I installed 2 brand new eco-Drakes and noticed a short "squeak" on flush. Not all the time, seems
to happen after the toilet has not been flushed in a while, like 5-6hrs.
Wondering if this is normal or if I need to do something to get rid of the noise? I noticed a few other
discussions on squeaky toto's after have been in use for a while, but these one are brand spanking
