Plumbing Services in New Hampshire

Wells, pressure tanks and the water you actually drink

Many New Hampshire households draw water from a private well instead of a municipal line, which means the plumbing starts at the well pump, not the meter. A typical system has a submersible pump, a pressure switch, a pressure tank and a filter or treatment device. When water sputters or pressure swings, the fault may be outside the house.

Common well-side symptoms

• Faucets that sputter or surge.
• A pump that turns on and off rapidly, called short-cycling.
• Low pressure that is worse at certain times of day.
• Sediment, cloudy water or staining at fixtures.

Where a plumber stops

Never open a pressurized tank or work on the well's wiring yourself. See sump and well pump repair for how pumps are diagnosed, and say on the call whether you have city water or a well.

Emergency plumber New Hampshire homeowners look for in winter

An emergency plumber New Hampshire search is usually triggered by frozen or burst pipes, a dead pump with no water, a failed boiler or a sewage backup. Guidance on emergency plumbing explains what is urgent. Terms like "24 hour plumber" are common searches, but availability is confirmed by phone.

While you wait:

1. Shut the main valve if pipes are leaking.
2. Turn off the water heater power or fuel.
3. Keep away from electrical equipment near water.
4. Take photos for insurance.
5. Gas or propane smell means leaving and calling the gas supplier or 911 from outside.

Deep frost, camps and second homes

New Hampshire frost can reach far below the surface, so buried lines are set deep and exposed lines need insulation. The most vulnerable spots are pipes in exterior walls, garages, unheated additions and camps closed for the season. A seasonal home left without heat can burst multiple lines before anyone notices.

Shutting down a camp

• Shut off and drain the main supply.
• Open all faucets and drain low points.
• Ask a plumber about traps, toilets and the water heater.
• Consider a remote temperature monitor for any heated space.

After a freeze

Water often only appears once ice melts, so have the main valve located before thawing. See burst pipe repair for what the repair involves.

Salt air and older colonials

Coastal salt air can be hard on outdoor fittings and exposed metal, and older colonial homes near the water mix generations of piping. - Corroded exterior fittings, hose bibs and unions near the water.

• Mixed-generation piping in colonials that were added onto.
• Basements with sump pumps near high groundwater.

Rental housing tied to student and seasonal cycles makes fast, clear communication helpful.

Dover, Rochester and the Strafford County corridor

Dover has ZIP 03820 (about 4.3 miles from University of New Hampshire), ZIP 03821 (about 5.2 miles from University of New Hampshire) and ZIP 03822 (about 5.2 miles from University of New Hampshire). Rochester includes ZIP 03839 (about 9 miles from University of New Hampshire), ZIP 03866 (about 12 miles from University of New Hampshire), ZIP 03867 (about 12 miles from University of New Hampshire) and ZIP 03868 (about 3 miles from Skyhaven Airport). Barrington is ZIP 03825 (about 7 miles from University of New Hampshire).

Rentals, farmhouses and ledge

Older farmhouses in this corridor are often built on or near granite ledge, which limits where lines and drains can run. Additions may have been plumbed by different people in different decades.

• Ask whether the sewer is municipal or septic.
• Ask where the main shutoff is, and whether it still closes.
• Tenants should report drips early, since a slow leak in a ledge-set foundation can go unnoticed.

Water quality and how it hits your pipes

Water in parts of New Hampshire can be acidic and soft, and well water may carry iron, manganese or other minerals. Acidic water can slowly attack copper, leaving pinhole leaks, and mineral content can stain fixtures and coat heater elements. A plumber can test pressure and flow, inspect pipes and coordinate with a water-treatment provider when the problem is water chemistry.

Signs your water is affecting the plumbing

• Blue-green staining at fixtures hints at copper corrosion.
• Orange or brown staining points to iron.
• A rotten-egg smell often relates to the water heater or well.
• Faucet aerators that clog often signal sediment.

Radon is a concern sometimes raised for well water in granite regions, and testing and treatment are handled by specialists, so mention it rather than guess.

Water heaters and boilers

Many homes use oil, propane or electric water heaters, and some use indirect tanks fed by a boiler. A water heater repair near me call is often about lukewarm water, a leaking tank or a tripped burner. See water heater replacement for repair-versus-replace decisions.

Fuel choices

Propane tankless water heaters suit properties without natural gas, and electric tankless units depend on panel capacity. A tankless water heater installation must also be sized for cold incoming water.

When to ask about replacement

Ask about water heater replacement near me timing when a tank is leaking, rusting or repeatedly failing.

Septic systems and sewer lines

How septic behaves

Outside the towns with municipal sewer, a septic tank and drain field handle wastewater. Slow drains in every fixture, gurgling and wet spots in the yard can point to a full tank or a failing field. In sewered areas, sewer line repair may involve roots and older pipe; a sewer camera inspection shows what is happening, described under sewer camera inspection.

Septic dos and don'ts

• Do not pour chemical cleaners into a septic system.
• Do not drive over the drain field.
• Ask for an inspection before you buy a house with septic.
• Keep grease, wipes and paper towels out of the drains.
• Know where the tank lid and cleanout are.

Drains and hydro jetting

Drain cleaning near me covers kitchen grease, hair, laundry lint and roots. Hydro jetting cleans pipe walls; read hydro jetting. For municipal laterals, sewer line replacement and trenchless pipe repair are options, though frozen ground can affect digging.

Leaks, slabs and hidden water

Finding a hidden leak

Leak detection services locate hidden water without opening everything; see leak detection. Slab leak repair is less common in basement and crawl-space houses but occurs in additions and slab-on-grade rooms. Look at slab leak repair.

Toilets, faucets and disposals

Everyday repairs

Toilet repair covers running tanks and weak flushes, and toilet not flushing helps you decide when to stop. Garbage disposal repair typically means clearing a jam or replacing a seal. See garbage disposal repair for the basics.

• A running toilet usually needs a flapper or fill valve.
• A dripping faucet is often a worn cartridge or washer.
• A humming disposal is jammed; do not put a hand inside.

Bathroom updates in older New England homes often reveal old supply lines, so a plan for bathroom remodel plumbing should allow for surprises behind the wall.

Gas, propane and safety

Never a do-it-yourself job

Homes may use natural gas, propane or oil. Gas leak detection is never a DIY job: leave, avoid switches and flames, and call the gas supplier or 911 from outside. New appliances fall under gas line installation.

Boilers, radiant heat and the plumbing that touches them

Hot-water baseboard and radiant heat systems share fittings, expansion tanks and makeup valves with the domestic plumbing. When a room stays cold, or a boiler loses pressure, a leak in the heating loop may be involved. A plumber can check the makeup valve, look for weeping fittings and tell you when a heating specialist is the better call. Older systems may also have air in the lines, which shows up as gurgling or uneven heat, and bleeding a system is a routine task best done by someone who knows the manufacturer's steps.

Old houses, new problems

Many New Hampshire houses are older than the codes that now govern them, so a repair can uncover surprises: lead-tin solder joints, cast iron stacks, buried oil tanks left from past heating systems or a shutoff that has not moved in decades. None of this is unusual, and it is why a plumber may want to look before quoting. Photos of the area, the age of the house and a description of past repairs make that first conversation much more accurate and useful.

Cost factors

Quotes depend on access, depth, materials, permits, fuel type and time of day, and figures are confirmed by phone; see plumber cost. Have your town, ZIP code, water source and symptoms ready.

• Well pumps and treatment equipment are quoted differently from house plumbing.
• Winter access to buried lines can add time.
• Older piping may need extra repairs found once walls are open.
