Need some advice, both Kohler toliets on the second floor have been drain slowly and or backing up. Both toliets also are leaking. The toilets are only 5 years old. Since I am the first owner the toliets didnt not get much use for the first two or three years I have shattered my heel bone so I had to call a plumber to clear the drain and or fix the toilets. The plumber said the toilets are junk and to fix the drainage issues i should replace the two toilets and maybe all three with American Standard Cadet 3. I do have the same toilet on the first floor which is still working fine. Funny thing is the toilet on the second floor is getting alot of work since I have been living on the second floor the last three months
Thanks in advance
Are Kolher toilets junk and should i get a second opinion?
