Why Is My Boiler Running in the Summer? Understanding Indirect Hot Water in NH Homes

It is 80 degrees outside, your thermostat is not calling for heat, and then you hear the boiler fire up in the basement. For many New Hampshire homeowners, that seems strange.

PFAS Water Filter NH: What Well Owners Should Know

PFAS contamination has become a major water quality concern for many New Hampshire homeowners, especially families who rely on private wells.

Weak shower water pressure while multiple fixtures are running in a New Hampshire home

Why Your Water Pressure Drops When Everyone Is Home

Your shower is running normally. Then someone flushes a toilet. The washing machine starts filling. Someone turns on the kitchen faucet. Suddenly, that strong shower turns into a weak spray.

Thinking About a Heat Pump? Why Late Summer Is the Smart Time to Plan in New Hampshire

For many New Hampshire homeowners, heating is not just a comfort issue. It is a budget issue. A large number of homes across the state still rely on oil heat.

Hard Water in NH: What It Does to Your Plumbing, Water Heater, and Everyday Comfort

New Hampshire water can be tricky. In one town, the water may be naturally soft.

Why Your Water Heater Relief Valve Leaks in Summer

A small puddle near your water heater can be easy to ignore. Maybe it only happens once in a while. Maybe it dries up before you think much about it. However, if the water is coming from the temperature and pressure relief valve, often called the T&P valve, your water heater is trying to tell…

A slow drain is annoying. A main sewer backup is something else entirely.

However, during the warmer months, one of the most common causes…
