4" Locking Well Caps 

• Well caps are easy to install with a rubber mallet.

       It only takes 1 minute per well... just whack it with

       a rubber mallet and the internal ribs on the well

       cap will bite into the PVC well casing making it

       almost impossible to remove.

• Locking well cap will minimize theft.

• Once the well pump holder and well pump cap is installed, future sampling/purge events will take so much less time per well to sample.
