Installation method of sewer inlet valve

Sewer is an important pipeline system, which is responsible for discharging waste water from toilets, bathrooms, showers and kitchens in houses and buildings. In order to ensure the normal operation of the sewer, it is necessary to install a water inlet valve to prevent sewage from flowing back and forth. The following is the installation method of sewer inlet valve for your reference.

1. Ready

Before installing the inlet valve, you need to prepare the required materials and tools. The required materials include water inlet valve, anti-pollution sleeve, pipeline glue, flame sterilizer, etc. The required tools include wrenches, pliers, chainsaws, etc.

2. Select the valve position

First, you need to choose the position of the inlet valve. Generally speaking, we will install a water inlet valve at the lowest point of the sewer to prevent sewage from flowing backwards. At the same time, the inlet valve should be as close as possible to the main water pipe of the house or building to facilitate the opening and closing of the valve.

3. Install the valve

When installing the valve, it is necessary to connect the flange of the valve with the sewer pipe. This process requires the use of pliers or wrenches to tighten the valve. After the installation, check whether the connection between the valve and the pipeline is tight, so as to ensure that the sewage will not leak.

4. Install anti-pollution sleeve

After the water inlet valve is installed, it is necessary to put an anti-pollution sleeve on the valve. The function of this sleeve is to prevent sundries and dirt from entering the sewer from the valve and keep the sewer clean and unobstructed.

5. Seal the valve

After installing the inlet valve, it is necessary to seal the joint between the valve and the sewer with pipe glue. If the pipeline is long, joint connection can be used for maintenance and cleaning.

disinfect

After installing the water inlet valve, it is necessary to use a flame sterilizer to sterilize the pipeline. This process should be done well in advance to ensure the sanitation and cleanliness of the sewer.

In a word, the installation of the sewer inlet valve is very important, which can ensure the normal operation of the sewer and prevent the sewage from flowing backwards. Correctly installing the sewer inlet valve can provide a safe, hygienic and reliable living environment for our families and buildings.
