I may have a possible solution for the stalling issue on air diaphram pumps , and It would also be an added safety measure to turn off the pump from the roof . My background is in irrigation , a large part of my fall business is blowing out sprinklers , I use a 125 cfm tow behind compressor , pushing 100 psi constant pressure. Now irrigation valves are a normally closed valve , they are rated for 125 psi . My Idea right now is theory . I have seen remotes , like the keyless remotes for cars , an irrigation valve ( old style toro 3/4 in would be best its bullet proof) and a 9 volt battery . Just prior to the air supply to the pump plumb in a tee ,it could be all on quick connects, the irrigation valve would be off that tee . Wire up the remote and battery, when the pump stalls simply push the remote , it would blow off your air pressure , reset the remote and you have pressure again. Drop the hose , push the button on the remote and you have no air pressure , the pump shuts off . I just havent had the time to find the remote stuff . The 9 volt battery will work even though the valves call for more , we do this too test them in the yard. I havent had a chance to make one as of yet , I dont have heat in my shop . This may be able to save a couple of trips back to the truck or to shut off the pump quickly. A remote could probably be wired in to the electric pumps to turn them off in an emergency. Irrigation valves are about 20 bucks retail , the remotes cant be that expensive I would think . Matt
