Ask your local Plumber. That's why he went to school.
Install a one way check valve in the line from the house to the sewer.
Yes, it will do that. It is also unsanitary. You should have your floors professionally cleaned.
If the existing sewer line is lower than basement grade (does it go into the basement floor and out of the house?) you can just connect in to the existing drain. By code, sewer lines must have a slope of 1/4 inch per running foot, meaning that raw sewage will run AWAY from the main plumbing stack of the house. If the sewer line is ABOVE the level of the basement plumbing fixtures, you will need to purchase and install a pump check-valve, and tank to install any plumbing below the house sewer line. If you have any questions, contact a licensed plumber to find out the needs of your home.
The purpose of a basement sewer trap is to prevent sewer gases from entering a building. It functions by creating a water seal that blocks the gases from passing through the plumbing system and into the building.
A sump pump effectively diverts water from a basement to the sewer system by collecting water that accumulates in a sump pit, then pumping it out through a discharge pipe that leads to the sewer system. This helps prevent flooding and water damage in the basement.
You hire a plumber to put in a one way sewer drain valve.
Either they are on a separate sewer line and connect to the main sewer line later on or they sewerage is pumped by means of a machine into the main sewer line.
The purpose of a basement floor drain trap is to prevent sewer gases from entering the home. It functions by holding water in a U-shaped bend in the pipe, creating a barrier that blocks the gases from coming up through the drain and into the house.
You can easily find the main sanitary sewer trap by locating the fresh air inlet which is located no more then 4 feet behind the building house trap. It will be 1/2 the size of the main sewer but in no case less then 3" and 12" above grade min.
Frozen sewer out side
The sewer cleanout is typically located on the side of the house near the main sewer line.
To effectively eliminate sewer smell in your basement, you can try these steps: Check for any leaks or cracks in the sewer pipes and repair them. Ensure that all drains are properly sealed and functioning. Clean and disinfect the drains and pipes using a mixture of baking soda, vinegar, and hot water. Use a sewer gas odor eliminator or deodorizer to neutralize the smell. Consider installing a sewer gas vent pipe to improve ventilation and prevent odors from entering your basement.
