What a plumber in Boston actually does

A licensed plumber handles anything that touches the pressurized water supply, the DWV (drain-waste-vent) system, the gas line, or fixed gas-fired appliances like water heaters and pool heaters. A typical service call begins with a 15–30 minute diagnosis: the plumber will run faucets, check water pressure at a hose bib (40–80 PSI is normal), inspect supply lines and shut-off valves, and — if the call involves a drain — usually run a snake or scope a camera before quoting the repair. Bigger jobs (re-pipes, sewer-line work, water-heater swaps) require a written scope, a permit pulled in the homeowner's name, and at least one rough/final inspection by the local building department.

Questions to ask before you hire in MA

Are you licensed in this state, and what is your license number?
Do you carry general liability and workers' comp? (Get the policy number, not just a "yes.")
Is the price flat-rate or hourly, and what does it include — diagnosis, parts, disposal, permit?
If the job grows in scope, how is the change order priced and approved?
What is the warranty on labor and on the manufacturer parts?
Will you pull the permit, or do you expect me to?

A plumber who quotes a major job sight-unseen, refuses to put the price in writing, or asks for more than 30% up front. Door-to-door "I noticed something wrong with your house" pitches after a storm are almost always scams.

Seasonal plumbing checklist for Boston homeowners

Spring

Run every faucet, shower, and outdoor spigot for 60 seconds; watch for slow drains, drips at the base, and drops in pressure.
Inspect the water heater anode rod if your unit is over 5 years old; replace if more than 50% consumed.
Test the sump pump by pouring a 5-gallon bucket of water into the pit; the pump should activate and the pit should empty within 30 seconds.
Re-aim sprinklers and clear hose-bib vacuum breakers before the irrigation season.
Snake or enzyme-treat slow drains before summer guest season.

Fall

Disconnect garden hoses and shut off exterior hose-bib valves before the first hard freeze.
Insulate any exposed pipes in crawlspaces, garages, or unheated basements with foam sleeves.
Drain and winterize irrigation lines (most municipalities and HOAs require this by mid-November).
Flush the water heater tank to clear sediment that reduces efficiency.
Test main water shut-off valve so you can find it fast in an emergency.

Winter

Open cabinet doors under sinks on outside walls during cold snaps to let warm air reach pipes.
Let faucets on outside walls drip overnight when temperatures drop below 20°F.
Maintain at least 55°F indoors even when the home is unoccupied.
