3 Warning Signs Your Septic Tank Needs Service Immediately

Shreks Septic Services • April 17, 2024

Septic systems play an important role in maintaining the cleanliness and aesthetics of your property by discreetly processing waste. Since these systems are usually out of sight, they tend to be forgotten until problems arise. Unfortunately, it often leads people to ignore early warning signs of necessary maintenance. Ignoring these can result in significant repair costs and pose health risks. In this blog, we'll identify the three critical indicators that your septic tank requires immediate servicing.

1. Slow Drainage 

An efficient septic system maintains seamless water flow, ensuring that waste leaves your home without any disruptions. If you start observing slow drainage, your septic tank might be signalling an issue. This problem might manifest in sinks, showers or other fixtures. 


Ignoring slow drainage can lead to more severe complications, such as sewage backups or even system failure. These outcomes are inconvenient and expensive to repair. Early intervention by a professional can mitigate these issues with minimal disruption to your daily life.

2. Foul Odours 

An unmistakable sign that your septic tank requires immediate attention is the presence of foul odours. When properly maintained, your septic system should be relatively odour-free. If you start noticing a strong smell of sewage around your property, it’s a clear indicator that your tank is either full or malfunctioning. 


These odours can also be a health hazard, exposing your family to harmful gases like methane. Such situations require urgent action to prevent health risks and environmental damage. A professional can help determine the cause of the smell with a septic tank inspection and recommend the best course of action.

3. Sewage Backups 

Perhaps the most alarming of all signs is a sewage backup. If sewage starts coming back up through your household drains, it is a definitive signal that your septic system is not functioning correctly. This can be due to a variety of issues, including a blockage in the system or an overly full tank.


Sewage backups cause significant damage to your home and pose serious health risks due to the bacteria and pathogens present in the waste. Cleaning up after a sewage backup is costly and unpleasant, emphasising the importance of regular septic system maintenance.
