Joseph Watts founded our company in 1874 on the belief that water boilers in textile mills shouldn’t explode. What started with a pressure relief valve in a tiny New England machine shop, has paved the way for today’s high-quality, worldwide water solution technologies. From melting ice on entire city blocks from the ground up, to filtering safe drinking water in isolated, weather disaster zones, you need water and water needs Watts.

We are a global leader of quality water solutions for residential, industrial, municipal and even many commercial settings.
