Fluid Filler was developed to alleviate aching knees every time a pool owner kneeled on the cement to retrieve water from their pool for testing.

Pool chemical testing kit manufacturers recommend that the pool water used for testing is acquired 18 inches below the surface. Water above this will have diminished chlorine levels due to sun light (UV) exposure.

The Fluid Filler design is extremely uncomplicated to save on cost and be rebuild-able. It only has two moving parts and is made in America!

Manufactured with heavy gauge steel, then zinc plated, this tool will hold up to the test of time and provide years of service when properly used and maintained.
