Enjoy a continuous source of water by allowing Mosman Well Works to work with you to guide you through their step-by-step guide to installing your Cornwall well water pump.

Mosman Well Works will provide you with the ideal water pump that fits your needs by determining which well water options will work best for you through a fixture analysis. Our supplies include:

  • Submersible pumps

  • Variable speed constant pressure systems
  • City water booster pumps
  • Irrigation pumps
  • Yard hydrants and hand pumps

Your Cornwall, CT home can be installed with two different types of pumps, a jet pump or a submersible (sump) pump.


The benefit of using a jet pump is the cost. This is the less expensive option of the two pumps. The downside it a jet pump will produce much more noise and will also generate a lower water pressure at about 50 psi. This pump operates by sucking the water through the pipes.


Often referred to as a sump pump, a submersible pump generates 30 percent more water pressure than a jet pump and uses less energy to work. This pump works by pushing the water from the ground up.
