Evening all. I bought a wall hung wc pan online at the end of July and after extensive work to my bathroom plus doing my day job as a carpenter I finally got round to fitting it today. I've fitted the pan to a Saneux wc frame and gave it several flushes to see if it leaked. All good, no leaks on the flush pipe or the soil pipe. Came back to it a few hours later and there's a pool of water on the bathroom floor at the front of the pan. I checked the flush and soil pipes again and they were fine, then I noticed a drip at the front centre of the pan. Got a torch under the pan and theres a sort of lump near the front, like there was a hole made during manufacture that's been filled in. The water is coming out of that lump and trickling down and dripping onto the floor. I know there's a hollow inside the pan but why would it be filled up with water, does it mean there's a fault with the pan somewhere? Can't ask my plumber, he's gone away for Christmas. Any ideas?
