Well Pump Service - Installation & Repairs

Mosman Well Works works to provide Harwinton 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 is there through every step of the installation process to ensure you always have a source of running water. We want each customer to have the setup that best fits their needs.

Through a fixture analysis, we can find the best solution to your well situation. Some of our supplies include:

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

You have the choice between a jet pump or submersible (sump) pump for your Harwinton, CT, residence. We’ll explain each option in order to help you decide which choice best fits your circumstances.


Jet Pumps are noisier and generate lower pressure (typically around 50 psi). The pump operates by sucking the water up into the pipes as opposed to pushing the water though. Although jet pumps cost less, they are generally the less preferred option.


Submersible pumps, also known as sump pumps, are often favored over jet pumps. In a submersible well water pump, water is pushed from the ground upward using a sump pump. This produces up to 30% higher pressure while requiring less energy.

Our professionals are experts at well pump service. We will come to your Harwinton home, inspect your existing system, and provide you with free, no-obligation estimate.

Diaphragm & Static Storage Tanks

A clogged sediment filter or faucet aerator, broken pipes, or malfunctioning pressure can cause water pressure to quickly drop. Regardless of the cause, our team will can assess the situation and propose a solution.


Diaphragm tanks allow the well system’s air to be separated from the water, which effectively prevents water logging. The diaphragm tank adjusts to sudden changes in pressure. This is extremely useful in decreasing the amount of time your pump needs to run, saving both wear and tear and energy.


Static storage tanks are particularly useful when facing issues with water production. 

Our expert team can help identify problems with your tank and discuss solutions that fit your budget. It is critical that your Harwinton home has running water. Mosman Well Water works around the clock to offer emergency water tank repairs and replacements.
