I'm looking to replace the section of water pipe within my house which is at mains pressure. I want to use Hep2O.
Out of curiosity I took a 10bar pressure gauge purchased from BES ages ago to measure the static pressure. I measured 9 Bar, approximately 90 metres of head!!!
Is this plausible??? Hep2O's only rated to approx 12 bar at room temperature. Could this be true? Could I have a dodgy pressure gauge? What pressure should I expect the mains water to be at?
Any ideas? I'm reluctant to use plastic at these pressures.
