Two Piece Toilet

I have an American Standard with tank tilting forward, which is uncomfortable. When I tank level, water leaks bolts. When I finally tighten the bolts enough, the tank is leaning forward. I notice that the bowl has two edges of the tank support, and the background is higher than before. When the tank is right, do not touch the ridge before.

This looks more like the tank is really the problem, it is slightly tilted causing the tank when it is properly seated to consider. The strap is there for a reason, to compress the gasket and once seated properly, do not leak. It is quite possible to mount the bowl incorrectly and did not leak because of the wax ring that conforms to the pipe and the bowl as the bowl is clamped in place by bolts . I bet if you put a carpenter's level in the bowl, back and forth and side to side, you are inclined. This has been a problem in an old house I used to live, only it was to end on the side a little, just enough to be a bit uncomfortable.I left unchanged because it is a rental, but you may consider up the gut and using a level to make sure it really is. I think every time he has been assembled, it was done by eye.Try level and let me know. Here is a link to the replacement instructions.

Try replacing the gasket asp

AS is a premium product, so lets assume no design error for the moment. did u check the floor for the level? When the soil is disabled in this field could tank in front. check to a store house where the toilet is on the screen to see if they're all the same. If this is the case for a change of Kohler or Toto brand new, I heard many good things about
