When I flush the toilet in my extra washroom it now leaks big time from somewhere between the water tank and the base. A seldom used two piece crane toilet. I tried tightening the two bolts connecting the tank to the base but no help.
Any ideas on the problem, or the fix?
 
Sure, you'll find a foam seal between the tank and bowl. You'll need to take them apart and replace the seal. They are standard sizes so you should find a replacement seal ok. You should find two bolts holding the tank at the tank bottom.

If that doesn't work find the girl next door and use hers.
 
there is a wax ring that goes between the toilet and the floor. Remove bolts a take a look, but make sure you turn off water then pull to flush then drain remaining water.

not always foam. Last 10 or so I've installed have a thick donut type rubber gasket (like 2" thick).

Also, in some, there are rubber washers on the inside of the tank on the mounting bolts. Overtightening them can split them as well.

What I'd do is:

Turn off the water
Flush the toilet to empty the tank
remove the tank by removing the nuts on the tank bolts
Inspect the gasket between the tank and the toilet bowl
Remove the bolts leading from the tank to the bowl and check the washers.

You should be able to find replacements in the plumbing repair section at Homo Depot/Rona/Lowe's

After re-reading the original post: it only happens when you FLUSH? Then it has to be the gasket between the tank and the bowl because the flapper seals that area normally and only allows water through when you flick the handle......
 
There are three seals in a two piece toilet. One each on the inside of the tank were the screws go through to tighten down the tank to the bottom piece.

The third is an "O" ring that the top is seated into as it is placed into position over the toilet bowl. It is usually a rubber compound and prevents leaks between the two pieces.

I would recommend replacing the screw seals as this is the most likely place for a leak unless, of course, the tank is cracked.

Good luck.

Given that the OP says that it only leaks when he flushes it is unlikely to be the screw seals.
 
sounds like the tank to bowl seal, you can buy a tank to bowl kit which includes new brass bolts, nuts, rubber washers for under the head of the bolts, and a new seal for between the tank & bowl.
 
It can also be a gummed up tube from the filler valve, i.e. the path of the
water let out of the filler valve is obstructed, so it splashes out from the top of
the filler valve and runs down the tank.
 
wc leaking @ tank to bowl

if has been left dry for a while (the tank that is) the 2 gaskets under the brass bolts fasting the tank to bowl has dried out , you can buy a tank to bowl kit and replace them , if all of a sudden this wc has started leaking there is more than likely a cracked tank , someone could of been sitting on it and leaned back and cracked the tank , thus maybe replace the whole wc with a more modern one low flush maybe , if none of the above fixes seem to fix the problem take the lid off and flush and watch whats going on in the tank sometimes the bowl fill tube has come off and will spray out the tank , When you fix the problem let us know what was wrong and how you fixed it . ;) Bart
 
Bought and installed a kit with new bolts/washers and large centre gasket.
The bastard still leaks from the same spot!! Is still coming out under the tank where it joins the bowl, when it is flushed.
How about where the flapper unit or downspout screws into the bottom of the tank? Anything there to consider?

Don't want to replace the whole unit unless I have to - have never done that job before. But am getting close to it. :(

Are you sure it is not running down the bowl, when it is flushed. Take the lid off the bowl and observe if water splashes out of the top of the filler valve when you flush.


If the problem is there, you can buy a new filler valve assembly.
 
Talked to a friend who says don't bother with the rubber gasket, get a good sized wax one. Looks like that was what was on it originally anyways.
Will try that tomorrow. Who knows, will see :(
 
Alternate when tightening the tank bolts so both sides come down evenly. Get some to push down on the tank to make tightening easier.

replacing an entire toilet is easy and if you get a low flow version you'll get some of it back from your local munincipality......two bolts, a wax gasket, and a water connect and you're done....shouldn't be more than 20 minutes....
