It never fails...always an unexpected expense right before the holidays. OK plumbers...not to be too graphic...I have a toilet that is partially clogged...the water fills up close to the top, does not overflow, then drains down....but never completely empties the bowl. We have plunged numerous times, to no avail. There is nothing yucky left in the bowl, so I have time to try and fix this myself. Any ideas? My kids assure me there are no Barbie Dolls or baseball gloves stuffed down the toilet.... I have heard you can't put Liquid Plumber or anything else like that in a toilet cause it will eat the wax ring.... TIA!
