Frequently Asked Questions
The cap covering a well may be a small part of the overall household water well system, but it is an extremely important one.
A properly installed well cap separates potential pollutants from your drinking water. The cap, which should be sealed tightly at all times, keeps out everything from liquid contaminants to bugs that can crawl inside a well and wreak havoc.
Routine maintenance and inspection of water wells and well pump systems can help protect water quality, ensure your well is operating properly, prolong the useful life of the well system, and protect your investment. The greatest of all these is the protection of your health, as water quality issues can have adverse health impacts without any detectable indicators.
The primary components of water well systems include casing, well caps, well screens, and pitless adapters.
Casing is the tubular structure that is placed in the drilled well to maintain the well opening. Along with grout, the casing keeps possibly contaminated surficial water from reaching the aquifer zone underground and prevents contaminants from mixing with the water. The casing also holds back unstable earth materials so that they do not collapse into the well. Some states or local governing agencies have laws that require minimum lengths for casing.
