"Leo went out of his way to meet my concerns about cost, collaboration with my neighbor, and how the fence would look. He submitted multiple bids giving me options as to how to do it and at what cost. He tailored his approach to my needs. His team was easy to work with. The team worked quickly, efficiently, and throughly. The fence looks great!"

Septic Tanks questions, answered by experts

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.

Signs that your well is dry include a decrease in water pressure, strange odors coming from faucets, cloudy, bubbly, or discolored water, and water that’s warmer than normal. Signs that your well pump is bad are similar, but you may also notice higher-than-average electric bills, strange clicking sounds, and faucets that spit or sputter.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.
