Standard Diameters & Cartridge Sizes

MDC Water stocks water filter housings in 2.5" and 4.5" diameters, each accepting standard 10" or 20" cartridges. The 2.5" diameter is the slimline standard used for under-sink, RO pre-filtration and light commercial duty — pairs with 10" or 20" sediment, carbon block or GAC cartridges. The 4.5" diameter is the Big Blue standard used for whole-house, high-flow commercial and industrial pre-treatment — pairs with 10" or 20" sediment, carbon and specialty cartridges. Cartridge length sets dirt-holding capacity and service interval; cartridge diameter sets flow rate at acceptable pressure drop.

Port Sizes & Connections

MDC Water filter housings ship with 1/2", 3/4", 1" and 1.5" BSP port options to match site plumbing. The 2.5" housings most commonly run 1/2" and 3/4" ports. The 4.5" Big Blue housings run 1" and 1.5" ports for the higher flow rates that diameter supports. Pressure-release button housings include a top-mounted relief button to depressurise the bowl before service — useful on continuous-pressure mains where a service tap can't be reliably isolated. Standard flat-top housings rely on upstream isolation valves.

Single, Double & Triple Stage Configurations

Multi-stage housing assemblies pair two or three housings on a single mounting bracket for sediment, carbon and specialty cartridge trains. A typical commercial pre-treatment train runs sediment first (5-micron polypropylene), then carbon block (5-micron CTO), with optional third-stage specialty cartridge for taste and odour or chemical removal. Multi-stage assemblies arrive pre-plumbed between bowls, ready to mount and connect. Single-bowl housings remain the right choice for simple under-sink or single-stage replacement duty; multi-stage assemblies suit RO pre-treatment, whole-house, and small commercial builds.
