Leaking tank

DCPete27

I'm a "novice plumber" and have a leak in my toilet. I'm concerned that the spud should be more flush, but currently is raises the tank about 1/2 inch. This results in a tank that leans against the back wall, off-setting the two bolts that hold the tank down. This, in turn, results in a slow leak at these bolts.. (both have rubber washers on both sides..)

Do I need a "flatter" spud? Is there such a thing? I ask this because the other toilets in my house have much less room between the tank and toilet..

Thank you!

What brand is this toilet?

The AM/STD tank to bowl gasket is a thick one, pull tank and reposition the tank, tighten up in an even fashion, alternating from each bolt till it looks good, see if that fixes the problem.

Thanks for the info! Just to clarify: Do I want to tighten the two bolts so that the tank remains competely upright/vertical? Or is it okay for the tank to lean back towards the wall a bit? It would seem that the more it leans, the greater the likelihood of leaking.

But if I tighten it too tight, the ceramic may break....

Tighten up even both sides, no leaning, just snug them down, don't over tighten.

It invariably leans into the back wall.. Due to this I placed something between the tank and wall to keep it perfectly upright.

I've tightened, retightened, made sure the gasket was a good fit, over and over.. it will hold for awhile and then the leak begins.. Frustrating as anything! The washers are new, and it seems if I tighten more I may crack the tank..

I hate to do it, but I may be forced to call a plumber..

I appreciate your suggestions and time!

Is it leaking between the tank and bowl? It could be the flush valve gasket that is leaking making you think it is the tank to bowl gasket.
