Hi folks. Last year, I was in my basement when water started pouring from the ceiling. Luckily, it's a drop ceiling. The hex nut was completely loose. I tightened it by hand. Started leaking the next time someone stepped into the shower. The nut was loose again. I assumed it was due to not being tight enough. However, I didn't A) know how tight it should be nor B) what to use to tighten it. It's large and I don't have a wrench that big. I then put a screwdriver into the slots on the hex nut and took a hammer to tighten it. Good for a couple days, and then loose again. Like anytime someone steps into the shower, it loosens. Someone told me to loosen it, so I could pull the drain up at the shower. Place plumber putty between the drainer piece and the shower. It would help sill it AND extend the drain up a hair, to pull the hex nut tight. Ok...that worked or so I thought. Fast forward to today and here came the water. The drop ceiling tile was soaked and moldy. So, it had been leaking a while, meaning my old "fix" didn't really work. Can anyone help me? This is not mine, but found on the net, but my hex nut is like this, where it is leaking.
