Water Flow Testing in CT and RI
Do you want to know how much water your private well system can provide to your home? Anchor Home Inspection can perform a well flow analysis (also known as ‘well pump performance’) to gauge your well’s flow (gallons per minute) and pressure (psi) over a short period of time. This information will tell you know if your well system is delivering enough water supply to your home, if repairs are needed, adjustments needed, or if you may need to find another water source for your home. This well flow analysis won’t determine the depth or capacity of the well casing, pump, or aquifer since those areas are not visible or accessible. Also, the well’s recovery rate is not gauged because it requires draining the well.
Check with your local municipality or real estate agent regarding any private well standards. Having the facts is important for all private well owners since it will be up to you to maintain the well.
Overall, a well pump should be able to deliver at least 4 gpm (gallons per minute) and at least 40 psi (pounds per square inch) pressure to a residential home. The well pump test is performed with no other water running in the home in order to obtain accurate measurements. For comparison, most public water utilities supply between 40 and 75 psi to the home.
General Well System Information
It is recommended that all well systems be serviced regularly by a licensed plumber or a qualified well contractor. For all property transactions where there is a well, Anchor Home Inspection suggests obtaining the well’s service log from the property owner which generally will include detailed information such as: locations of the well’s components, pump and casing depth, service records, well yield data, age of the well’s components (pump, tank, wiring, etc.), and more.
It is recommended to test your home’s well water every 14 months for safety reasons. This allows for testing to span the seasons after a few years; different contaminants are more likely to happen under certain seasonal and weather conditions. It is also suggested that no pesticides or fertilizers be applied to the ground within 100′ of the well casing as this can cause well contamination. Pets should be kept away from well casings and the ground around the well casing should also guide water away from the well casing. The top of the well casing should stick up above grade (at least 8″ is suggested, 12″ is better) to help prevent contamination of the well water.
