When downstairs (main floor)toilet is refilling pipes in basement shake uncontrollably & sink faucet in same bathroom turns on. SO! I read about the problem stemming from toilet tank. In the meantime I turned the pipe valves in basement thinking I was bleeding air out of lines, it did nothing so I turned them back to original position. Now the hot water valve is leaking ever do slightly BUT NOW THERE IS NO WATER WHATSOEVER in upstairs bathroom!
Help!

Sounds like you've disturb some settlement buildup in your pipe walls and mount its flagging your cartridges and supply lines. The solution is to flush the lives , pull the carTomtridges and cleaned them
