The commode in my bathroom has started running again ... it will just
run a short time, like some of the water has leaked out and it is

back ... what else would cause this problem? At the price of water
here I don't want to waste any. Thanks.

The flapper valve may be trying to deal with a corroded out of round
seat, valve seat, that is. The fix would be to replace with a more
complete assembly which could include most of the hardware in the
tank. Drain it, inspect carefully, then look for an assembly
compatible with your unit. Good luck.
