Place sign near cooling tower stating need. Working on sign for the area. Open valve V-6 for 5min or so to bleed out air. Not a safety problem. No action taken.
Air blocks water from flowing at full rate causing low flow measurement reading.
Costly to replace. Chem stores needs to supply these or we should purchase these. The nut that holds the knob on the high pressure valve to the manometer fell off from the vibrations of the pump. Nut was replaced and tightened so it wouldn't fall off again. Pumping B - Amp Meter switch looks just like power switches.
