See the attached PDFs of a new product found in the field and used for BONDING POOL WATER. I have seen this new product in use and have now realized that most were installed improperly. Some of the ones I have seen where installed just downstream from the pump above grade. Look at the attached installation instructions and notice that the fitting needs to be installed 3” below the water level in the pool to be effective. So if you install this fitting as a water bond to comply with 680.26(C) it will need to be install in the ground below grade. The ones that I have seen installed properly used a sprinkler type in-ground junction box (brooks Box) to access the fitting. Hope this helps and saves you a re-inspection.
