Toilets, Sinks, Showers, Tubs and Disposals - leay flush tower

Hi - I have a toto ultra-max toilet with a g-max flush tower. I have 3 of these toilets and been using them without problems for 5+ years. All of the sudden, I got a leak on the tank where the g-max tightens to the tank. I thought, that's simple, just tighten it. It didn't work. After further inspection, it appears that there is only a leak when the line is pressurized. I don't think it's leaking due to the gasket or the tightness of the nut holding the flush tower on. It seems like it's internal somehow to the flush tower. Anyway, I was hoping that someone may have had a similar problem, so I'm looking for advice.

Thanks for any you can offer.

You might want to pull the tank off of the toilet and inspect for cracks and/or distorted components of the flush valve assembly.



I have only had one problem with Toto's and it was a defective tank to bowl gasket they gladly replaced free of charge.



Call Toto's technical service, they will try to determine what it is and probably send out replacement parts free of charge.
