbow to the horizontal pipe, and then connect half a return elbow, but pay attention to the fact that this return elbow must be triangular and round, which is not easy to connect, and then connect to other pipes. Generally speaking, the side drainage is not as smooth as below.

Installation method of toilet water pipe

1. Generally, there are hot and cold water pipes in toilets, and PPR pipes are mostly used. The distance between hot and cold water pipes should not be too close.

2. All bathroom pipes come from the roof, which can reduce the chance of man-made damage. The interface and outlet of hot and cold pipes should be parallel. Generally, there is hot water on the left and cold water pipe on the right.

3. The pipeline line design should avoid bending.

As far away from the track as possible. Finally, the position and slope of the pipe clamp should also meet the requirements, and the valves should be installed smoothly to facilitate future use and maintenance. Both cold water pipe and hot water pipe are plugged into the wall. Check the groove depth when slotting, and the hot and cold water pipes cannot be in the same groove.

5. When installing the water inlet and outlet of the water heater, the water inlet valve and air inlet valve must be considered and installed in corresponding positions.

6. When installing hot water pipes, pay attention to the difference between the water inlet and the water outlet of the water heater. The water inlet is connected to the main valve, and the water outlet is connected to the bathroom pipeline. After the installation is completed, first open the valve to ensure no water leakage, and finally install the faucet and shower in the bathroom. The height of shower pipe is between1.8m-2.1m.

Matters needing attention in sewer installation

1. The hot water pipe is too close to the wire: water and electricity are absolutely incompatible, so it is absolutely not allowed to lay the waterway and the circuit on the ground at the same time. If something goes wrong, it will be extremely dangerous The floor of the house upstairs will overlap with the electrical appliances on the roof downstairs. If something happens, the consequences will be very serious. In particular, the hot water pipes should not be too close to the wires. The wires, pipes and hot water pipes all emit heat and are closely connected, which is easy to be deformed by heat and cause short circuit.

2. Water pipes are not horizontal or vertical: Water pipes must be laid horizontally and vertically, so that subsequent workers can master the direction of the pipes during construction and avoid perforation. In addition, before construction, check whether there are signs such as "No drilling in the line" on the ground to avoid damaging the underground pipeline. In addition, attention should be paid to keep water in the pipe during construction, and once it is broken, problems can be found in time; If the main valve is opened at the completion of the project and the pipeline is found to be leaking,

The damage will be even greater. After learning the above knowledge, do you think you have a thorough understanding of this content now? I hope these knowledge of sewer installation methods will help you.
