we are having issues with our upstairs shower so while we are trying to get that worked out we are relagated to a never used downstairs one that is a tub/shower combo. Realized today as I stood ankle deep in water that there must be a clog somewhere. Got my handy dandy zip thing, unscrewed the drain cover and tried to use it...can't get it in much at all. So weird. Tried a few times but obviously there is some configuration that doesn't allow for it. Next I tried boiling water/baking soda/vinegar/boiling water. Still seems clogged. Have always heard not to use liquid plumber/draino. I'm about to regardless. Any other suggestions?
