Water Heater Repair in Pembroke, MA
Pembroke's water carries naturally occurring iron and manganese, and brown water is a known problem the town expects to take years to fix. That sediment can end up in your water heater. If yours has quit or is leaking, call and get a plumber out.
What shapes water heater trouble in Pembroke
highest iron level in town water in 2025, against a 300 ppb aesthetic standard
Source: Town of PembrokeWhy Pembroke's water turns brown
Pembroke runs four active wells with three treatment facilities and about 135 miles of water main. The Hobomock and Bryantville wells need treatment to remove high levels of iron and manganese, and all the wells get potassium hydroxide to raise the pH and cut corrosion. Even so, in 2025 iron tested as high as 753 ppb and manganese as high as 197 ppb, both above their aesthetic limits. The town says discoloration during flushing comes mainly from iron deposits inside its ductile iron mains, and that the water is safe to use, though it can stain laundry.
Residents told NBC10 Boston in January 2025 that brown water shows up far more often than the twice-yearly flushing. The water superintendent called it an aesthetic concern, not a health concern, and said fixing the sources will take years and a lot of money. The department presented a $75 million improvement plan in December 2024, and the town has added an online form for reporting discolored water.
Keeping that sediment out of the tank
Iron and manganese that get into the house settle at the bottom of a water heater. Over time that layer can cause rumbling, discolored hot water and less hot water than you're used to. In a town with frequent brown water, flushing the tank once or twice a year is worth doing. If only the hot side runs rusty while the cold is clear, the tank itself may be rusting, and that's worth a look.
The town's flushing page warns that flushing causes discolored water in varying degrees in every section of town. Its advice: check before doing laundry, then open the outside faucet closest to the water meter and run it for several minutes. If it still isn't clear, wait about an hour and try again. If you have a water softener, put it into regeneration once flushing in your area is done. Clearing the lines with cold water first keeps the stirred-up iron out of your water heater.
Oil, gas and private wells
About 52% of Pembroke homes heat with gas, 32% with oil and 5% with propane. In an oil-heated home, hot water often comes from the boiler through a coil or an indirect tank, so tell the plumber what you have. Gas comes from Eversource. About 90% of homes are owner-occupied, and the median home was built in 1974.
Not every home is on town water. Pembroke's Board of Health regulates private wells, and a well can send its own iron and sediment into a heater. For a water problem after town hours, the water department says to call the police non-emergency line, 781-293-6363. State rules require a permit before plumbing or gas work is installed, replaced or repaired, and the licensed plumber or gas fitter pulls it.
Safe steps for Pembroke homes
- Leaking? Close the cold water valve on top of the tank.
- Turn off the gas valve or the breaker for the heater.
- Gas smell? Eversource serves Pembroke. Leave the house, call 911 from outside, then report it to Eversource's gas emergency line.
