If Y, note date. YIN <br /> Is each tank protected to prevent unauthorized access? YIN <br /> Note if the tank is a bladder (B)or hydronuematic(H)tank. j <br /> Is tank or piping/valves/man-way/sight tube/internal bladder at a tank leaking?YIN <br /> Did the system lose pressure below 5 psi(Le lose electrical power;break a water line; <br /> lose a pump; run out of water). Is pressure holding at the tank? YIN <br /> Are there any connections to irrigation, fire, industrial piping that could be cross- <br /> connections? (backflow,devices removed, need repair, need to be installed) YIN <br /> Is pump cycling on and off, is pressure tank holding pressures, is tank <br /> waterlogged (lacks air space in the top 1/3-1/2 of the H tank)or has a hole in the <br /> bladder of a B tank? YIN <br /> Has any work been done on the system?(repair water line,install/replace/repair a component;use of <br /> a pressure washer;serve water for an event that used more water then normal) YIN <br /> Is tank protected with a backflow prevention device?
