iSpring RCC7P-AK Under Sink 6-Stage Reverse Osmosis Drinking Filtration System with Alkaline Remineralization, and Pump
About this item
- Reverse Osmosis requires high water pressure to force the impurities out of the water. RCC7P-AK’s extremely durable electric booster pump ensures high efficiency, reliable, and consistent performance regardless of pressure variations; delivering the highest performance for an RO system with less waste water.
- High Capacity Reverse Osmosis water filtration for safer, healthier water. This under sink mounted water filter and water softener removes up to 99% of over 1, 000 contaminants, including PFAS, lead (removes up to 98% of lead), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more.
- The RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below. The iSpring RCC7P-AK includes an additional sixth stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives the water a more natural taste than regular 5 stage RO water.
- With Premium quality components ensure highest reliability and low maintenance for many years to come. Clear see-through 1st stage housing makes filter inspection a snap. Pump power adapter: 100-240V 50/60Hz

I purchased this RO system and love it. One problem with this system though is that the water delivery rate is pretty pathetic even with a booster pump. That is in large part due to the small tubing that this system utilizes, which really chokes down the flow rate (1/4 inch tubing). I modified it to provide much better water flow/pressure. I purchased the iSpring T20M, the 20 gallon water storage tank, which was a bit pricey, but provides great volume. Next, I used 1/2 inch PEX pipe to plumb from the 20 gallon tank to my kitchen faucet. I inserted a "Tee" into this PEX line from the outlet of the Alkaline Filter to feed/pressurize the 20 gallon tank. I removed the cold water supply from the kitchen faucet, and replaced it with the PEX connection to the 20 gallon tank. That way, when I turn on cold water on my kitchen faucet, I have RO water. The hot water at the kitchen faucet is direct from the well (unfiltered), but I don't drink hot water. Also, with the 1/2 inch PEX, there is no real flow restriction, so the pressure at the tank is the pressure at my faucet, which is pretty good. I also supplied my refrigerator ice maker from this system, and the ice cubes are nice.
Last, I put in a TDS monitor - my home is on a well, with TDS in the mid 500's, which is not the healthiest water to drink. The TDS measured on the outlet of the RO system is in the upper 20's to low 30's.
In the future I'm thinking of putting in a small pump in the line with the "Tee" to increase the pressure supplied to the 20 gallon tank. That would give me great pressure at the faucet, but the pressure is pretty good now. I'm also thinking of putting in a small hot water tank on this system to feed the dishwasher. Feeding the dishwasher with RO water would make it last forever.
Overall, I really like the RO water this system provides, very healthy, and tastes great!
