Things You Will Need
- Tape Measure
Most states don’t require a well cap, but a cap might improve your health. Sanitary wells are sealed airtight with a well cap; the cap prevents insects, rodents and surface water from entering the well.
A well cap might protect against other surface contaminants containing coliform bacteria, a bacteria that causes illnesses. Installing the cap provides long-term protection for your well casing.
- Measure the size of your current well cap or the diameter of your well casing; select a well cap. Most well caps are sealed on the well casing with bolts or screws around the side of the cap. Some well caps feature a small screen or vent in the top of the casing to allow for airflow. Caps are usually made of food grade plastic, concrete or fiberglass.
- Lay the well cap over the top of the well casing. The well cap must extend out of the soil to prevent water from entering the casing.
- Line up the well cap with the bolt holes on the well casing.
- Thread the bolts or screws through the holes to connect the well cap to the well casing. The bolts generally come with the well cap.
- Mold the soil around the well with your hands, so that any water or rain is redirected away from the well cap.
