How to Install a Reverse Osmosis Water Filter Part 1 How to Install a Reverse Osmosis Water Filter Part 1
Reverse osmosis water filters help in healthy living by providing clean and pure water free from all harmful impurities. Installing a reverse osmosis water filter is not a tedious task provided you acquire a little knowledge about the RO system. Installing the RO system on own not only saves money but also helps in understanding the functioning of the system.
Step 1 – Select an Appropriate Reverse Osmosis Water Filter
There are two types of RO membranes commonly used in most households: Thin Film Composite (TFC) and Cellulose Triacetate (CTA). TFC is more efficient and filters more contaminants than CTA. But TFC membranes are sensitive to chlorine and hence get degraded when exposed to chlorine. When using TFC membranes it is important to buy the system with carbon pre-filter especially in households who get a supply of chlorinated water. CTA membranes are chlorine resistant and hence do not get degraded by chlorinated water.
RO water filters also come with different capacities. The capacities are rated in terms of Gallons per Day (GPD) or Gallons per Hour (GPH) and denote the amount of purified water generated by the system per day or per hour. One must choose the system with capacity that meets the needs of the family. The water necessity of most households is fulfilled with the RO system of 3GPH.
Step 2 – Purchase the RO System
Make enough research while purchasing the RO water purifier. Choose the one which is well known and has a good record. Try to get the best price for the filter. One can even buy the RO water system online at a much cheaper rate.
Step 3 – Check for Pre-Installation Requirements
Most reverse osmosis water systems require a minimum water pressure of 40 psi. Households which do not have the required pressure level may need a booster pump to boost the water pressure. If the incoming water to the RO system is dusty or corroded, a whole house filter is recommended to be installed prior to the RO system. Before starting the installation make sure the place chosen to install the filter array has enough space to hold it.
Step 4 – Clean the Under Sink Area
Most RO systems are installed under the sink. Empty the sink base before beginning to work. Close the water supply valves. In case there are no valves, turn off the house water supply mains. Keep the kitchen taps open for some time to remove the remaining water and relieve the pressure. Also, unplug appliances if any, are connected to the electric outlets under the sink.
