It may be caused by your faucets needing replacement cartridges, if your faucets are single valve type. Note: I learned of this several years ago working with the Moen technicians (they willingly helped diagnose the problem.) This may seem counter-intuitive but when a house is built the installers will choose one manufacturer for faucets, although many different styles, within the house. If they install a single handle type the seals on the faucet cartridges start to deteriorate and begin to "bleed" the hot water into the cold water lines and visa-versa. If you replace only one of the cartridges the problem will migrate to another faucet, within a short time. So I would suggest replacing all the cartridges at one time. Since I was in the trade buss. Moen actually paid for the replacement cartridges if I agreed to send all the old ones for study. (I doubt that Moen will do it for you.)
the pipe with the hot water will.]The piping with cold water as many hydronic systems are over 100 years old and the piping looks as new as the day it was installedAs long as thermo stress and velocity are taken into consideration hot water lines can last longer then their cold countter parts as cold piping becomes more brittle over the years
This is probably a pressure imbalance problem or you have air in the lines. see the related video link provided.
Because someone switched the lines or labeling.
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
the hot water valve shut off valve shuts off the hot water. The cold water valve shuts off the cold 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.
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.
Light Green for COLD Water and Dark Green for HOT water
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.
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.
if the water is cold enough you can die and if it is too cold, you shiver and may be sick
Hypothermia.
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 backfeeds from water heater into cold water lines due to expansion of hot water. Usually occurs when a faucet hasn't been opened for awhile, letting hot water backfeed through system.
if someone put in a hot water tank they may have the lines switched.
Get a plumber to trace your cold water lines to find out where the heat is getting into the line.
