Q: How big should a drain field be for my home’s septic system?

• <div><p>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&rsquo;s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the <a href="https://www.angi.com/articles/how-big-is-septic-tank.htm">right septic tank size</a> 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.</p></div>

Q: Do I have to add air to a well pressure tank?

• <div><p>Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it&rsquo;s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank. </p></div>

Q: Does well water damage pipes?

• <div><p>Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it&rsquo;s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home. </p></div>

As a general rule, you should have 1 square foot of drain field size 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.

There are a lot of issues that can cause a septic tank to collapse.
