: The toliet is slow to drain, filling up to almost overflowing then drains, but very slowly and not flushing the contents fully. Also, after pushing the handle, at times a 'banshee' noise would emit-sometime for a second or so, other times longer rivaling the call of the wolves. If perhaps something maybe partially blocking the drain, how does one 'snake' the toliet drain? Help.
If the toilet was flushing good and all of a sudden this problem began, the trouble is more than likely a restriction in the trapway. If a plunger will not correct the problem, buy (General makes a good one) or rent a toilet auger from a plumbing supply house that rents tools.
The odd noises could be from the toilet fill valve which may need replacing.
Good Luck. e-plumber
