Hello, just wondered if anyone has any ideas....got a persistent drip of water coming down a light fitting on the ceiling below the upstairs toilet which was put in a couple of weeks ago. There is no water on the bathroom floor, no obvious leak from waste pipe connection. We removed the toilet last night and the leak stopped completely so assumed it was coming from the cistern down the screws and we hadn't noticed it dripping. Put the toilet back in and the dripping has restarted....the toilet has not been flushed and the water level in cistern has not gone down. The valve on the water-in pipe is off. The pressure on the boiler is stable so doesn't seem to be a separate leak in the heating system. (and as I said, stopped when we removed toilet) It is a bit perplexing! Just thought I'd ask on here if anyone has any ideas before we start pulling up the floor/cutting ceiling!! Thanks!
