Light Green for COLD Water and Dark Green for HOT water
Cold water lines may have more insulation than hot water lines, otherwise they should both freeze unless there is some agent in the water.
By turning on the existing hot and cold water tap and running into a bucket, you will eventually get hot water out of one of them. The hot water is usually insulated. Cold water may also be insulated in the cold climate areas to prevent freezing. The taps are usually marked "H" or "C" or by color red and blue.
Odds are that the cold water lines to the faucet you are trying to use are shut off but the hot water lines coming from the water heater are not. That is why you have hot water but no cold water.
F, for frio (cold). Unfortunately, the hot water tap is marked C, for calor (hot), which could cause confusion. Fortunately, many taps use a color code as well : Red for hot water and Blue for cold water.
No.
If you have nothing coming out the faucet, your lines are probably frozen somewhere. The lines could develop leaks, so be watchful when they thaw.
we should put them in hot, warm or cold water
For cold water,start at the water meter, the follow it to the hot water tank for the hot lines. They are pretty easy to see, they are either copper or pex, or galvanized pipe.
Wash with cold water and the color will fade out
Supply lines- Hot and cold water for each sink, bathtub, Jacuzzi tub, and shower. Cold water for each toilet. Drain lines- one for each sink, bathtub, Jacuzzi tub, shower, and toilet.
I am not a plumber, but am in the process of installing a water line myself...and all of the research I have done says the water line should be hooked up to the cold water.
hot water takes the color away from the gumball first because the hot water is warmer than the cold water
