Rescue at the last emergency

Moving to the bathroom should be equipped with a beautiful new shower faucet. However, save in the wrong places - as diverter was made of cheap plastic that the water pressure is not held level. Water ran out of the shower and the hand shower. Actuating the valve was revised directly by the water pressure. Since this part was right, a Umstelllventil with quality. But the massive weight suggests that one thing has bought good. Connected and now the valve is a clear target where the water comes out. No independent regulation more. Everything shipshape! Class!
