How do I increase water pressure in my pipes?
Look on the main supply pipe near your water meter for a conical valve that has a bolt sticking out of the cone. To raise pressure, turn the bolt clockwise after loosening its locknut. Keep an eye on the gauge to make sure the pressure is within bounds, then retighten the locknut.
What is the max water pressure in a house?
80 psi
The maximum recommended water pressure for homes is 80 psi; any pressurization exceeding this amount will result in thousands of wasted gallons of water each month.
