Can MIRA 722 low pressure cartridge be replace with a high pressure one?
current MIRA 722 has a gravity fed valve. But because of low pressure generally in the house, have installed a a 'whole house pump'. Do I need to replace the existing cartridge with a 'high pressure' one to avoid problem. At the moment, with the cold setting, I get warm water coming thru and sometime it gets quite hot.
