Septic Tanks questions, answered by experts

The cost to drill a well varies, but the national average is around $5,500 for a 150-foot well. However, prices can vary significantly based on location, well depth, and other factors, so it's best to research potential fees to get a more accurate cost assessment for your area.

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

You may notice a septic smell in your yard after it rains if groundwater is entering your septic tank and causing it to overflow. If you experience septic odors after rainfall, contact a licensed plumber. They can construct a drain to redirect rainwater away from your septic tank. 

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

The average life span of a well pump is between 15 and 25 years, but a few factors can influence how long your well pump lasts. Excessive water demand and cycle frequency are the main causes of premature wear and tear. The well pump’s motor size as well as material and installation quality can also affect its life span.
