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.

Septic tank lids may or may not be buried in a yard. Most lids are buried at least 4 inches deep unless you have an aerobic septic system. Aerobic septic systems need frequent cleanings, about every four months, so it’s best to leave these lids aboveground for easier access. For buried lids, homeowners can use risers that make it easier to locate and access a buried septic tank lid.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

Drain fields often include three to five trenches that are 18 to 24 inches deep. The pipes connecting the drain field to the septic tank will be placed between 12 and 18 inches deep, and the field as a whole will be about 100 feet long.
