"The workman was personable and understood the problem I had been having with the toilet backing up a couple of times during the preceding two weeks. I told him that another plumber had been out and recommended the septic tank be pumped. The work was completed in a reasonable amount of time and the lids were replaced as they had been previously. Everything works fine now."

Septic Tanks questions, answered by experts

Schedule annual inspections, test water pressure, and protect the pump from freezing temperatures.

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.

Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it’s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home. 

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.
