It is a low pressure rain collection system, gravity fed. There is a 500 gal tank about 1 ft above the valve. I just want to know if there is a way to tell if this particular valve is closed by looking at it. Thanks
I have a PGV-151 - Hunter PGV Series 1.5 inch threaded Inlet/Outlet with Flow Control I manually opened the vale to drain it for winter. I cannot figure out how to manually cloe it. The documentation says "1/2 turn opens the valve". I have turned it both directions, but I don't see how to know if it is closed. Is there a handle/knob position that indicates whether it is closed or not? http://www.sprinklerwarehouse.com/ProductDetails.asp?ProductCode=PGV-151
