"They responded immediately and fixed the problem. While there we had them address a few other issues and they fixed them immediately and did not take advantage of us. We also had them come out in March 2013 because we were told that we needed a new well expansion tank by another company. They were honest and showed us that we did not need another tank. The tank was working fine. I would recomend these guys. They are good.

Septic Tanks FAQs, answered by experts

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.

If you notice a septic smell in the house, you can either call a septic system repair company or a plumber. These professionals have the proper licenses and equipment to investigate the pipes and septic tank while keeping your family safe from sewage gas exposure and raw sewage leaks. They will be able to find the problem as soon as possible and get it fixed so that your home can get back to smelling fresh again.
