Bathroom renovations in the basement are not the same as renovating your lavatory above the grade. When you are above the grade, the gravity is assisting with moving the waste down. However, when you are below the grade the gravity is not always on your side. Some homes have the sewer lines run deep underground. In such cases, connecting to the sewer line is easy. But what if the bathroom is below the sewer line? Let’s look at how you can resolve this problem.

There are few options to resolve the above issue and we shall discuss some of the more popular ones here. One option is to install an up-flushing system to pump the waste up to sewer line. Some of these up-flushing systems can also connect to the bathroom shower and other drainage to pump to those to the sewer lines. Although the up-flushing system is expensive, you do save on installation cost as you do not need to break the concrete slab. The pumping mechanism is generally hidden inside or behind the toilet.

Another option is to use a sewage-ejector system which is similar to a small septic tank that sits below your bathroom. Your toilet shower and washing machine can then drain to this tank. These storage systems also house a discharging pump that can discharge the waste to your home’s main sewage line.

It is therefore important to learn about the location and depth of your sewage lines before starting a bathroom renovation project in your basement. You could save time and money by determining a head of time what option is best suited for your home.
