New Hampshire combines harsh winters with a high reliance on private wells — a large share of residents get their water from wells rather than public systems. Pump, pressure tank and water treatment issues are everyday plumbing work, alongside frozen pipe repairs.
Older homes and farmhouses across the state often have aging supply lines and drains, and many basements need sump pumps during spring snowmelt.

Well systems
Low pressure, sputtering faucets or a pump that runs constantly often point to the pressure switch, pressure tank or pump itself.
Water quality
Bedrock wells can contain naturally occurring arsenic, radon or high mineral content, so testing guides treatment choices.
Winter freeze-ups
Unheated crawl spaces, garages and additions are the most common places for pipes to freeze.

New Hampshire plumbing questions
Why does my New Hampshire well pump keep turning on and off?
Rapid cycling is often caused by a waterlogged pressure tank or a faulty pressure switch. Left unrepaired, it can burn out the pump.
How often should I test my well water in New Hampshire?
State guidance recommends regular testing — commonly every few years for a standard panel — and after any change in taste, color or odor.
Are private wells common in New Hampshire?
Yes; a large share of New Hampshire residents use private wells. Testing for arsenic, radon and other contaminants is recommended because they occur naturally in the state’s bedrock.
How deep should water lines be in New Hampshire?
Water lines need to be below the frost line, which is deep in northern New England. Shallow lines and exposed sections freeze.
Why does my well pump cycle on and off constantly?
A waterlogged pressure tank, failed pressure switch or leak are common causes. Constant cycling wears out pumps.
Do New Hampshire homes need septic inspections?
Septic systems should be pumped and inspected periodically. Some towns and lenders require inspections at sale.
How do I protect pipes if the power goes out in winter?
If heat will be off for a long time in freezing weather, shut off the water and drain lines, or use backup heat.
Is hard water a problem in New Hampshire?
Some wells have hard water or high iron and manganese, which stain fixtures; testing determines the right treatment.
