Domestic Mains Water Pressure High? - 850 Kpa
I have suspected for a little while whether my mains water pressure is a little high. The cold water gushes out of our tap and our water hammer problem has not been rectified through the installation of several water hammer arrestors and ensuring that the pipes are properly cliped to joists.
We live at the bottom of a gentle hill and so I started thinking that this could be causing higher than avergae water pressure. I decided to grab a pressure gauge today to test it. Turns out our water pressure is 850 Kpa (8.5 bar).
I assume this is a little high. I have read that the code states that pressure should be limited to 500Kpa.
Should I get a pressure limiting valve installed near the mains? Is 850 Kpa excessive?
