How important is capping water pressure at 80 psi on large luxury homes? We build/sell them and some of the remodeled homes (do both new and remodel) have around 90 psi and the inspectors make us reduce to 80 psi...living in a couple of these homes, the pressure is already a nuisance when the sprinklers are on or multiple usages at same time. The pressure on the showers is adequate for some of the fixtures but low pressure items like a rain showerhead are almost unusable, even at 90 psi. quality fixtures and pex plumbing lines should be able to handle 90 psi, no ?
