1. Locate the sewer.
Before determining the location of the sewer, factors such as the size of the pool, the location and accessibility of pipelines and other equipment need to be considered. Then, use a drill to smooth the space around the pool to match the sewer.
2. Install the pipeline and backflow preventer.
Insert pipes of appropriate size into the sewer holes, which will extend to the kitchen sink and have any required elbows. When connecting pipes, make sure to use matching sealing rubber pads to ensure the isolation between water and air.
When installing the pipeline, the backflow prevention valve must be fixed in the pipeline, so that the wastewater cannot flow back into the submarine. The backflow preventer is usually a complex hollow sandwich wheel, which is easy to open itself when flowing.
3. Capture and treat wastewater
Small submarine wastewater can be directly discharged into the sea, but in large submarines, wastewater needs to be collected and treated. In this case, it is necessary to collect the wastewater into the reservoir and treat it by chemical treatment. The purpose of chemical treatment is to convert harmful substances in sewage into safe substances through chemical reaction, so as to avoid environmental pollution.
The installation of sewer in submarine kitchen needs professionals. Before installation, you need to understand the guiding documents and operate carefully in the implementation process.
