The toilet at our camp is not flushing properly. When flushed, the bowl
will rise, but the whirlpool will not form. After a few minutes, the water
level will fall but the bowl is never flushed. If I manually cause the tank
to fill to a higher level than normal and then hold the flapper open for the
tank to fully drain, the whirlpool does form and the bowl clears. This came
on suddenly. It looks like I have a partial clog. The plumber's helper
does not seem to help. I suspect female trouble.

Will the kind of snake used for sinks and such work in a toilet or do I have
to buy one of the special ones for toilets?
