RO Membrane Replacement in Raleigh, NC
The membrane does the real work in a reverse osmosis system, and it wears out quietly. Water still comes out of the faucet. It just carries more of what you were trying to remove.
A TDS meter tells the story. A healthy membrane rejects roughly 90 to 98 percent of dissolved solids. If your tap reads 400 ppm and the RO faucet reads 60, rejection has dropped to 85 percent and the membrane is due.
Bear Water Purification connects Raleigh, NC homeowners with plumbers who replace membranes in standard 1812, 2012 and 3012 housings, plus the proprietary cartridges used by brands like APEC, iSpring and Express Water. The housing O-ring gets inspected and greased with food-grade silicone, and the first two tanks get dumped to flush out the preservative.
Membrane life depends on what reaches it. Hard water scales it. Chlorine attacks thin-film composite membranes, which is why a spent carbon prefilter shortens membrane life so fast. On city water, most last two to four years.
