Either on the underneath side of the lid or on the back of the tank inside there should be a model number. Possibly on the underneath side of the tank also.
How do I find out an answer to a question about toilet repair? I have a crack in my tank and I want to fix it. It is ceramic.
Inside the tank, usually on the back wall, there will be a number impressed into the porcelain. This is the tank number for a two piece toilet, or a model number for a one piece toilet. It's usually a four digit number, sometimes preceded with a K- (example: K-1234). Sometimes this info is repeated on the underside of the lid. Usually the lid also has a five digit number, which is the lid number. All of these numbers can help you find the replacement parts to repair your toilet.
You should be able to take the old tank off and mesure the distance of the mounting bolt holes and mesure the diamiter of the water hole then go to home depot and mesure some of the tanks they have. I diagree with the previous answer. By the way, it's spelled: measure. Anyway, if you have a 1.6 gallon toilet tank, you should replace it with the same brand. Different manufacturers tanks will NOT work with just any toilet. If you have the old style toilet e.g. 3.5 to 5.0 gallon tank, you would have to find a junk dealer who would have the exact same type of tank.
I find it easiest to bolt the tank to the toilet first, then sit the whole unit on the flange.
The width of a toilet tank can vary in size. The average width of a toilet tank is about 18 inches.
in most cases yes, if you know the brand. the model number is usually stamped on the lid or inside the tank.
They are called tank bolts.
