Scale never gets a vote.\u003c\/p\u003e\u003cp\u003eEspresso water is designed, not filtered by luck. Our systems pair carbon and membrane stages with mineral dosing, so hardness and alkalinity land where boilers live long and cups taste sweet — typically 40 to 80 ppm with buffered alkalinity. Heads are brass, housings are pressure-rated far beyond mains, and every cartridge change is a hand-turn, not a plumber's visit.\u003c\/p\u003e\u003ch3\u003eDesign \u0026amp; Craft\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCartridge schedules printed to your daily draw\u003c\/li\u003e\n\u003cli\u003eHardness and alkalinity landed where boilers live long and cups taste sweet\u003c\/li\u003e\n\u003cli\u003eBrass heads with metered bypass and hand-tight cartridge changes\u003c\/li\u003e\n\u003cli\u003ePressure-rated housings far beyond mains; leak trays and shutoffs standard\u003c\/li\u003e\n\u003cli\u003ePush-fit connections a careful owner installs in an afternoon\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFormat\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDuplex heads, no-interrupt change\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBypass\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMetered, settable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStages\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eScale, chlorine, taste\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGauges\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSupply + post-filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePush-fit, hand-tight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e≈ 9.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 years; cartridges scheduled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eCare\u003c\/h3\u003e\u003cp\u003eChange cartridges by litres, not months — the meter on the head counts for you.
