Sammie shut off his 2" lowes union valve, disconnected it for a sec, the ball flew out and a hammerhead was blowing out a 2" stream of salt water across the room. Not so sure the lowes valves do the same work as these.
THe nice thing about the GF valves, they always operate. Never get jammed up from CA and crud and operate so smoothly, you can use them in place of gate valves for adjustment.
