Teacher: Now, understand the problem? Solve this instance: On one unit the brass casting leaked as soon as the water was turned on. With that record, no sense even trying the second unit, Update: revised to 3 star based on vender response - furnished full credit without need to return & then I installed the 2nd valve, which operates without any sign of leakage
