Inspection hatch for Tank Safety Shower Water Testing: We have introduced a special smaller hinged inspection hatch as an option to make it easy to test and maintain the water quality in our Tank Safety Showers. Normally, the heavy lid of the water tank or a larger inspection hatch would have to be removed. In many cases this can be a difficult to achieve and very time consuming. With a small hinged inspection hatch the water can be easily accessed and tested through ‘dipping’.
