"Shane Flagg and his partner Doug (knowledgable retiree) are highly professional. Their work is efficient and complete. Erica Dole (in the office) scheduled the date/time quickly. I value the company for their work and their individual friendliness, and will welcome them back to add a 'riser' to the tank. Thanks to you all. Alan Baker"

"I was selling a 71 year old home and the inspection revealed a failing septic system. I had called another company as well as Bob snd had opted to use the other company which was local in Merrimack. Sadly I was told it would be 6 to 8 weeks. I could not wait that long since the house needed to be sold before winter. I called Bob and he began the same day! He explained he was also an engineer and could do the required septic design himself. He was able to have the entire job done in 2 weeks and we had a contract to sell before he finished. He was a delight to work with and I woukd recommend this company without any hesitation."

Septic Tanks questions, answered by experts

Septic drain fields should be at least 10 feet from the property line, though exact requirements vary by location. Some areas may require further distances, such as 25 feet or more, depending on soil conditions and local health regulations. This extension ensures proper wastewater absorption and prevents contamination of neighboring homes.

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

A well pressure tank typically lasts between 5 and 15 years. However, its lifespan can be influenced by several factors. High-quality, appropriately sized tanks tend to last longer, with some top-of-the-line models lasting up to 30 years. Regular annual maintenance, including inspections, cleaning, and prompt repairs, is crucial for extending the tank's life. Water quality also plays a significant role; water with high levels of sediment, minerals, or rocks can cause premature wear. Overworking an undersized tank can also limit its lifespan.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.
