Client has us out today because the master stand up shower leaks when someone uses it. He had a plumber out who opened the ceiling where the water was leaking down through but did not make any repairs. The client noticed a crack in the shower pan but used a repair kit to fix the crack. When we tested the shower we could not get it to leak however when we simulated someone taking a shower you can see the flex in the shower pan around the drain. Found that the top side shower drain is just hand tight. Quoted the client and today we just went with replacing the shower drain and p trap. Water is back on with no leaks.
