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.
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.
To remove calcium deposits from cold water lines, you can try using a mixture of vinegar and water to flush the lines. First, shut off the water supply, then pour the vinegar mixture into the lines and let it sit for a few hours before flushing with clean water. You may need to repeat the process a few times for stubborn deposits.
To properly install the hot and cold water lines under the sink for efficient flow and temperature control, follow these steps: Shut off the main water supply. Connect the hot and cold water lines to the corresponding valves. Use Teflon tape on the threads to prevent leaks. Ensure the lines are not kinked or twisted. Test the flow and temperature before securing the lines in place.
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.
Hot water may be present in the cold water line due to a phenomenon called "cross-connection," where hot and cold water lines are connected. This can occur in older plumbing systems or due to faulty installations, causing hot water to mix with the cold water supply.
If hot water is coming out of the cold tap, it may be due to a plumbing issue where the hot and cold water lines are crossed. To fix this, you can check the plumbing connections under the sink and ensure the hot and cold water lines are properly connected to the correct taps. If the issue persists, you may need to consult a professional plumber to resolve the problem.
A hot water heater is designed to supply hot water to faucets, not cold water. It is not possible for a hot water heater to siphon into a cold water faucet. Each faucet is connected to either the hot or cold water supply lines, which are separate in a plumbing system.
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.
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.
