I have two toilet questions about different toilets on opposite ends of the house. 1) I have a toilet that will not flush! The water goes round and round, but the flush never happens. Plunging does not help either. Note: I took a bucket of water and dumped it in the bowl and it flushed with no problems. Any ideas? Bad toilet? 2) The bathroom at the other end of the house won't flush either. however, one pump of a plunger when it is flushed and it flushes normally. Ideas? No slow bathtub/shower drains. The toilet in the middle bathroom flushes right every time. Thanks for the help!

Hi, I have an unusual issue with my drain. My upstairs shower and my downstairs kitchen sink share the same drain and roof vent. When I run my downstairs dishwasher or my kitchen sink at full water volume, I have no problems with the sink drain but when the upstairs shower is running and especially when the same upstairs tub is draining, the kitchen sink would fill almost to the top and sometimes overflow. I would like to know what would cause that? I snaked the kitchen sink with a 1/4 inch 25' snake and I think I hear the snake go up the drain towards the upstairs not down. I also snaked the upstairs shower drain with the same snake and nothing came out. Do I need to go to the roof vent with a longer snake? I am confused. Please help.
