Adequate care of a septic tank is a vital part of the upkeep for those whose homes are not linked to town sewers. Ensuring your septic tank is functioning is necessary in order to have an effective plumbing system and keep your property free of environmental threats. In many cases, septic tank care is not taken as seriously as it should be in households. 

When maintenance is neglected, it can lead to costly repairs or even contamination of the environment. Effective septic tank maintenance involves a range of practices, from regular pumping to judicious waste disposal. This comprehensive guide delves into the key steps for optimal septic tank upkeep, ensuring its longevity and preventing expensive repairs.

Pump the Septic Tank Regularly

The foundation of septic tank care lies in consistent pumping. The frequency–typically every two to five years–hinges on the tank’s size and household usage. Timely pumping prevents the build-up of sludge and solids, which is crucial for avoiding overflows and maintaining system efficiency. Without proper pumping, solids can build up in the tank, which can lead to problems like sewage backups and slow drainage. 

Inspect the System for Leaks

Regular leak inspections are pivotal in septic system maintenance. Warning signs include lush patches of grass or foul odours near the tank, signalling potential leaks. Professional inspections, especially during tank pumping, should include a thorough check of the tank’s integrity and its components, like baffles, for any damage.

Install an Efficient Filter

It is imperative to install an efficient filter in your septic tank system in order to maintain a strong plumbing system. The selected filter must be appropriately sized for the respective septic tank while also being capable of managing the amount of solids contained within the water. However, investing in a long-lasting filter with superior quality may reduce maintenance costs. It is also essential to keep the filter clean and free from debris. 

Effluent filters play a critical role in trapping solids, thus protecting the drain field from clogging. These filters require cleaning or replacement every few years, ideally synchronised with tank pumping, to maintain their efficacy.

Backflushing systems are an effective way to clear any solids that build up within the filter. Setting up these systems will ensure that any build-up is regularly cleared, helping maintain good performance and reducing the risk of blockages or other problems. It is important to check on backflush systems on a regular basis to make sure they are operating properly, as well as replacing filters at regular intervals.

Maintain the Drainfield

The drain field, a crucial septic system component, demands attention. Avoid driving or parking over it to prevent structural damage. The sooner you spot any issues and address them, the better. Check for standing water and cracks and holes regularly to find any problems early on. It’s also important to make sure that no roots are growing into the drain field, as this can cause damage to your system. Every couple of months, check your lines for any clogs or obstructions. This helps ensure that your septic tank runs optimally year after year with minimal maintenance required.

Be Careful With Cleaning Chemicals

Harsh chemicals can disrupt the bacterial ecosystem within your septic tank, which is crucial for breaking down waste. Choose septic-safe cleaning products, and minimise the use of substances like bleach and antibacterial agents to keep a healthy bacterial balance in the tank.

Toilets Are Not Garbage Cans

Wet wipes, paper towels, and sanitary products are non-biodegradable. Septic systems can be clogged and backed up due to these factors, causing costly repairs. Stick to flushing only human trash and toilet paper.

Properly Dispose of Waste

Responsible waste disposal significantly impacts the health of septic systems. Grease, oil, and non-organic waste should be kept out of the system to prevent blockages. These substances can accumulate, leading to inefficiencies and potential system failures.

Limit Household Water Usage

Water conservation can greatly benefit your septic system. Implement water-saving measures through efficient toilets, showerheads, and faucets, and spread out water-intensive tasks like laundry. This helps in preventing the septic system from becoming overwhelmed, thereby enhancing its efficiency and longevity.

Monitor and Reduce Solid Waste

Keeping an eye on the solid waste that enters your septic system is crucial. The use of kitchen garbage disposals should be limited as they can increase the amount of solids in the tank, necessitating more frequent pumping. Composting kitchen scraps is a beneficial alternative.

Avoid Harsh Drain Cleaners

Harsh drain cleaners can kill the beneficial bacteria in your septic tank. Opt for gentler, septic-safe alternatives or mechanical methods like plunging or snaking to clear clogs. Regular inspections and maintenance are also important to secure the proper functioning of your septic tank. We should consult professional services for regular cleaning and pumping.

Don’t Allow Fats, Oils, and Grease 

Pouring cooking oils or disposing of fatty substances down drains may seem harmless at the moment, but it can lead to significant long-term consequences for your septic tank. Fats and grease, when introduced into the septic system, can solidify and create blockages within pipes and the tank itself. 

These blockages not only impede the normal flow of wastewater but can also result in costly repairs and compromise the overall efficiency of the septic system. By adopting the practice of keeping fats and grease out of your septic system, you contribute to its longevity and smooth operation, ultimately saving yourself from potential headaches and expenses down the line.

Regular Professional Check-Ups

Make sure you hire a plumbing professional or a septic tank expert for regular check-ups. They can provide comprehensive assessments, addressing any emerging issues before they escalate into major problems.

Educate Household Members

Educating everyone in your household about what can and cannot go into the septic system is vital. This collective awareness and effort help in preventing unnecessary strain on the system.


Proper septic tank maintenance is a blend of regular professional care, mindful household practices and proactive measures. Septic systems can run more efficiently and effectively when homeowners follow these guidelines. When in doubt, always turn to professional plumbing services for expert advice and solutions tailored to your specific needs. Knowing the location and warning signs of septic tanks is important. If you notice any signs of distress, such as foul odours coming from the drain field, water pooling on the surface of the lawn or a slow-draining system, contact a professional right away.
