Went to run a bath for the kids and presently the water won't shut stale....what do I do? HELP please.......thanks
Answers:    cut bad the main supply rotten coming from the well....cut the power bad of your water furnace so you won't burn up the heater elements(assuming the hose heater is electric) until you amount out why you have the problem.
If it's hot sea, shut it off at the river heater. Cold sea, shut it off at the foremost cut off inside your house, until you can achieve more information on how to repair the faucet,
