Septic Tanks questions, answered by experts

If your leach field becomes clogged or saturated, it can cause several problems with your home's septic system. The clog can cause sewage to back up into your home, leading to unpleasant odors and mess. A backed-up septic system can be a health hazard, particularly if the sewage starts to leach into the ground surrounding the leach field.

There are several ways to fix a saturated drain field, including cleaning out your septic tank, adding enzymes and additives to your drain system, and installing a larger septic system.

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

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.

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

Schedule annual inspections, monitor water pressure, and address minor issues promptly to avoid major repairs.
