Septic Tanks FAQs, answered by experts

A new water well pressure tank costs $300 to $500. If you choose to hire a plumber for the job, expect labor to cost $125 to $200. If the tank is difficult to access, labor will cost more. Diaphragm and bladder well pressure tanks have similar costs. One-compartment well pressure tanks are less costly, but they have a higher chance of waterlogging. Larger pressure tanks cost more and hold more water, but they don’t increase water pressure.

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 average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

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.
