Septic Tanks questions, answered by experts

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.
