Can anyone here tell me why the pressure limiting valve on caravans is set to 350kpa, while the same valve for houses is set to 500kpa.
Bearing in mind the relief valve of the hot water unit is set for 850kpa (124psi), so water pressure within the water circuit of a van on a hot day could reach 849kpa, nearly three times the setting for the pressure limiting valve.
