\n Answer \n.
\nIt could be cross connected, I would turn on any faucet, then… go listen at your\nwashing machine and see if you hear water running through the hot and cold valve\nwhere your hoses hook on. If you do you need to replace valve on machine. If it is\na new house they may have tied the hot and cold water together. That is very very\nhard to find. You would have to call a plumber for that and then hope for the best.\nStill try the washer even on new house.

Only cold water comes out of shower hot water faucet?
I have just the opposite problem.. I'm only getting very hot water coming out of shower head..
What I've been reading is it's most likely the mixing valve/anti-scalding valve…..
As long as you are getting normal water temps and pressures from your sinks then you should either replace or repair the showers mixing valve..
The best I can explain the way the mixing valve works is it uses the pressure of both the cold and hot water to limit the amount of either hot or cold water that it will let pass through it. If the valves don't slide properly do to dirt or any thing that may build up on the valve or valve seats then the mixer valve can't do it's job properly..
Hope this helps.

Where does faucet water come from?
The water you get from your faucet can come from two places - from the water in lakes or rivers (surface water), or from water that comes from wells (groundwater). Many people… in this area who live in large cities or towns get their water for drinking from lakes and rivers. But, most people in the United States get their drinking water from groundwater. .

Why does Hot water come from a cold water faucet?
Because someone switched the lines or labeling. < 1- Someone installed the piping not bothering to read modern codes requiring water hot and cold to be 6" apart 2- C/W …supply to a tank or other heat source does not have the 27" heat trap (loop) to prevent stratification of hot water molecules entering the potable water supply 3- Failure on the part of an installer of appliances that use both hot and cold water supply to have an air gap or vacuum breaker or the very least a check valve 4- Cold water lines picking up ambient heat from the surrounding air or close contact to heating lines 5- Cross connections see #3
Why does hot water come from the cold faucet and then change to cold?
\nBecause hot water is still in the pipes from when you turned on the hot water, and when you turned on the cold faucet it had to let out the hot water first.\n.
\nThis means… you have a single-pipe sink. Double-pipe sinks have a pipe for hot and a pipe for cold and it blends them as it turns on.

Glacier bay kitchen faucet water comes out slow hot or cold how do you repair this?
I just brought a Glacier Bay pull down ceramic kitchen faucet Model 896408. After installing it, the cold water wasn't coming out of the faucet. It turned out the problem was …the coldwater supply line inside the faucet was bent & twisted. As a result, when the body of the faucet was attached, it had to be turned just a little to position it correctly, this tighted and choked the water supply line even more- which meant "no cold water." Waiting on replacement line from Glacier Bay, which, I am certain, will correct the problem.
How does hot water come to your faucets?
Through magic hot water elves. That's how hot water does come home.

Why does cold water come out of a hot faucet first?
Unless there is a recirculating pump the hot water has to come from the hot water heater. Depending on how far away it is from the faucet, it can take 15 to 30 seconds for the… hot water to get there. Since there is nothing in the pipe to keep the water hot, it cools down between uses.

If you have no hot water coming out of faucet only cold?
Sounds like your water heater is not working. Feel around the hot water heater and the lines and pipes and see if it feels warm. Also, if it's an electric HWH, find the circui…t breaker for it and see if it has tripped. If it has, turn the breaker OFF, then back on and see if that helps. If not, contact a qualified plumber to have a look at it.

Why is there no water coming out of any hot water faucet?
There should be two valves on or near the top of your water heater. One is for the inlet (cold water) into the heater the other is for the outlet (hot water) out of the heater… to your house. They must both be open ( turned to the left or counter clockwise).

Hot water barely comes out of faucet cold water works fine how do i fix?
If shut off the hot water valve then you take off your supply line from your hot water valve to your faucet and then turn your hot water valve on slowly (with of course a buck…et or something to collect the water under it) and if you can see you have water pressure and flow then most likely the problem would be in your faucet on the hot side. If you have no pressure or flow when you turn the hot valve on then it could be debris plugging your hot water pipe or your hot water service valve (angle stop, straight stop) which older galvanized pipes are known to do so. To fix the problem you would need to find out where the problem is then either fix or replace the faucet or replace the angle/straight stop or try back flushing the hot water pipe and or replace the pipe with pex or copper pipe.
