"Takes for ever to get a return a call. Also took a week to get someone out for repairs. They said they would reimburse me for septic repairs and it took over 3 months for that to happen."

Septic Tanks questions, answered by experts

Septic drain fields should be at least 10 feet from the property line, though exact requirements vary by location. Some areas may require further distances, such as 25 feet or more, depending on soil conditions and local health regulations. This extension ensures proper wastewater absorption and prevents contamination of neighboring homes.

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

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

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

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.
