Review on 💧 Certified iSpring RCC7 5-Stage High Capacity Under Sink Reverse Osmosis Drinking Filtration System with 75 GPD, Brushed Nickel Faucet by Lisa Gunterman

The old Sears two-stage activated carbon water filter wasn't good enough. This made the water tastier, but didn't remove the unwanted dissolved solids. We bought bottled water anyway, it tastes better. It's time to make the switch to a reverse osmosis water filtration system!► WARNING. This product review was originally posted on April 17, 2017 but disappeared so I resubmitted it!

Cons: - I needed longer plastic tubing for our setup. The intended 10-foot distances were too short. ◄ iSpring supplies longer hoses - From the installation guide: The water pressure in the block is at least 40psi. If it is below 40psi you will need to add a booster pump. If the water pressure is over 80psi, you will need to install a pressure regulator. Our water pressure was over 80psi, which added to the cost of the system. We didn't care that the polished nickel finish faucet that came with it didn't match our fixtures. ◄ iSpring will work with you to provide a faucet suitable for your installation - water is wasted to create purified water. The ratio of brine waste water to purified reverse osmosis water is 2:1 to 3:1. That means it takes 2 to 3 gallons of water to make 1 gallon of purified water. ◄ For those who worry about wasting water. Also see my comments on wastewater treatment below - Advertisement - Origin China. ◄ for those who prefer to buy products made in the USA. Our Installation: ▪ Our previous Sears filtration system was installed in a garage, so this was the logical place to install this filtration system upgrade. It is located next to the water heater ► the cold water source and next to the washing machine ► the laying point for the brine waste water pipe. ▪ In our setup, the treated water storage tank was placed on its side to fit the storage rack ▪ I decided to purchase an inexpensive plastic pipe cutter, a PneumaticPlus TC nylon, PVC, polyurethane plastic pipe and hose cutter. Not required, but it cuts pipe perfectly and speeds up installation. Here is the Revain link: PneumaticPlus TC Nylon PVC PU cutter for plastic tubing and tubing up to 3/4" OD (Dripline Knife) (1) ▪ I also bought the TSPITOOL Quick Connect Tool, which didn't either is required but makes it much easier to disconnect the plug Also installs the lock in preparation for the locking clips 4" or 3/8" fittings (TSPITOOL) ▪ Throwing away the old Sears two stage filter housing was a waste, so I decided to leave it with the other filters 10 micron, both sediment filters The outlet of this 2 stage filter is connected to iSpring RO, a 1 stage reverse osmosis sediment filter, 5 micron To monitor the water pressure in the system I have I installed a water pressure gauge. VERY handy as the reading goes down as purified water is produced and goes up. turns off when the purified water tank is full. After a few cycles you have normal me worth. ▪ After the water filtration system worked for a while, I began to wonder when the brine flows - waste water. I was concerned about the failure of the ASOV - the failure of the automatic shut-off valve that could ensure a constant flow of sewage. For a visual indication of the flow rate of brine - sewage, I installed a Rotameter LZM-15 flow meter. See my attached photos. This flow meter won't work as is, but with a simple modification (see my flow meter review for details) it will give a visual indication of when brine is flowing. Here is the Revain link: Uxcell a11120300ux0019 1 female thread /2 inch 0.2-2.0 GPM 1-7 l/min Water and Liquid Flow Meter LZM-15 Rotameter container to allow this water to be recycled in perfect quality. In summer, reverse osmosis brine - waste water is used to irrigate our high vegetable garden and flower beds, in winter we use reverse osmosis brine - waste water in the washing machine cycle. there is no need to buy distilled or bottled drinking water. ▪ The flow rate of our kitchen faucet, located approximately 15 feet from the filter system, is 0.5 gallons (1/2 gallon) per minute. ▪ System startup, first Total Dissolved Solids (TDS) reading: Press - city water = 100 to 98 ppm ► RO - reverse osmosis water = 3 to 4 ppm ▪ You will need to replace the filtration system filters in about a year. A reverse osmosis membrane can last 2 to 3 years (depending on the quality of your water source), so it's a good idea to start by purchasing replacement filters. They're cheap to find if you don't need them right away and can take a closer look. I have enough filters in stock for 2+ years. :)► Update - June 7, 2017 ▪ Reverse osmosis system works great! Since we installed this water filtration system, we no longer need to buy water. ▪ In my last test, TDS is Total Dissolved Solids. Tap water = 110 ppm and reverse osmosis water = 9 ppm. ▪ City water. The TDS of tap water shown above is 110 ppm. Reverse osmosis brine - waste water TDS is approx. 20 ppm higher. ▪ It's summer, so we're recycling reverse osmosis brine - waste water from the garden and to water the flower beds. ▪ We have to accept the amount of brine - wastewater was a bit shocking when we started saving it, but that's the nature of RO - reverse osmosis water filtration systems. 2:1 to 3:1. that is, the amount of brine - effluent > to > purified water. It's not so bad if you can recycle waste water! ▪ The city we live in calculates our sewer bills based on the amount of water we use, so it makes sense to recycle reverse osmosis brine - waste water! ► Update – October 24th. , 2019 ▪ System works great, still on original filter! The TSD has increased slightly and the brine and waste water flow rates are 3:1 or more, so replacing the system filter is on our to-do list! ▪ I've added a new photo of our six 5 gallon black pails that we use for brine wastewater reuse.
