Why is hot water not running but cold is?
If hot water pressure suddenly stops entirely but cold water flow continues just fine, then a control valve may have been left closed, or a valve may have failed internally (appearing to be turned on but actually “off” internally due to a broken valve stem part), or a valve or pipe elbow may have become partly blocked …
How do I reset my water cooler?
To do a reset, drain a few cups of water out of both the hot and cold sides of the water cooler. Then turn the switches in the back of the cooler off. Unplug your water cooler, and leave it unplugged for 24 hours. When you do turn it back on, be sure to turn the back switches on as well.
Why is cold water coming out of my hot water heater?
Assuming no one has shut down the temperature adjustment on the heater or partly shut down a valve, and that you have cold water coming out fine on cold faucet setting, and that the outgoing pipe from the heater stays warm when water is flowing from a hot faucet, then sounds like a blockage in the heater.
Why does cold water not come out of my faucet?
If you do not hear water coming into the tank (and incoming cold water pipe will get colder) or have water coming of the hot faucet then a flow blockage is occurring somewhere. Course, if the existing “hot” flow equals the cold then this is not a blockage issue. If the above does not help track it down, then you need a Plumber.
Why does my washer fill with hot water on the cold setting?
Some of these switches are programmed to sense when the water supply hoses are reversed. If the switch on your washer sensed this in error, it would fill with hot water instead of cold. You may need to replace this switch. If you have a different type of washer or need more help, resubmit your question with the full model number of your washer.
Is it safe to mix hot and cold water in a water heater?
These mix cold and hot water together to reduce the temperature of the hot water to safe levels. Some places install them at each faucet, others install them at the water heater itself. Turning on one faucet would just give cold water no longer how long it ran.

Why does my shower have hot and cold water?
If the other faucets around the house do have hot and cold water, then the problem is most likely the pressure-balancing valve in your shower. Pressure-balancing valves regulate both pressure and the ratio of cold and hot water that flows out of the showerhead.
Why does cold water come out of a toilet faucet?
A possble cause, assuming pretty much full flow of cold water from the hot faucets, depending on plumbing arrangement, is a one-way valve in a toilet anti-sweat mixing valve stuck open on the hot side, so when hot water is demanded at a faucet it is instead getting cold or mostly cold water backflowing through the mixing valve.
How does a hot and cold water valve work?
The valve will have two solenoids that operate inlets for both the hot and cold water supply. The timer or electronic control, water temperature cycle selector and the water level pressure switch control the valve.
