Cold faucet runs warm water for 5 minutes
Author: mculley11 (WA) In some bathrooms and kitchen when I turn on the cold water it's hot for about 5 minutes before it turns cold. I'm obviously wasting a lot of water by running it for so long. Also noticed that the water in my toilets are warm.

Author: hj (AZ) There can be many causes. Some are correctable and others you have to live with. It would have to be checked on site by a plumber.

Author: NoHub (MA) You have a cross connection somewhere. A Good Plumber should be able to find it quick. could be a washing machine...a shower valve....see a lot of hot and cold hose connections twined together from a mop sink "going to a hose spray" do it to. Good luck.

Author: Wheelchair (IL) You can neutralize the system by flushing and feeling the cold lines as they begin to heat up. Hot water pressure can be 2-5 lbs greater than cold water, so if you have a bad check valve or cross connection in your pipes, this can happen. Best Wishes
