What Westwood's water test means for your water heater

The Dedham-Westwood Water District's 2025 report lists hardness from 74.1 to 134 ppm as calcium carbonate. That is 4.3 to 7.8 grains per gallon, with an average of 104 ppm (6.0 grains), which counts as moderately hard. Calcium and magnesium drop out of solution when water is heated, so a tank collects them as a layer on the bottom.

That layer is the practical problem. A gas tank heats from underneath, so sediment sits between the burner and the water, and you hear popping as steam escapes through it. An electric tank can bury its lower element in scale. A yearly drain-and-flush slows the buildup, and an anode rod check shows how much protection the tank has left.

The limits matter. Hardness varies with the part of the district you live in and with the sampling date, so your tap may land above or below that average. A test strip or a lab test on your own water beats assuming 6.0 grains.

Hard-water signs and what they usually mean

A sign alone does not prove the cause, so the plumber confirms it on site before anything is replaced.

Tankless service: the descaling schedule hard water sets

A tankless unit heats water as it passes through a narrow heat exchanger, so even a thin scale coat cuts flow and raises the temperature the burner must reach. At an average of 6.0 grains, scale is a question of when, not if. Follow the maker's service interval and shorten it if your own test reads high.

Descaling means isolating the unit with service valves, circulating a descaling solution through it with a small pump, then flushing and cleaning the inlet screen. If your unit has no service valves, the visit begins by installing them, which is worth doing once. That is the core of our tankless water heater service.

Error codes are a clue, not a verdict. A flow or temperature code on a scaled unit often clears after descaling. A code that returns right after points to a sensor, a vent or a gas supply issue.

Repair the water heater or replace it?

Hard water pushes some tanks toward the end of their life early. The age on the data plate and the location of the leak decide most of it.

Replacement and repair: what each visit involves

Water heater replacement is the usual answer when the tank itself leaks. The visit covers draining, disconnecting, setting the new unit, venting, a pressure relief valve with a drain line, and an expansion tank where the setup calls for one. State rule 248 CMR 3.05 requires a permit before work starts, with an emergency exception that still requires the inspector to be notified, so ask the Canton Building Department about your specific job.

Water heater repair covers the cases where the tank is intact: thermostat, elements, igniter, thermocouple, relief valve. If there is a gas smell, leave the house and call the gas utility or 911 before you call a plumber.

Homes with several bathrooms: supply, recovery and pipe runs

If your home has several bathrooms, one heater carries more demand than it does in a small house. Two showers and a dishwasher at once can empty a tank sized for fewer fixtures. A tank with a slow recovery leaves the last shower cold, and a tankless unit may need a higher flow rating or a second unit.

Long pipe runs add a second problem. Water cools in the line between a distant bathroom and the heater, so you wait and waste water. A recirculation loop or a small point-of-use heater solves that, and a plumber should look at your layout before quoting either option.

PFAS treatment construction: context, not a plumbing problem

The district reported a PFAS6 highest quarterly average of 16.4 ppt against the state limit of 20. Ion exchange treatment at the White Lodge plant in Westwood began construction in October 2025, with completion estimated for spring 2027. That is a utility project, and it does not mean your pipes need work.

If you want a filter on a drinking tap, ask the district what it advises. A point-of-use filter sits on one tap and is separate from the heater and the main plumbing. We can fit the connection, but we cannot certify what a cartridge removes.

Leak detection when the heater is not the source

Water on the floor near a heater is not always the heater. A leak detection visit uses a moisture meter, acoustic listening and pressure testing to separate a tank leak from a dripping supply line, a condensation line or a pipe in the wall above. Check your water meter with every fixture off, and if the dial keeps moving, tell dispatch.

Sudden burst-pipe damage is often covered by homeowners insurance, while a slow leak over months is commonly excluded. Your policy wording decides.

Reaching your Westwood address

Westwood stretches from Route 128 Station and University Station in the far eastern corner toward Islington, with Route 109 and Hale Reservation as landmarks in between. None of that changes the plumbing, but it helps when you call. Give the dispatcher your street, the nearest cross street or landmark and which entrance to use.

Nearby towns and related services

Westwood shares a river boundary with Norwood, so homeowners comparing nearby service can read about plumbing help in Norwood and about emergency plumbing in Stoughton, both served from the same Canton dispatch.
