one of our toilet tank's bolt has been leaking, so i drained it and let it dry.

it is now completely dry. i was wondering if there are different sizes of toilet tank bolt or if they are all the same sizes...

newbie here, appreciate some advice.

thank you.

I have replace quite a few toilet tank bolts they are all the same size Just make sure you get them tightened evenly, and while you are at it you might want to replace the tank to bowl gasket.

Be careful removing the tank bolts. The last ones I did were rusted and had to be removed with the grinder.

spend the extra dollar or two and get brass or stainless to put back. much easier off next time:thumbsup::thumbsup:

Remove the bolts (cut if needed)
Remove tank to bowl gasket
Take bolts, the bolts rubber washers and the tank to bowl gasket to the store and buy replacement parts.
Reassemble tank with new bolts and gasket. Tighten bolts evenly and do not over tighten.

Sometimes I'll put a little pipe dope on the washers inside the tank between the washer and the porcelain. On the tank gasket, too.

Nowadays most tank bolt kits are generic.

The normal sequence for assembling the parts goes: bolt (head), rubber washer, tank, metal washer, nut, bowl flange, metal washer, nut. The kit may have additional parts and a diagram of where to put them.

As you tighten the lower nut, the center nut may loosen and need more tightening against the bottom of the tank.

Sometimes there is not enough space between the tank bottom and the bowl flange for the nut in between. The tank must not balance on the nut since any shaking of the tank with the hard nut in between will crack the toilet flange or the tank bottom. Then you must either omit that nut and count on the tightness of the nut further below to seal the bolt properly above, or sand the face of the nut so it will be shallower and fit.
