Hi do you make a unequal pressure pull down kitchen spray tap. In NZ we have what we call unequal pressure which is low pressure hot water and mains pressure cold. – Mike Nixon.
Whilst most new homes are built with mains water pressure for hot and cold water, a large number of homes over 15 years of age operate with unequal water pressure. An unequal water pressure system is one which has cold water pressure (500kPa) that is much higher than hot water pressure (down as low as 35kPa). This causes mixing issues, particularly in the shower.
The easiest way for you to determine if you have unequal pressure in your home is to look at the hot water cylinder. If it says “Low Pressure” then you will most likely have unequal water pressure in your home*. The other way is to turn the mixer onto full cold and compare the water flow rate with how fast the water flows when you turn it to the full hot position. If there is a difference, then you will have unequal water pressure.
