Just installed new american standard cadet 1.6 gpf toilet on 12'' rough in. now my toilet tank is 2'' off wall and concerned about tank when i sit back breaking or cracking flooding my house.what can i do ?

Toilets wear out from mineral deposits. Fixn may cost more then new. Googl used commodes first

American standard cadet III is a nice flushing toilet that is reasonably priced. The tank is smaller than the cimarron. Toto also makes good flushing toilets that would fit your needs, but you will pay more for it too.

Inside the tank on the back wall.

Sorry for problem with new toilet.
You say water is leaking out of the bowl?

Toilets have 2 parts:
1) Tank: where water is stored for the flush and is sealed with a flapper.
2) Bowl: where water flushes down.

a) If tank is leaking water, then flapper is suspect. Replace flapper and see if that works.
Lift up flapper and run finger around rim to see if there is a rough spot that would indicate flush valve is defective, and needs replacement.
See typical flush valve

b) If bowl is leaking, that is very unusual and would indicate a crack in the porcelain.

If installer sold you the toilet, it is his responsibility to make good on product.
All products are guarantee against workmanship flaws.

I would say that there are no concerns that are not a concern with most of the new toilets of today, regardless of tank size it should always be designed to hold more than 1.6 gallons of water. The key is to find a toilet with the largest flush flapper as you can allowing all of the water to be used quickly and effectively. hope this helps.

The reason the tank doesn't sit down on the bowl is cause it's not supposed to just sit flush from the start. Your suppose to tighten the tank bolts down in order to get a water tight seal. There is also these little rubber " U " shaped things that sit on the porcelain lip on the back of the bowl thats what's there to protect it from cracking when you tighten the bolts down. Just place 1 on the right side and the the other on on the left side. and tighten down 'til the tank touches the bowl.

Sounds like your flapper isn't sitting properly. Put food coloring in the tank and wait a bit - see if it goes into the bowl for a definite answer. A new flapper will cost about 6 bucks. Good luck.

Hrm, I see what you mean and this may be a bit late.

The 14" rough in is not standard (as in 12") and the depth (from the back of the tank to the front edge of the bowl is your concern here?).

Kohler also has a Sterling brand with the Windham model. This will sit on the 14" rough and measure less than 30" from the back wall.

You could also go with a Toto ($$$ concerns) as they have a unifit system that allows for adjustment from your roughed in closet/toilet flange. It basically mounts to your flange and then sets back 2" or 4" depending on which model Toto toiler you are installing. The Soiree-?sp may be your best bet for depth concerns, but not so good for your wallet.

if you have a 10" rough in your house you can not install a 12" rough toilet. but if you have a 12" rough in your house you can install a 10" rough you would just have a 2 inch gap between the toilet and the wall.

the rough is measured by measuring the middle of the sewer hole. that your toilett sits on. to the back of the wall this is important because the tank sits behind the toilet. if the tank is too big then the toilet wont fit over the sewer hole.
your house shouldnt have a 10 inch rough unless its about 90 to 100 years old most home's now days go off a 12" to 14" rough.

if you do have an old home you can order any 10" rough toilet at a plumbing supply store. or lowes. they probably wont carry them in stock though because 100 year old houses aren't very common
