Septic systems are a vital part of many homes' plumbing systems, but they can be prone to failure if not properly maintained. As such, it is important to be aware of the signs that indicate your septic system needs service so that you can prevent costly repairs or even total replacement. One of the most apparent signs is an unusual odor coming from your drains and toilets. This could be a sign of methane gas buildup due to inadequate decomposition in the tank, indicating an issue with either the drain field or sludge accumulation in the tank itself. Additionally, slow draining sinks and toilets could be indicative of a clog caused by a buildup of solids within the tank that need to be cleared out or broken down by bacteria. Finally, pooling water around your property may also point towards septic problems as this indicates either a leaking pipe or blocked drainage field. Should any of these issues arise, it is best to call a professional immediately for assistance with servicing your septic system.
