Are you curious how much water your private well system can provide to your home? WIN Home Inspection Northwest Michigan can perform a well flow analysis (also known as 'well pump performance') to measure your well's flow (gallons per minute) and pressure (psi) over a short period of time. This information will let you know if your well system is delivering an adequate water supply to your home, if repairs or adjustments are warranted, 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, however, since those areas are not visible or accessible. Also, the well's recovery rate is not determined since this often requires nearly draining the well. For more information, please contact your local WIN inspector to see if this service is available in your area.

Check with your local authorities or real estate agent regarding any private well standards. Often maintenance of private well systems and ensuring the potability (whether the water is safe to drink) of well water is the responsibility of each private well's owner. Having the facts is important for all private well owners.
In general, 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.
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, WIN Home Inspection Northwest Michigan recommends obtaining the well's log from the property owner which should include important 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.), etc.
It is recommended to retest 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 may be more prone under certain seasonal and weather conditions. It is also recommended 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 shed 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.
