"Andrew did a great job fixed my upstairs toilet, had other plumbers try to figure out why the toilet wouldn't drain, Andrew used a camera in the main drain and found the problem. Awesome job, we are all set with the toilet and he checked the whole house for any other issues. We will use Andrew in the future, we highly recommend his services."

"After a phone call with a representative that called me and discussion of the work I was looking for, and mentioning a number of times the work involved a site visit was scheduled. When the service person came to do an onsite evaluation, I was told: 'we don't do oil tank removals and installs.' Representative was obviously not trained for what I had requested during our phone conversation and that Nicholson Heating, Cooling, Plumbing and Electrical didn't do this service or wasn't informed of it during training."

"This story begins long before we bought our dream condo, when some fool decided that an ejector pump system would be the best way to deal with our below-grade kitchen. Our troubles began once we moved in -- 3 years ago-- and began cooking regularly, the way one does when trying to eat well and not go out all the time. The pump backed up constantly, flooding the hallway and leading to amazing fungus sprouting from the wall. We called many different plumbers, most who refused to help, given the strangeness of our set-up (these pumps are almost never used in a kitchen, but typically for bathrooms or septic systems). We had some plumbers come out who I will politely avoid naming, who charged us for work that didn't do any good... eventually we got to the point where we could not use the kitchen sink or dishwasher without first checking the pump, as at any time it might unpredictably overflow. This went on and on, but then Provost came to our rescue! Although it took us a few tries to coordinate a time, we finally met Russ, who sweated through FIVE HOURS of intense labor, discovering and repairing the poor workmanship of at least 2 previous plumbers, successfully re-installing an alarm system, and providing us with an enyzme cleaning system to use as well. He insisted on closing the cabinet on the whole thing, which we did with trepidation, as we had gotten used to not trusting the pump. "You really shouldn't have to touch it again," he told us. "But call me if you have any problems!" It has been 3 weeks and we have yet to call, which feels about as close to a home-ownership miracle as we can get. I will sing the praises of these guys across Boston."

"Very knowledgeable and friendly. Most importantly, I didnâ t feel as though I was being pressured into repairs or services I didnâ t need. If your looking for an honest company I recommend having S&G look at any septic problems orTitle V you may need."

Septic Tanks FAQs, answered by experts

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.
