Bladder #1 interceptor pit checks (also known as the weir)

• Is the Bladder #1 interceptor pit/weir dry? If water is present, do a pH check with calibrated instrument to confirm pH between 6.5-9. If the pH is between 6.5 – 9, the valve can be opened to drain down. Valve to be closed following drain down. (Record Ph in notes)
