How to Install an Undersink Filter

One of the main features of a good under sink water filter is that it’s easy to install. While particular models will have their own installation requirements, the basic steps are all the same.

  • Start by gathering the tools and materials you’ll need. You need the under-sink water filter kit, along with some Teflon tape. You should also have a screwdriver, a basin wrench, and adjustable wrenches.
  • Now turn off the cold water at the shutoff water valve under the sink.
  • Disconnect the water line from the shutoff valve. This means you need to loosen the nut with the basin wrench and remove the tubing from the valve fitting.
  • Place the water filter unit on the cabinet wall near the cold water line. Mark the location through the holes in the mounting bracket. Drive screws through the marks about halfway through. Just make sure there’s enough clearance space under the filter to let you remove the canister and change the cartridges more easily.
  • Now it’s time to make the plumbing connections. If your kit has plastic tubing, think about replacing them with flexible stainless steel supply flex lines. You will have to thread the brass fittings into each side of the filter cap, with some Teflon tape for a more reliable seal. Use the adjustable wrench to tighten the fittings, though take care not to over-tighten. Thread one flex line onto the “in” fitting and another onto the one marked “out”.
  • Once assembled, hang the filter unit on the wall then tighten the mounting screws to secure the unit. Connect the flex line from the “in” fitting to the shutoff valve.
  • Connect the flex line from the “out” fitting to the threaded faucet stem. Make sure the plumbing connections are all snug, and then gradually turn the water supply back on.

Why You Should Install an Under Sink Water Filter

There are plenty of good reasons why you’d want to put in an under sink water filter in your home. The most important reason is that this filters out dangerous compounds from your tap water. These can include sediment, chlorine, heavy metals, fluoride, arsenic, nitrates, nitrites, limescale, bacteria, and other microorganisms.

In addition, these water filters tend to have activated carbon that can remove unpleasant smells and tastes from the water. This makes the water more enjoyable to drink. In fact, the water becomes better when it comes to cooking, washing, and cleaning.

Clean water doesn’t have to be expensive at all. Buying commercial water is much more expensive in the long run, and they’re certainly not cost-efficient if you’re going to use the water for washing and cleaning. Even the best under sink water filter won’t cost as much as commercial water in the long run.

It’s true that you’ll need to replace the filter cartridges every now and then, but it’s not annoyingly frequent. You only have to do this every few thousand gallons of water or so. Replacing the filters is actually easy, and you can say the same thing about installing the under sink water filters.

Putting the water filter under the sink also offers certain benefits. You don’t need it to look good, because it’s under the sink and basically it’s out of sight. You also save up space from your kitchen countertops and sinks.

Conclusion

Our list offers a wide range of prices so that even if you have a modest budget you can still enjoy safe tap water for drinking. With the more advanced systems, you get clean and tasty water with easy installation. They may cost a bit more, but they beat having to buy commercial water every day!
