The bedroom floor in our 32 re started getting wet and I found the bathroom sink drain tubing connections were all extremely loose. These junctions have screw together connections. I was able to tighten each about one and a half full turns before they were even somewhat tight. I'm sure they should not be this loose. I checked those under the kitchen sink and they were all loose too. Its like someone fit the pipes together but never tightened them. Anyone know how much force should be applied to seal these fittings? Are these types of fittings used elsewhere, like in the underbelly ?
