Well Pump Service - Installation & Repairs

Mosman Well Works works to provide New Haven County homeowners with exceptional well water services at affordable prices. The well pump service process normally begins with the installation of a well water pump.


Mosman Well Works will guide you through every step of the installation process to make sure you always have a source of running water. We provide the proper pump to fit each client’s unique needs.

Through a fixture analysis, we will identify which options are best suited to your water situation. We offer a variety of supplies, including:

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

You can choose between a jet pump or submersible (sump) pump for your New Haven County home. We will work with you to decide which option is best for you.


Jet Pumps generally produce more noise while generating lower pressure (typically around 50 psi). This is because the pump sucks up water through the pipes, rather than pushing the water through. Though not as preferred, jet pumps can be a more affordable option.


Submersible pumps, also known as sump pumps, are more popular than jet pumps. Water is pushed up from the ground with sump pumps, requiring less energy and resulting in up to 30% higher pressure.


Mosman Well Works has years of experiencing servicing pumps throughout New Haven County and the rest of CT. Our professionals are experts at well pump service. Our expert specialists are always available to help if there are any issues in your water system. We are able to visit your New Haven home and inspect any existing system for a free, no-obligation estimate.

We understand your needs at Mosman Well Works, and we can guarantee a limited disruption to your water supply.

Diaphragm & Static Storage Tanks

Water pressure can drop rapidly if you have broken pipes, malfunctioning pressure, or if your faucet aerator or sediment filter is clogged. Our team can swiftly identify the problem and provide a solution, no matter the cause.


Diaphragm tanks allow a water system’s water and air to be separated to effectively prevent water logging.In order to lessen the amount of time your pump is required to run, the diaphragm tank adjusts itself when there is a sudden change in pressure.


Static storage tanks are especially useful when facing water production issues.

Our expert team can provide cost-effective solutions after identifying problems with any tank. It is important that your New Haven County home has running water, so offer emergency water tank repairs and replacement around the clock.
