Query: American Valve - Unsatisfactory Products, 3 Failures

American Valve makes their PVC products in CHINA!!! Unsatisfactory Quality control. I've had to replace the same 2" valve...3 TIMES!! It involve digging up my water main to the house each time. The failure occurred in the same spot each time....on the valve stem housing which supports the handle....about a 1" crack. I'll never buy a product from them again. Sent the crappy piece of PVC in a box to the CEO!!
