6 Tips For First-Time Septic Tank Owners

1. Know Your Septic Tank
The important thing to remember is that it’s up to you to keep your septic system working well. Whether you take the DIY route, hire professionals, or do a bit of both, being familiar with installation and maintenance is key.
For instance, it’s really helpful to know where your septic tank is located and when it was last pumped. This info can save you a lot of time if issues like clogs arise, which you’ll want to address straight away.
2. Get Your Septic Tank Inspected Regularly
A common misconception among many homeowners is that septic tanks need to be inspected only when there’s a problem (to figure out the exact issue). But this isn’t true, as regular inspections are crucial in keeping your septic system optimally functional.
In hindsight, regular checks will help you detect septic tank problems like clogs before they become severe and inflict more damage. This, in turn, will save you a lot of money and time that would have otherwise gone for repair purposes.

Remember that these inspections should be extensive, including the rest of the septic system, pipes, and the drain field near the tank. Otherwise, you may encounter a wholly damaged septic tank system.
As such, an average household septic system should be inspected every 3 to 5 years, if not more frequently. So, book professional inspection sessions accordingly.
3. Don’t Choose Between Septic Tank Pumping And Cleaning
Many first-time septic tank owners think septic tank pumping and cleaning are the same and do only one. However, both these processes are equally important.
Over time, your septic tank will accumulate undissolved scum, sludge, and human waste, which can cause severe backups and leaks if not removed. Not only that, but you may also risk sewage flooding by ignoring this for too long. But getting the septic tank pumped regularly will help you avoid this, so don’t forget to schedule septic tank pumpings.
Septic tank cleaning, conversely, is a more elaborate process involving a thorough tank cleanup, starting from septic tank inspections to cleaning it inside out. Cleaning the tank is also vital after septic pumping, but not all septic service providers clean the tank after pumping. So, choose the right professionals for your home’s septic system.

4. Keep Your Septic System Safe From Trees
If you’ve moved into a new home and noticed trees growing near the septic tank, it’s in your best interest to relocate them. And if you’re designing your backyard from scratch, avoid planting trees near the tank and keep only grass cover around it.
While we’re all for looking after the environment, tree roots can be drawn to the moisture in your tank. They might end up breaking in, leading to cracks and leaks.
Besides, you may have damaged vegetation due to the flooding from the wastewater. And you don’t need us to tell you how expensive cleaning all the mess can become!
5. Ensure Proper Maintenance Of Your Plumbing System
Since all the water flowing down your sump pump drains will ultimately accumulate in the septic tank, keeping the plumbing optimally functional can take much of the load off the latter.
For example, you should clean the pipes regularly to prevent plumbing fixture backups and replace them immediately when required. Opting for energy-efficient appliances like an energy-star washer and low-flow plumbing fixtures would be best.
Likewise, equip your sinks with faucet aerators and bathrooms with high-efficiency toilets. Besides facilitating cost savings on water bills, they will ensure optimal water flow, meaning your septic tank won’t be under any excess strain at any time.
We’d also suggest avoiding running multiple loads in the laundry too frequently, as the water filled with soap and dirt will land in the septic tanks faster than it can process. Get the laundry room drain tested periodically to ensure there are no blockages. As for the kitchen sink, ensure that the garbage disposal doesn’t clog the main outlet drain.
6. Ensure Proper Garbage Disposal
One crucial thing to remember is that your outlet drains are typically meant for draining water and less viscous liquids. So, ensure that all solid waste, like soap, food scraps, plastic, hair, etc., doesn’t enter the drains and is correctly disposed of.
Also, strictly avoid flushing toilet paper, paper towels, coffee grounds, oil pesticides, drain cleaners and harsh chemicals down the drain. These can severely damage septic systems (or the sewer system) by disrupting the internal pH levels and hindering their ability to break down waste effectively.
The kitchen sink, in particular, should be kept free of cooking oil and sludge layers formed by cooking grease or animal fat. Never pour chemicals down the drain to free up clogs or dissolve internally corroded bits, as they will do more harm than good.
