Septic Tanks FAQs, answered by experts

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.
