Called out today due to the men’s bathroom upstairs in the office leaking from the back onto the floor. It was leaking from the flange, which had a wax ring on it, as well as a rubber gasket which is not supposed to be used together. Removed the old wax and gasket and installed new wax ring with horn and re hung the wall hung toilet and fastened the 4 bolts. While putting back together, noticed a small drip at the toilet spud. Tightened it up just a bit, and it got worse. Removed and saw the rubber sealing gasket for it was completely gone which is why is did what it did. Replaced that toilet spud after rehanging and tested. No more leaks. Advised client to not use that toilet for at least 48 hours.
