"Josh Wilder from Roth Home was excellent. He inspected my outdoor faucet to provide me an estimate to get it fixed. During his inspection he determined there was a blockage and had got the faucet operating with running water in a matter of minutes. He was very professional, punctual, and courteous."

Septic Tanks questions, answered by experts

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.

Well water is often assumed to be hard because of its high mineral content. Hard water can lead to mineral build-up in your pipes and appliances. You can manage hard water by installing a whole-house filter system. These systems can help extend the life of your water-reliant appliances like your hot water tank and dishwasher. 

Expect to take at least a day to drill your own well by hand. For a 500-foot well, this could take even longer, depending on the makeup of the soil and the terrain you are drilling through. Other factors include your physical strength and overall fitness level and the weather conditions you’re working in.

You should never park or drive on top of a septic field. Vehicles can weigh upwards of two tons, and this weight can put a lot of pressure on the leach lines in the drain field. Too much pressure on your leach lines may cause them to warp, crack, or completely burst. This is an expensive and very avoidable problem.

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.
