• Casing is put in the well to stop the hole from collapsing and to prevent the risk of surface water getting into the well.
• A seal of "grout" is often placed between the casing and the drilled hole to stop any surface water moving down outside the casing.
• The most common well pumps in use are called "submersible". They are powered by electricity and push the water up to the surface.
• In any area where there is frost, the water pipe comes from the well through a pitless adapter below ground level. In warmer climates there is no need to use a pitless adapter; the water pipe can come out of the top of the well.
• Water should drain away from the well head and the well cap should be tightly sealed.
