[quote=Dale;224639]Hi Mark,
Did the valve strip off of the threads or was it just barely screwed on so that a bit of movement knocked it loose? Just curious. QUOTE] No..no..the valve hasn't failed. They are designed this way. I just didn't know it. In this way, the valve can be fully disassembled and serviced. You can remove the ball portion, relubricated the o-rings...it's very nice. It does, however, mean that the ball valve will only support pressure in one direction WHILE THE UNION IS DISCONNECTED. That means that there is a definite "right" and "wrong" direction to install them. I think in this case, he had the union disconnected on purpose because he was servicing the pump. That's why it is there. It all works safely, as long as you have it installed the right way 'round. I just spent an hour or so reversing 12 of my 14 valves because I thought the arrow was a flow direction as well!
