    "If its the overflow pipe thats leaking, this suggests to me that the ball valve and float is set too high and that the water level is reaching the overflow outlet. This has to be the first thing to investigate. Quite simple to gently bend arm of ball valve so that float stops supply lower down the tank. I usually set the level about 50mm below the bottom of overflow outlet pipe. Also check that its not leaking outside of the fitting. This would suggest that the overflow union adapter has not been tightened sufficiently to make a seal."

    "Looks like the fitting wasn't done properly, the best bet is to refit that bent part make sure is fitted tight or glued depending on what the plumber used. if it is plastic, it's usually pushed and fit sometimes they need little things like inside rings to hold it tighter. A plumber would know all this."
