I have an older style toilet. It has the overflow tube in the middle of the tank and the ballcock assembly to the left as you look at it. It was constantly running and in order to stop it temporarily I had to physically lift the rod that holds the bulb.
I figured there was a problem with the entire ballcock assembly so I replaced it yesterday. Now when I flush the toilet the tank fills and the ballcock unit shuts off. However, after 5 minutes or so a slight "hiss" type sound starts and in order to get it to stop I have to physically lift the floater rod. When I let it go the sound starts again.
Am I getting a slow leak around the flapper assembly? It would seem to me that the reason this would happen is that water was slowly leaking out which makes the floater assembly drop which in turn would trigger the fill water to start flowing again, however slowly.
However, if that was the case why wouldn't the tank fill back up to compensate and then stop the "hissing" sound at least temporarily?
Thanks
Note: As a followup, after I posted this thread I turned the water supply off and the tank is slowly losing water. Obviously I have a slow leak which would mean something is not sealing properly. Should I start with a flapper replacement and can you do that without replacing the entire overflow tube assembly?
