Things You Should Never Flush Into a Septic Tank

Septic tanks play a crucial, yet underappreciated role in the running of any property, from homes to business and commercial premises, ensuring that wastewater is drained from the home and broken down, whereupon the impurities and excess water are filtered into the soil to serve as nutrients. Despite the robust nature of the tank, there are certain materials that should not be flushed into the septic tank.

Grease and fat

These can cause a number of problems for the drainage systems in your home. Pipes do not deal with grease and fat well, so you may end up with blocked drains, but in terms of the septic tank, it can also block the perforated holes in the pipework, which means that the wastewater cannot be drained, or ‘percolated’ into the soil.

Things You Should Never Flush Into a Septic Tank

Antibacterial products

We know that antibacterial products are designed to kill bacteria, which is all well and good when it comes to cleaning surfaces in our homes. However, these products, like hand washes, can also kill good bacteria, which perform a key role in the function of your septic tank; breaking down solid waste. Without these bacteria, the septic tank cannot do its job properly, and there is a serious risk of blockage.


Nappies are not biodegradable, which means they need to be put in the bin, not flushed down the toilet. If they are flushed down the toilet, they will will cause the most unpleasant of blockages in your septic tank.


Unfortunately, we can’t control when it rains and does not rain. However, we can control whether or not our septic tank is overloaded by rainwater. Simply avoid connected any rainwater pipes or gullies to the tank.

Cotton buds

As small as they are, cotton buds can cause big problems for your septic tank if they are flushed into it. Like nappies, they are not biodegradable, which means if you flush them down the toilet, you might be heading towards a very, very unhygienic situation.

If you take care to only flush the right materials into your septic tank, then you will avoid all these issues and not have to worry about any waste coming back to haunt you. However, if you do encounter a problem, it is important that you contact professional assistance immediately.
