How to Install a Reverse Osmosis Undersink Water Filter
A reverse osmosis system is one of the best consumer-model filtration systems on the market. A reverse osmosis filter has a prefilter and a reverse osmosis filter. Water forces through the membrane of the filters and catches all large particles. Reverse osmosis systems are not hard to install but you will need to drill through your sink, which can be difficult. Does this Spark an idea?

1
Clear out the space under the sink so you have space to work.
-
2
Mark the location where you wish the water filter faucet to sit, using a permanent marker. Fit your drill with a hole drill bit. Use a high speed steel (HSS) hole drill bit so it will cut through metal and use a bit that is slightly larger than the components running underneath the faucet. Drill the hole through the metal, applying light pressure to the back of the drill.
