The pressure of the water is defined by the weight of the water pushing down as a result of gravity. If you're hot water tank is full then the pressure will be high and the hot water will gush out, if there is little hot water then the pressure will be less.
Also, if you live in a hard water area then the shower head might be clogged with limescale. Try cleaning your shower head if it is covered with a thin scale.
WOW I never heard such nonsense1- If the shower head was clogged with scale then BOTH hot and cold would diminish2- If the hot water tank was not full of water and had air in it the pressure would actually INCREASE as the water is heated as AIR can be compressed and water very slightly increases
Ever take a balloon fill it with air and pop it?
Now try it with water it plops open
The low water condition could be a washer blocking the orifice by the valve seat
Your only condition is one fixture so the other persons advice is totally wrong
They actually don't care about you.The hot water heats the air in the shower. The hot air has lower pressure and rises to the ceiling, escaping through the opening between the shower curtain and the ceiling. This process forces the relatively cold air in the rest of the room to sneak in under the curtain, thus forcing the curtain inward and (annoyingly) onto you.
Air pressure changes when the hot water generates warmer air, thus like the weather, wind (or in this case a small draft upwards) is generated. Air pressure and current causes the shower curtain to move as cooler air is sucked under and around the curtain.
Your hot water heater is not large enough.
when the water pressure is low in the shower
well because if you shower with hot or warm water then ofcorse you get out and your bathroom was not cold.It just feels like it's winter when you get out.You put on the hot water and when you get out you shiver since the bathroom is not as hot as the hot water that you put on.thats why.
you have trash in your line take the shower head off and remove trash or possibly in water valve at shower
Maybe pressure balancer going bad or you don't have a pressure balanced valve
Hot water is spraying out into the atmosphere at high pressure. This causes condensation.
Well, if you take a shower with hot water, it should get worse, since a hotter temperature increases blood pressure....
This is probably a pressure imbalance problem or you have air in the lines. see the related video link provided.
A stuck or worn balancing spool in a pressure balanced valve.
My first thought is a leaky hot water line.
Run a new cold supply line from the source. This will drain less pressure from the the cold shower line.
The piping has to be the exact same length for each shower head from the tee where the cold and hot water feeds from the top of the diverter faucet.
Open up the actual shower head and remove the factory fitted restrictor.
Because hot water can raise your blood pressure rapidly. Otherwise you'd be refreshed and energetic.
Your water pressure is low. Consequently, when cold water is diverted to another application such as a toilet or a sink, the amount of cold water available at the shower mixing valve decreases as the low pressure is unable to keep up with the shower's demand. This causes a hotter mixture at the shower head. The solution is to either improve the cold water supply to the shower or to replace the shower control valve with a temperature compensating type. Pressure balancing is the cheapest and simply changes the shower temperature according to the pressure in the cold and hot water lines. When the toilet or sink is used, reduced pressure to the shower valve is detected and the valve reduces the hot water pressure, thereby maintaining the temperature. The more sophisticated approach is a thermostatic shower control valve. These are significantly more expensive, but will not reduce the pressure at the shower head (a drawback of the pressure balancing valve). The thermostatic valve would be required when one shower control valve is operating several shower heads. Moen, Kohler and Delta all make both types of control valves. They can be readily obtained from a local plumbing supply house.
