He was purposeful about doing the right thing even when not winning installation contract, execution of which he in in fact supervised. In a business which includes its share of uneven performers, Schofield’s competence is a stand-out."

"Don Morris is an amazing individual. I've been calling contractors for my septic system and for other work for weeks. He is the only one who consistently returns calls. Additionally, he is punctual and direct. He doesn't pull any punches. His pricing is amazing, and a very pleasant surprise. He and his crew showed up on the agreed upon date, and they went right to work. Within three days, they had everything finished, including delivery of a truckload of loam. I couldn't be happier with the work they did. I wouldn't hesitate to recommend DJ Morris to anyone.

"Bill and team were the first of several contractors to respond, the most detail-oriented and highly communicative, the most fairly priced (middle of the pack, not too high, not suspiciously cheap). Very easy to deal with. Showed up as promised, on-time, and did the job efficiently."

"David arrived within three hours after contacting him concerning a collapsed septic tank. He coordinated with town health department and completed job in timely manner, leaving the various areas he excavated in clean and tidy condition. The project was very difficult as he had to excavate right next to basement and foundations, and was a very confined space. David responded immediately to phone and text messages, and always kept me informed."

"At first it was suggested that the whole commode be replaced, but it was found out that the bowl was intact and that only the tank be replaced. This replacement was done and the new unit worked fine and nothing else was needed to be done. Great service, good workmanship and will recommend this company to others."

Septic Tanks FAQs, answered by experts

Common signs that your well pump is failing include fluctuating or consistently poor water pressure, sputtering water from faucets, or a complete loss of water. Other indicators are unusual noises coming from the pump, the pump running continuously, dirty or cloudy water, or a sudden, unexplained spike in your utility bills. While some issues, especially after a power outage, might be resolved by simply restarting the power or priming the pump, persistent problems suggest a more serious issue. If you notice any of these red flags, it is recommended to call a professional well pump service to inspect the system and determine whether it needs to be repaired or replaced.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

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.
