Thread: Toto Aquia II Dual Flush leaking - help!

  1. #1

    Exclamation Toto Aquia II Dual Flush leaking - help!

    My contractor installed an Aquia II Dual Flush Toilet last week. It seemed to be working fine, but now it is leaking from the tank. When we flush the toilet water spurts out from the bottom of the tank onto the part right behind the toilet seat (right where the TOTO logo is.) It wasn't doing this before. Please help!! He is experienced in putting in regular toilets, but not Totos.

    The Aquia tank needs to be installed evenly.
    It takes a little more time tightening each screw, just a bit, and then the other just a bit.
    I would guess that a screwdriver would fix it for you.
    We have over 150 out there now that are in operation.

    Default Thanks, Terry!

    I'll pass this information on to my contractor, and keep my fingers crossed.

    Thanks for a great website, Terry. My contractor also had difficulty installing our Eco-Drake. (He installed 2 of them, one leaked from the tank, the other didn't.) After I showed him what you advised on your Drake thread about sanding and the 3-point contact, he was able to fix the problem. We had thought the Aquia II was done correctly, however.

    Wish you had a branch in the SF/Bay Area!

    Default Another question

    I followed your suggestion, tightened both screws gradually, and so far, so good! I was surprised by how loose the screws were.

    Will the screws continue to loosen and have to be checked regularly? My old (1986) toilets were terrible flushers, but they never leaked, so I've never had to think about it before.

    Thanks!

    I think they were just loose.
    Now you know how it works.
    You should be good.
