More about the Boshart Certified Well Cap

Simple Pump's 6-inch certified Boshart well cap.(For a pitless installation in a 5″, 6″ or 6.25″ well.)

The Boshart well cap is a “certified” design…. screened, bug-proof, water-tight, vented with a compressive casing seal.

The Boshart allows the professional to install a well cap that meets code in many states and provinces.

The Boshart well cap is a clamshell design. The top of the cap has only one opening — for the Simple Pump.

The wiring from your submersible exits via the bump-out you can see on the left-hand side of the cap picture.
