iSpring RCC7 Installation Guide
The iSpring RCC7 installs under the kitchen sink in 2--3 hours. Required: power drill with 1-3/8" bit for faucet hole, pliers or adjustable wrench, Teflon tape. iSpring provides color-coded tubing and a step-by-step installation guide with photos. Key RCC7 installation notes: the 7-stage housing is taller than 5-stage systems -- measure your under-sink cabinet height before purchasing (need 18" minimum vertical clearance for the filter housing stack plus connections). The RCC7U tankless model eliminates the pressurized tank, reducing space requirements significantly -- recommended for under-sink cabinets with less than 12" of additional depth after the filter housing is mounted.
iSpring WGB32B Whole-Home Filter Installation
The WGB32B installs inline on the main supply line after the water meter and pressure regulator. Installation requires cutting the main supply line (shut off at the meter), installing the included 1" ports with compression fittings, and mounting the filter housing bracket on the wall. A bypass valve is recommended for filter replacement without shutting off main supply. iSpring provides detailed instructions and a dedicated US support line (1-888-600-5426). Professional plumber installation cost: $150--$300 depending on market.
