If you live in the suburbs or an unincorporated area, there’s a chance you rely on a septic system for waste management. The waste from your drains and toilet collects in the tank, and wastewater drains into the leach field before it is released into the earth. Solid waste sinks at the bottom of the unit, hence, the need to schedule routine septic tank pumping and maintenance. Call a professional septic company when you notice foul smells emanating from your drains or yard. At Septic Connection, we leverage extensive knowledge and proven techniques to inspect, detect, diagnose, and address the problem.

Causes and Solutions for Smelly Septic Tanks

What Causes Sewer Odors?

As mentioned, wastewater and solid waste are collected in the septic system. If you delay septic tank pumping, solid waste accumulates, causing clogs and backups. The last thing you want is to come home to a flooded home or yard, causing environmental damage and costly septic tank repair services. Foul smells are telltale signs of sewer damage and affect naturally occurring bacteria which break down waste.

Besides decaying waste in your pipes, methane gas is produced in the tank and causes nasty odors. Since methane is colorless, it can infiltrate your living spaces, rendering your home inhabitable. Another cause of sewer smells is leachate, the wastewater that drains from the tank into the leach field. If the effluent escapes, it affects your home’s comfort and increases the risk of bacterial or viral infections.

How to Avoid a Smelly Septic Tank

As a homeowner, you may be tempted to handle the problem alone. However, with the experience and equipment needed, you can avoid further deterioration and expensive septic tank repair services. Before attempting a DIY project, consult a reputable septic company. Here are tips to help you avoid such scenarios and maintain a healthy septic system.

Schedule a Professional Inspection

Sewer smells are telltale signs of damage, and the best way to prevent pungent smells is to schedule regular inspections. Whether you recently performed a septic tank installation project or have used the system for many years, routine checks ensure everything is in tip-top shape. In addition, inspections allow us to address other underlying problems before things get out of hand.

Septic Tank Pumping

Industry experts often recommend septic tank pumping every three to five years. However, there are several factors to consider, such as tank size, number of household members, and geography. If you need help to schedule pumping, contact the technicians responsible for the initial septic tank installation job. Professionals can inspect and account for critical factors before recommending a suitable pumping schedule.

Don’t Flush Everything

Septic systems handle human waste and toilet paper. Even if a product is labeled "Flushable" by the manufacturer, it doesn’t mean it is safe. Avoid flushing diapers, female hygiene products, napkins, and wipes. Most of these products are not degradable and often build up and clog the system.

Call Septic Connection for an inspection if you notice foul smells emanating from the drains, toilet, or yard. We provide top-notch septic tank installation, maintenance, and replacement services without breaking the bank.
