How To Unblock A Sewage Drain

How To Unblock A Sewage Drain

A blocked sewer line can adversely affect your drainage system and cause septic waste to back up in your home. Given that septic systems receive heavy use on a daily basis, they are susceptible to a variety of plumbing issues with the most common one being a blockage. 

Clogged drains manifest through the failure of bathtubs and sinks to drain quickly and efficiently. Clogging may also manifest through overflowing in the inspection gully and chamber. Tools like augers, drain rods fitted with a rubber plunger, hose, and rubber gloves are essential for clearing the system. You will also require adequate preparation and professional plumbing techniques as explained below.

Clearing the Drain-out Line

If you suspect that your sewer drain is not functioning optimally, the first place you should inspect is your drain-out line.

Clearing the Drain-out Line

If you suspect that your sewer drain is not functioning optimally, the first place you should inspect is your drain-out line. 

This line is normally fitted with a plug and can be located either in the garage, basement or around the foundation of your house. Open the cap but ensure that you step away to prevent the wastewater from spilling all over you. Subsequently, feed your auger into the drain until you hit the clog and allow it to run until the water level begins to decrease. It is advisable to let the auger run for a little while as there might be tiny pockets remaining, which could cause problems in the near future. 

After getting rid of the clog, spray high-pressure water into your drain pipe using a hose to remove lingering debris and to clean the auger. 

Locating the Blockage 

There are numerous access covers located between your house and the main sewer line. Open each one beginning with the closest one to your house and make your way towards the septic tank or cesspool. If the first chamber is empty, proceed to the next one until you find a chamber full of septic waste. A full chamber indicates that there is a blockage between that particular cover and the main drain. 

If the chamber nearest to the septic tank is full, it’s prudent to have the tank emptied.

Clearing the Blockage 

The first step of unblocking a sewage drain system is to fit a plunger on one end of your drain rod. Subsequently, try inserting the rod into the chamber. If the chamber you are working with is full, try moving the plunger around until you find the mouth of the pipe. Connect the rods, each at a time and continue plunging vigorously.

Remember always to work your tool clockwise as a counter move might cause the rods to unscrew and thus fall into the drain, which would lead to greater problems. If you encounter an obstacle that you cannot push through, replace the plunger with a corkscrew to break it down or simply grab and pull the obstacle out. 

Plumbing issues related to sewer systems are amongst the most dreaded and detested problems in domestic settings. With proper maintenance services aimed at reducing waste build-up in pipes and avoiding depositing materials that can block your drainage systems, chances for sewer line blockage can be significantly reduced. You should also have your septic tank inspected every two to three years to avoid plumbing emergencies and inconveniences.
