Picking New Parts for Your Septic System Based on Need

The way a septic tank and system are designed, they’re meant to last for many years at a time. This is both good – and bad. 


The good thing about the design of septic components is that once you’ve installed the system, as long as you stay up on routine maintenance and inspections, you’re unlikely to have major issues or need replacements often. The systems themselves are designed to work without careful or close monitoring, so you have to do very little. 

The bad, though? Since everything wears at a different pace, you’ll never know when you’re going to need to upgrade or replace a part. Anaerobic systems rely on fewer moving parts than aerobic systems, but both of them will, at some point, require maintenance.

Here’s how to choose the new parts for your system based on need. 

Commonly Replaced Septic Tank Parts

Septic tank lids and covers: Some of the only visible components of your septic system, these are more susceptible to the elements than the parts that are constantly buried. Septic tank covers are made out of multiple materials from plastic and metal to fiberglass, and it’s important to choose the right one for your system. There are even concrete septic tank lids available, too. 

Septic tank aerators: This is one of the most commonly replaced parts within a septic system, and for good reason. Components like the JET 700 septic aerator are constantly in motion, agitating the water within your septic holding tank in order to promote bacterial growth and speedier breakdowns of the solids. The septic tank aerator is designed to withstand prolonged use, but when items that aren’t meant to be introduced into the system – like plastics, cloth and paper – find their way in, sometimes they become tangled, which can burn the motor out.

Septic tank pumps: The pump is responsible for maintaining water levels within the system, and like the aerator, it’s almost constantly running. This use means that it’s more likely to wear down as time passes, resulting in the need for replacement. There are different sizes and types of pumps for different septic tanks and systems, so be sure to choose one that is the correct size and has the capability to move enough water through your system. 

Septic tank filter: Also called the septic tank baffle, the filters are responsible for moving water into and out of the system in the correct places. The intake filter may get stuck or jammed due to the introduced solids, and the outflow filter has the same potential for issues – though this happens much less often. If there is a problem with your septic tank filter, things won’t work as they should, and may lead to issues down the line. 

Don’t Choose Alone – Use Professional Help! 

It’s not uncommon for homeowners to be in the dark when it comes to knowing what their septic system needs the most. Luckily, there are ways to ensure that when you buy new septic system parts, they get ones that they can actually use. Visiting websites for septic services, consulting with septic professionals, and even browsing forums where people give advice and directions are all recommended – at least until you’re more comfortable with what you’re doing!
