The pressure-balanced shower valve compensates for changes in water pressure. It has a diaphragm or piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure.

You’re at risk from lightning during a thunderstorm even when you’re inside your home, including while showering or washing your hands. Read on to protect yourself and your family.
They also shut off rapidly in the event of a hot or cold supply failure to prevent scalding or thermal shock. It is increasingly common practice around the world to regulate the storage water temperature to above 60 °C (140 °F), and to circulate or distribute water at a temperature less than 50 °C (122 °F).
5. You can’t see what you’re doing. If you wear glasses or contact lenses, you’ll know how difficult it is to see in the shower already. If you add steam to the equation, it’s blurry for ...
Brittle failure may occur at subsonic velocity. Attempting to crimp a brittle frangible bullet into the cartridge case may break the bullet. [ 1 ] Brittle frangible bullets may break during the self-loading cycle of semi-automatic firearms ; [ 2 ] and those fired from revolvers often break as the bullet encounters the barrel forcing cone after ...
