"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."

"Excellent. I called Ferris Plumbing on a Thursday afternoon and left a message. Matt returned my call the next morning. After I explained the problem, Matt said he would try to get to me that day (Friday), but he may not be able to. Meanwhile, he suggested not using that toilet. He called later that day and said he couldn't make it, but would be able to on Monday. He called me on Monday morning to confirm that he would be coming and gave me a estimated time of arrival. Matt wasn't able to come himself, but two of his plumbers arrived mid-morning. I explain all of this because Matt's communication was OUTSTANDING. I always knew the status and I knew he would be arriving as soon as he could. His two plumbers were also excellent and efficient. They replaced the toilet flange and gasket, and remounted the toilet without needing to disturb the downstairs ceiling. I should mention that the toilet is the original installation of 48 years ago. The original gasket was completely disintegrated to the point that only few small fragments of it were left. They were also very careful to protect the carpet just outside the bathroom by placing a drop cloth to protect it. Their service and work was EXCELLENT. We are considering remodeling that bathroom and Ferris Plumbing will certainly be our first choice to do the work. I highly recommend (Matt) Ferris Plumbing."

Septic Tanks questions, answered by experts

Yes. A septic tank riser is meant to replace a septic tank cover—concrete, metal, fiberglass, or otherwise—while still allowing easy access to the opening of the tank. Just as you would need to be mindful of the septic tank lid when it comes to mowing the lawn or other yard usage, you’ll have to be cautious not to damage or otherwise disrupt the septic tank riser.

All municipalities in the U.S. require a permit for septic tank installation or septic system alteration, and the permit will usually cost between $450 and $2,500. Some municipalities also require permits for septic system repair. You’ll either need to contact your local building department or your septic tank company to ask if this is necessary before carrying out the work. Permits are not typically required to have your septic tank pumped, so provided your septic company is licensed, you can move forward with the work as needed.

A septic tank with a 1,500-gallon capacity is good for larger homes with up to 6 or 7 bedrooms. The average home can go with a smaller tank, about 1,000 gallons, which supports a home size of up to 2,500 square feet, or a home with about three bedrooms.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.
