Trusted Plumbing Repair Services in Massachusetts

Licensed Plumbing Repair, Installation, and Replacement for Plymouth County

When a faucet drips, a drain clogs, or a pipe bursts behind a wall, you need a plumber who shows up on time, treats your home with respect, and fixes the problem the first time. At 3R Plumbing & Mechanical, we provide licensed plumbing repair across Massachusetts for homes of every age and size, from coastal cottages in Cohasset to multi-bath colonials in Hingham. Our technicians arrive in fully stocked trucks, diagnose the issue quickly, and walk you through your options before any work begins. We have served South Shore homeowners since 1975. Whether you have a simple leak, a stubborn drain, or a complex repipe project, we deliver clean, code compliant repairs and clear pricing every time.

Common Plumbing Problems We Fix

Plumbing problems rarely show up at convenient times. Our plumbers carry the most common parts on the truck so we can usually finish the repair on the first visit.

  • Dripping or leaking faucets
  • Running or weak flushing toilets
  • Slow or clogged drains
  • Burst or frozen pipes
  • Hidden pipe and slab leaks
  • Garbage disposal failures
  • Sump pump problems
  • Low water pressure

Drain Cleaning and Sewer Service

A slow or backed up drain rarely fixes itself. We offer professional drain cleaning for kitchen sinks, bathroom sinks, tubs, showers, toilets, floor drains, and main sewer lines across the South Shore. Our trucks carry mechanical augers, hydro jetting equipment, and sewer cameras so we can clear stubborn clogs and verify the line is clean before we leave. Every drain service includes:

  • Camera inspection of main sewer lines
  • Mechanical cabling and snaking
  • Hydro jet cleaning for grease and roots
  • Septic and city sewer compatibility checks
  • Cleanout installation when needed

Repair vs. Replacement When to Consider New Plumbing

If your home was built before 1990 and still has the original supply lines, drains, or fixtures, you may be living with hidden risk. Pinhole leaks, polybutylene pipe failures, corroded galvanized lines, and aging cast iron drains are common throughout Plymouth County and the South Shore. In some cases a targeted repair still makes sense. In other cases a partial repipe or fixture replacement is the smarter long term decision. We look at the full picture, including pipe material, age, water quality, repair history, and visible signs of corrosion. When repair costs start to climb, when leaks repeat in the same area, or when your insurance carrier flags polybutylene or galvanized supply lines, replacement becomes the more reliable move. We install fixtures and supply lines from trusted manufacturers like Moen, Kohler, Delta, Toto, and Uponor, and we offer clear Good, Better, Best options so you can choose what works for your home and budget. Every job is guaranteed in writing.
