I had a similar issue and the two things I found that might help is number 1 check the screen in the shower head and the shower head diverting knob/lever/switch. And number 2 is that there may pin hole leaks to check for in the piping.Diverter Valve or obstructionFor a pressure loss in both shower head and faucet, check the diverter valve (usually a little pull-up knob at the end of the bath tub spout, or a valve in the wall between the tub and the shower head).
If you have a hot/cold mixing valve, the mixing valve may be defective.
Other possibilities are any obstruction such as a bent or crimped water line leading to the faucet, or algae and other unpleasant things growing in the line.
Hot water supply line may need to be increased in size for all fixtures.
Thermal expansion,. When the water heater heats up rapidly the water pressure increaces
Adjust pressure regulator valve (P.R.V.) Turn clockwise. remove water saver from shower head
PRESSURE INCREASES are normally effected by raising the height of water supply to increase the downflow. If this is not possible, increase the bore of the supply pipe from your tank.
Water pressure increases with increase of depth.
Pressure is the same whether hot or cold.
NOPE, actually it will cause more pressuyre drop do to friction losses
There are many things that one can do to increase the power of their water pressure. One way to increase the power of the water pressure is by increasing the flow of water.
Because hot water and cold water have different circuits.
increase the pressure over the water.
Hot water does exert pressure, but the main thing is that it creates steam if hot enough, and that is often used to run machines that require pressure.
Water pressure can increase, can decrease, or can remain constant, depending on the viscisitudes of the prevailing system configuration.
