I just had a new A-S Optimum Vormaxx toilet installed one week ago. It leaked from the left side bottom (where it sits on the floor) of the toilet, nothing horrific but enough to be a concern. A call to the plumber, shut off the water and flushed until the tank was as empty as it was going to get, water was still leaking out of the bottom. He came out and reset it this morning and now it's leaking from the right side . Again it's not gushing out but slow and steady. I've turned off the water and flushed the tank empty but water is still leaking out. What could be happening here?
