Hi All,
I had to replace the fill valve on our Toto ST743S today as the original started to make howling noises which I suspect means it is on it's way out. Anyway, once I completed that project I noticed that upon each flush a drop of water would build up and occasionally leak from the bolts that hold the tank to the bowl )It's leaking from underneath the tank so I can run my hand on the outside and feel moisture). I assumed this has been happening since our plumber installed it a few years ago since I could see a tiny bit of rust on one of the washers. I first tightened the bolts down about 1/4 turn but that did not fix the issue. I decided to not tighten the bolts anymore as I could possibly crack the tank or bowl turning a small issue into a mess since we only have one bathroom.
I decided to simply spread some clear silicon on the around the metal washers to see if this stops the tiny leaks. My two questions are:
1. Was it ok to use the silicone or was it a bad idea?
2. What causes this? It's not a constant leak and only happens when I flush.
