TL;DR
A sanitary well cap is a gasketed, vermin-proof cover that bolts onto the top of a well casing, sealing the annular space while a screened vent equalizes pressure. Unlike old slip-on caps, its compression gasket and sealed conduit entry keep insects, mice, and surface water from contaminating the aquifer, and most state well codes now require one on new wells.
What it means
A sanitary well cap is a gasketed, vermin-proof cover that bolts onto the top of a well casing, sealing the annular space while a screened vent equalizes pressure. Unlike old slip-on caps, its compression gasket and sealed conduit entry keep insects, mice, and surface water from contaminating the aquifer, and most state well codes now require one on new wells. A cracked or loose one is a frequent finding when a routine water sample comes back positive for coliform.
