About 3 years ago I came to this site looking for toilet recommendations.
I ended up with the Toto RF Drake CST743S and the Toto EL Drake CST744S.
I love the Toto's toilets. I have no problems with rounded front but the elongated one has given us some problems. Namely the flushing power. Sometimes it fine, but most times it seems like there's no force behind the flush. Often I will hear noise coming from the tank. I know I'm not being super clear about the problem - I was just wondering if the elongated fronts are more prone to be problematic. Thanks in advance.

Also, do the rounded fronts and elongated fronts use the same tanks?
