Plumber in New Hampshire

If you need a plumber in New Hampshire, the granite under the house sets the agenda. Private wells serve a large share of homes, arsenic and radon occur naturally in the bedrock, PFAS has shown up around the seacoast and southern towns, and winters freeze pipe. This page explains those causes and the first steps to take.

Why Plumbing Problems in New Hampshire Are Different

Private Wells Everywhere

Many New Hampshire homes use private wells, and the state’s private well guide says well owners are responsible for testing. A basic test should be done regularly, and any change in taste, odor or color deserves a quick check.

Arsenic in Bedrock Wells

Arsenic occurs naturally in some granite and other bedrock, and the state’s limit has been five parts per billion since 2021, half the federal level. Home test strips cannot detect it at that level, so use a certified lab.

Radon in Well Water

Radon forms from uranium in granite and can dissolve into well water and then escape into indoor air while you shower or run taps. Test water and air, and ask a plumber and a radon professional about treatment.

PFAS in the Seacoast and South

PFAS contamination is concentrated in southern New Hampshire and the seacoast, linked to industrial sites and former military installations. The state runs a rebate program for private wells that exceed limits, so check current rules.

Cold Winters and Frozen Pipes

Winters bring deep frost and long freezes that split pipe in exterior walls, porches and camps. Insulate exposed lines, drain outdoor spigots and winterize seasonal homes before the first hard freeze.

What to Check Before You Call a New Hampshire Plumber

Confirm whether you use a public system or a well, find the main shutoff and note the age of the pump and pressure tank. Keep recent test results ready, since arsenic, radon or PFAS findings decide which treatment equipment makes sense.

Safety First: When a New Hampshire Plumbing Problem Is an Emergency

If you smell gas, leave the home and call 911 or the gas utility from outside. For a frozen pipe, shut off the main valve, open the faucet and thaw slowly, never with an open flame.

Frequently Asked Questions — New Hampshire Plumbing

Is New Hampshire tap water safe to drink?

Public systems report meeting standards, but private wells are the owner’s responsibility. Arsenic, radon and PFAS can occur, so test your well through a certified lab and read your utility report if you are on a public system.

Does arsenic occur in New Hampshire well water?

Yes. It occurs naturally in some bedrock, and the state limit is five parts per billion, half the federal level. Many wells are fine, but only a lab test can tell you, and treatment options exist if your result is high.

Who should I call for a plumbing emergency in New Hampshire?

Close the main valve first, then call a plumber near you. If you have a well, also switch off the pump at the breaker and tell the plumber about the pressure tank. For a leak in the street call your water utility, and for gas odors go outside and call 911 or the gas company.

How do I find a good plumber for a New Hampshire well system?

Choose one who inspects the pump, pressure tank and treatment equipment before quoting, explains the repair in plain terms and puts findings in writing. Share recent water test results so they can match equipment to the water.

How often should I test my New Hampshire well?

Test for bacteria and nitrate every year and for arsenic, radon and other natural contaminants at least every few years, or after any change in taste, odor or color. Use a certified lab, because home strips cannot detect many of these problems.

What is the PFAS rebate program in New Hampshire?

The state offers a rebate program for private wells where testing shows PFAS above state limits, helping pay for treatment equipment. Rules and amounts change from time to time, so check the state environmental agency’s current page before you buy a filter or treatment system.

How do I keep New Hampshire pipes from freezing?

Insulate pipes in exterior walls, porches and garages, then disconnect hoses and drain outdoor spigots before the first hard freeze. Open cabinet doors under sinks on cold nights, let a faucet drip, and winterize camps and seasonal homes before leaving.
