What is the water pressure in a house?
Water pressure is measured in psi, or pounds per square inch, and represents the force at which water enters your home from the water main. Normal psi for a home pipe system is between 30 and 80 psi.
What happens if you have too much or too little water pressure?
Having too much pressure can cause damage to pipes and appliances, while having not enough water pressure can result in poor performance of sprinklers and showers. Understanding more about the normal pressure ranges and the causes of pressure problems will help you problem solve issues with pressure.
What should the water pressure be in my house?
However, anything below 40 psi will likely lead to poor performance of devices that use water. Anything higher than 80 psi could lead to damage, such as blown sprinkler heads or ruptured pipes.
