Septic Tanks questions, answered by experts

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

Most cesspools are buried about 1 to 3 feet below ground. The cesspool itself can be between 8 to 10 feet deep, with an average capacity of 750 to 1,250 gallons. If you’re planning to fill in a cesspool, be prepared by knowing the size of your original tank so you can buy the appropriate amount of soil.

The average life span of a well pump is between 15 and 25 years, but a few factors can influence how long your well pump lasts. Excessive water demand and cycle frequency are the main causes of premature wear and tear. The well pump’s motor size as well as material and installation quality can also affect its life span.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

You can replenish good bacteria in your septic tank by adding three rotten tomatoes or 1/4 ounce of yeast every three months. Put three overripe tomatoes in the garbage disposal while running the faucet. Or pour 1/4 ounce of yeast in the toilet and flush it down. These are the best natural ways to increase bacteria in your septic tank. Septic tank additives are not necessary and may even cause harm to your septic system.
