F.R. Mahony & Associates is a Rockland, Massachusetts company homeowners call when a grinder or ejector sewage pump fails — the exact problem behind nearly every review on file. The company has serviced these systems since at least the mid-2010s, when it handled warranty and service work for E/One-brand pumps under municipal contracts in towns like Marion, and it was acquired by Cummins-Wagner Co., a water and wastewater equipment distributor, in 2020. Its Google reviews run 2022 through 2026, all five stars, and the pattern is speed paired with a technician who explains the fix rather than just doing it and leaving. In an April 2026 review, a homeowner whose grinder-pump alarm never sounded got the problem diagnosed after a referral from their own plumber. In a 2025 review, a customer called late on a Saturday and had technician AJ on-site by Sunday morning with the pump removed and repaired; in another 2025 review, the same AJ walked a customer through every part of the pump during a separate repair. Other reviewers name Nick, Kyle, Lucas and John for similar on-site explanations, including a 2024 review describing staff Brenda and Samantha handling an emergency call for a homeowner in Billerica. Pricing comes up favorably more than once. In a 2023 review, a homeowner said another company quoted $8,500 in labor plus $4,000 for a new pump, and F.R. Mahony did the same repair for $3,851; a separate 2023 account describes being told the service-call fee and hourly rate upfront before any work began. Before calling, know this is a narrow specialty: F.R. Mahony works on grinder and ejector pump systems specifically, not general plumbing, and it operates as much as a distributor of E/One pump equipment as a service company. That's the right call for a failing grinder or ejector pump; for broader plumbing work, it's worth asking whether that's something they take on.

We purchased a home 11 years ago that had a Grinder Pump for the sewer system connection to the street. A few years in, in 2019, I noticed that the pump was running very often. We didn't hear an alarm from the box in the basement. Our plumber referred us to F. R. Mahoney. We called them and they came out the next day. We did need to replace the pump (who knows when it was installed or serviced) and during the replacement they made sure that the alarm system was working. The other day, I heard a loud buzzing from the basement, which was coming from the alarm. We followed the reset instructions, and the system continued to work, but called to discuss the issue. Since it had been 7 years, and we had never had it serviced, we wanted a service anyway. Tim came out a few days later, and discovered a few damaged parts, which he replaced (instead of telling us we needed a new pump), thoroughly cleaned the whole unit, and then tested the system. As others have said, he explained what he was doing, what had caused the problem, and did it with a smile!. Can't say enough about this company's pleasant and efficient response. We have learned that a service call every 2-3 years should prevent a big failure. Recommend them without reservation.
We had an issue with our grinder pump today (9/14) and were so thankful to have AJ come out. He not only fixed the problem but also took the time to teach me and show me all the parts of the pump. As someone with an electrical background, I really appreciated the level of detail and pride he put into his work. On top of that, AJ was an absolute pleasure to have around—such a nice guy who truly represents his company well. Even my kids thought he was great! Thank you, AJ! – Steve, Cohasset”
Best experience ever, called late on Saturday, AJ was there first thing on Sunday morning, removed grinder pump and found and repaired problem. Had house running again in no time. Couldn’t ask for better service.
