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: How deep is the average home water well?

• <div><p>Most home wells start at <b>100 feet</b>, and many go as deep as <b>200 or 300 feet</b>. </p><p>It takes quite a lot of water to meet the demands of showers, toilets, faucets, and appliances like dishwashers and laundry machines, and shallow wells struggle to provide this amount quickly. If you anticipate having high water usage in the future, it&rsquo;s often better to drill slightly deeper and give yourself a bit more water storage than you need.</p></div>

Q: How do I choose the right septic system for my property?

• <div><p>Consider site conditions, soil type, required capacity, and system designs compatible with environmental protection regulations.</p></div>

Q: How far from the bottom of the well should a submersible pump be?

• <div><p>A submersible pump should be at least 10 feet from the bottom of the well to minimize the risk of the pump drawing debris into the well water. Submersible pumps work best for wells that are 25 feet deep or less. If you have a deeper well, choose a jet pump instead of a submersible model.</p></div>

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>
