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 is there no hot water in my upstairs bathroom?
If you find one of these, you’ve probably found the culprit. You should be able to adjust it with a flat-head screwdriver. If your house is old, you may have corroded water pipes, and they are especially likely to affect the water pressure in an upstairs bathroom.
What to do if you have no hot water in your bathroom?
All other possibilities aside, if a hot-water deficiency in a bathroom is accompanied by a loss of water pressure, that’s a symptom of a leak. Test the water pressure in the bathroom faucets with a pressure meter; it should be about the same as the pressure at the water heater. Call your new plumber friend if it’s significantly lower.
How long does it take to get hot water from kitchen sink?
If you are at a kitchen sink it will take about 16 seconds to get the hot water, assuming the flow rate of your fixture is 2.2 gallons per minute, if the cold pipe wasn’t sucking any heat out of the water. Normally bathroom sink fixtures are restricted to 1 gallon per minute or less, and many shower heads are 1 gallon per minute.
