Eliminate the cross threaded and broken off screw studs that exist with our Cam-loks to make the water tight seal again without breaking concrete.
When the 36", 39" or 42" retrofit is installed and the Cam-loks are tightened in a rotational alternating manner, the integrity of the seal will keep out the water and the cover should only have to be removed to replace the turbine motor.
Only the Snap-Tight cover needs to be removed to maintain the liquid probe or to visually inspect for any type of liquid or contamination. This eliminates the possibility of a person accidentally falling into the confined area and to have to lift the heavy cover.
The savings can be realized in low maintenance cost and no down time. Only one person needs to be there.
Leak detector can be removed - Line and Liquid probe testing can also be performed through the Snap-Tight opening.
