The valve needs to be closed when the pressure gage is removed. The hose assembly consists of two, 10-foot long by 4-inch diameter water hoses with quick disconnect fittings, dust caps and plugs. Located on the top of the tank, the pressure relief valve is manually operated to relieve trapped air. It is opened and closed with finger pressure. END OF WORK PACKAGE      5     4 3 2 1
