Overflowing toilet question

[Dave DesRoches]

Had a toilet overflow today. Plunged it out, but the odd thing is:

Water fills in the back tank and the float rises, a bit beyond the water line level. However, the water continues to run, even though the float is high. By picking up the float just a slight amount, the water shuts off (?) Not sure why it doesn't shut off on its own, given it's high (slightly beyond water line level). Trying to avoid calling a plumber, if this might be a simple fix, but by the same token, I want it permanently resolved, having already cleaned the basement once from the overflow.

Thx in advance,

The probelem is that the shutoff valve operated by the float assembly has failed. There is usually a simple rubber seal and seat which can be replaced after unscrewing a retaining cap. Turn off the water source and begin disassembly to see what you need. If your box store doesn't have it, a plumbing supply distributor likley will (if you're lucky enough to find one that sells to the walk in trade). Good luck.

Sounds like 2 un-related problems.

There was a clog in the bowl (toilet paper?) and plunging cleared it. See if that problem recurs.

The overfilling of the tank might be correctable by an adjustment or rebuild of the ballcock valve or replace it. Too many variables to list here but there's a super resource at:

the valve has a washer in it.. the washer is not making good contact to close the valve... when you pull it up then the washer is pinched real tight and the water stops.... try replacing the washer in the valve.... if that does not work then go to hardware store and buy a flow master valve for about $5-$6.00 and install it and you will not have any more troubles.....

Sometimes these old toilet valves just get old. Bend the rod down a bit on the float so that the float will shut off the water sooner.
