The Pentair 161114 GRO-475BP is a 4-stage reverse osmosis system with a built-in 110V booster pump, designed for homes with low water pressure or high TDS. It reduces lead, TDS, chlorine, arsenic, and more, and connects to your cold water supply line, a dedicated drinking water faucet, and a standard electrical outlet.
Before You Begin
- Tools needed: a hand or electric drill (cordless preferred), two adjustable wrenches, slotted and Phillips screwdrivers, a file, safety glasses, drill bits (1/8", 3/16", 1/4", 3/8"), a tube cutter or utility knife, a pencil, a towel, and a bucket. If your sink doesn't have a hole for a separate faucet, add a center punch, a 3/4" hole saw or drill bit, and a safety mask.
- Safety first: Install on the cold water line only, with a nearby electrical outlet for the booster pump (110V). Your water supply should be within 40–100 psi feed pressure, 40–100°F, under 2000 ppm TDS, and under 10 gpg hardness. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection.
- Cartridges: The GRO-475BP uses FDF1-RC, GRO75-RC, F1B1-RC, and F1GC-RC cartridges, which come pre-installed in the correct sequence.
Step-by-Step Installation Guide
- Turn off the cold water supply line (install a shut-off valve first if one isn't already there), drain the line, then install the feed adapter valve onto the supply valve and connect the riser to it.
- Choose a faucet location with a flat, secure surface, drilling a 3/4" hole if needed. Mount the faucet with the drain tubing, chrome plate, and locking nut, making sure the 1/4" red drain line (with its flow restrictor still attached) reaches the RO system manifold.
- Install the drain clamp on a vertical section of the drainpipe about 6" above the trap, then connect the faucet's drain tubing to it with a straight, kink-free run to prevent reject water from leaking through the air gap.
- Mount the system vertically in a solid location under the sink, then connect the faucet to the system's outlet, the storage tank to the system, and the system to the water supply adapter using the color-coded tubing (white inlet, blue outlet, red drain).
- Plug the booster pump into a nearby outlet. Close the tank valve, turn on the cold water supply, and lift the faucet handle to lock it open, letting it drip for 30 minutes before fully opening the supply and letting it drip for 12 more hours.
- Close the faucet and open the tank valve to let it fill (about 3 hours), then open the faucet to flush the post-filter for 4–5 minutes and let the tank refill. Repeat this fill-and-flush cycle 4 times, checking for leaks throughout, before the system is ready for use.
