Hot water

A couple of weeks ago my hot water when you turn it on there is a sound like whine, what ever knob weather bath, kitchen or shower the sound is there. Tried to evacuate the air there was no air at the hot water tank, no air in water hose to 5er. Any help appreciate, thank you

    Open and close the water heater check valve a few times. Sometimes it sticks or gets a lime build up in the valve. Working the valve will help free up and re-seat moving parts correctly.

    Water heater needs air pocket at top to control expansion of water as it heats.

    Whining sound.......

    Could be from check valve in water heater hot outlet nipple....when sticking.clogging they can whine.
    Also if on city water..the check valve in city water connection can do the same thing......but it would whine on hot & COLD. Not just hot.
    If just on HOT then WH check valve.

    There is (I believe) a check valve on the outlet of the water heater. Probably is sticking partially shut.

    Try emptying the tank and reestablish the air pocket in the top of the tank.
