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.
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.
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
there is a blockage in your sewer line
An ejector pump is a tool used usually in basements when the sewer fails to flow beneath the basement floor. Basically the function of this tool is to pump water so that the sewer in the basement could work continually.
3" house (building) drain allowable. 4" building sewer line needed for house from sewer main.
A little more detail about the sitsuation would help. New construction, remodel, sewer outlet in the house to street or sewer outlet in house to main going out of house.
You must lift the sewage up to the place where the sewer pipe leaves the home. Most homes on level sites connected to septic systems have sewer lines close to grade level because these systems must be built shallow to perform. From the basement, sewage must be lifted up to the exit pipe usually inside the house. Plumbing drains in the basement (and this would apply to a single sink) are directed into a sump or plastic or concrete pit built into the floor of the basement inside a closet or near the outside wall. The sump is flush with the floor and has a sealed lid. In the sump is a grinder pump that grinds the sewage into a slurry and pumps it up to the sewer in a small diameter pipe where it combines with the other household sewage and flows by gravity into the municipal sewer or the septic system. Grinder stations can be installed by any plumber. They occasionally require maintenance, they make a little whirring noise a few minutes after you run water. Basement grinder stations are inferior to a gravity sewer. However many people are very happy with their basement grinders when there is no other alternative.
