More than likely it is restiction in your water heater.
Cold water is denser then hot water and weighs more so hot water will always stay on top of cold water no matter the pressure in the line or volume unless forced by flow hot water water will always be on top.
Depends where you are testing it. Possibly just a plugged aerator, or a broken seal.
Water can be hot or cold if you want
It may be in the main cold water shutoff or if you have a water pressure reducer it may be in the reducer manifold
There are several possibilities. The 2 most common would be the water heater needs replacing, or you need a repipe.
Pressure is the same whether hot or cold.
Hot or cold?
water pressure
Install on cold water line.
My guess is that the hot water heater is installed downstream from a pressure reducer to limit the maximum water pressure that the water heater is exposed to.
Hot water is lighter then cold water so it would stay up on top of cold water till both waters naturalize to the same temp. a good example is a water heater and (if its not to old) open your drain at the bottom of the water heater and if your dip tube is still good you should always get cold water out of it even if the water heater is on and your water heater pressure is on.

Most geysers erupt hot water, however there are a few cold water geysers in the world. The reason why they 'erupt' is due to pressure, it has nothing to do with water temperature.
You probably haven't re-opened the cold water inlet valve.
These are the five feelings 1. Hot 2. Cold 3. Pressure 4. Touch 5. Pain
Hot water. Hot water can also dissolve slightly more sugar than cold water can.
no not really hot water cleans better and kills germs
