: To completely flush my 2nd floor toilet I must hold down the handle for about 10 seconds or else the flushing action looses momentum and stops. But, my ground floor toilet doesn't have this problem - it flushes normally with just a quick press of the handle. I checked inside the 2nd floor toilet tank and it looks like the rubber drain stopper is prematurely closing up the drain hole. Is there anything a novice like me can do to correct this inconvenience such replacing a part, etc?

Russ,
Do you mean:
It doesn't flush everything away?
or
It doesn't use all of the water in the tank.

Most newer toilets do not use all of the water in the tank. Only a portion of the water is used during the flush. The rest is used to mantain a higher "head pressure" in the tank. By stacking the water higher, more pressure is built.

If you mean that the flush is not flushing away everthing, then perhaps you have a replacement flapper that has not been trimmed right.
