Basement sink
Not all basements are equipped with a drainage system. This can be a problem if you are planning on adding a laundry room or bar in your basement. Here are a few steps on how you can do it:
Pumps
One easy way to create a drainage system is by installing an above-ground water pump.
Outside drain lines
If your home has a drainage system that is placed under the basement floor level, then you can connect this one with the basement drainage. This involves a lot of work and the modifications should be done by a professional. You will need to remove large parts of the basement wall.
Basement sump pumps
You can also use an exterior sump pump or a storage tank with an ejector pump. These pump will evacuate the water to the existing drainage pipe lines. This is the perfect solution for basement bathrooms, because these systems can handle solid waste.
