"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

"I had a new HVAC system installed by ( remove company name) which is now Heritage. I called Heritage about a service plan. They said a service needs to be done. I said your company just changed my filter and cleaned the system (literally a week ago). They said only the tech can sign you up so we need to do another service. I said I did not need another service. They insisted. I talked to Chris, one of the service managers and he would not budge. I called again and explained situation. Never heard back. Will not be doing business with a company that does not return phone calls when a customer is begging them to take money for a service plan. Such a poorly run company. So done with them. "

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

FAQs for sewer main clearing projects in Merrimack, NH

A plumber can clear a simple sewer pipe blockage in about an hour, but tougher clogs take several hours, and major problems can stretch into a full day. Remember that the city, not the homeowner, is responsible for the main municipal line. Your plumber will inspect the pipe, explain what’s happening, and give you a realistic timeline before the work begins.

Prevention comes down to smart use and routine care. Only flush water, approved liquids, and toilet paper—never wipes, floss, or cat litter. Toss food scraps and grease in the trash, and install strainers in drains to catch hair. Regular inspections can also help spot buildup early. Staying mindful of what goes down the drain is the easiest, least-expensive way to keep your line clear.

When hiring a sewer line company, don’t just focus on the price. Make sure the contractor is licensed, insured, and has good customer reviews. Ask for references to get a better sense of their work. It’s also a plus if they have years of experience or industry awards. Carefully review the contract and check that pricing is clear and transparent.

Sewer line cleaning keeps your entire plumbing system running smoothly. When the main line is clear, drains flow freely, toilets flush better, and unpleasant odors fade. Regular cleanings also ease strain on older pipes, helping prevent leaks and backups. Think of it as a plumbing tuneup that keeps everything connected and working efficiently while extending the life of your system.
