At 33 Buckets, we focus on developing clean water solutions for underserved communities around the globe (view our projects here).  Our knowledge in filtration is transferable to domicile filtration systems so nosotros idea with this mail service that we would share information nigh at habitation h2o filtration systems, especially for those that currently drink bottled water.

Consumption of bottled water is increasing every year. Annual consumption of United states of america residents in 2022 was 11.7 million gallons, and has increased more than 47% since 2005 [ane]. Bottled water consumption has continued to increase today effectually the earth, despite at home filtration being easier than ever. Fridge filters, Brita filters , and various sink attachments provide many options to cull from; however, many people still choose bottled water considering these filters might not accost the gustatory modality of their tap h2o.

In this article, we share tips on how you can install your own RO system under your kitchen sink that volition remove many common taste issues, so you can save money and the planet. If you only turn to bottled h2o for convenience when you're out of the house, consider purchasing one of our 33 Buckets reusable water bottles .

Installing a Reverse Osmosis (RO) Arrangement is non as difficult every bit you lot might think!

Water is a central need for your health and information technology is important to eat information technology in large quantities every day. It has been estimated that, on average, people should drink 12.5 cups or 3.2 liters per day [2]. Proceed in mind that you may need even more than depending on your level of do, the weather, and/or your health condition.

That is a lot of water to swallow on a daily basis! Although your tap water is probable treated, and is safety to consume, many practice not enjoy the taste or smell. This is probable from the hardness caused by dissolved solids and heavy metals, or the chemical taste from residual chlorine used to disinfect tap water. The verbal bug vary depending on where y'all live and your h2o source. Alternatively, Brita filters can ameliorate the gustation of water through the removal of chlorine, simply it does lilliputian for heavy metals and dissolved solids. They can be a hassle to use, every bit you lot have to refill them daily to meet your water consumption needs.

Bottled H2o Considerations

Many people plow to bottled water for the taste and the perception that tap water is unsafe. But unfortunately bottled water is highly unsustainable, more than expensive, and may non actually be safer to drink. Although bottled waters may exist perceived as a "safer" option to tap h2o, their source and chemical characteristics vary widely, and are not necessarily better or different than your tap water [three]. Bottled water has been plant to be over 30 times more expensive than tap water [5], and despite the marketing that might brand yous think your h2o comes from a far away spring -- 25 to 40% of bottled water is filled direct from municipal systems [half-dozen]!  Additionally, it has been estimated that merely 14% of single-use bottles get recycled, and the 86% of bottles sent to landfills take over one,000 years to biodegrade [6].

Introducing: RO Filtration Systems

If you are currently a bottled water consumer and take tried other alternatives without success, an RO (opposite osmosis) system might be a great solution. They are relatively easy to install (~1-2 hours), and remove nigh everything from the water including heavy metals and dissolved solids. Installing your RO system is considerably more sustainable, user-friendly, and effective than using bottled h2o. If these reasons are not convincing plenty, installing an RO arrangement can too salvage you money if you are currently purchasing bottled water.

RO filtration is not a method we unremarkably utilize in our projects away. It is more than expensive than other water filtration options--however, it is ane of the most constructive means to filter water. Maybe even too effective -- go along in listen that since RO systems remove just well-nigh everything from your water, it also removes healthy minerals your torso needs. We recommend adding trace minerals so that you can still feel the health benefits of having these minerals in your h2o. If you exercise not add trace minerals, you may want to consider taking a dietary supplement to ensure yous are all the same getting acceptable Magnesium and Calcium.

Buying an RO System

There are several unlike options bachelor when it comes to purchasing an RO system for your domicile. In this article, we volition be focusing on filters you tin can identify under your kitchen sink. We like the APEC RO Arrangement at $199 because it has 5 stages of filtration, is cheaper to maintain than competitors, and has a high output (50 GPD). The RO system comes with 5 filters, fittings, and a faucet.

It is recommended y'all replace the pre-filters (two sediment filters and i carbon block) every half dozen months, which will cost you lot about $27. The RO filter and postal service-carbon filter only need to exist replaced every 2-four years depending on your usage and h2o quality. Yous tin can purchase a complete set of replacement filters for near $67. Yous should conservatively wait to spend $54 most years to maintain your arrangement so $94 the year you supplant all of the filters. (The average American spends 100 dollars per year on bottled water [seven], and this price only goes up if you have a family).

RO filtration is one of the most constructive methods of removing contaminants from water--it removes 95-99% of water contaminants including chlorine, sodium, arsenic, atomic number 82, nitrates, other heavy metals.

Phase 1 (sediment filter)  removes grit, large particles, and rust.

Stage 2 and three (carbon block filters) remove chlorine, chemicals, and odor.

Stage three (RO membrane) removes all particles down to 0.0001 microns (this is really tiny---for some perspective a cross department of man hair is fifty microns). This includes chemicals, salts, heavy metals, and viruses. The water is and so stored in a pressurized storage tank, and must laissez passer through the concluding carbon post-filter earlier it reaches your faucet.

Please note that although RO Systems are clearly very effective, they too waste a lot of water. For every gallon of filtered RO water, well-nigh 4 gallons of water are wasted. RO Systems might non be as suitable if y'all live in an area with water scarcity concerns.

Installing an RO filter

Installing an RO organization is relatively simple, intuitive projection, but at that place are a few things to consider. You will need to have a hole in your countertop for the faucet. The simplest, virtually straightforward method is to just remove your soap dispenser and use this hole every bit seen in Figure two. An culling is to drill a hole through your granite. There are online resources available that guide you through this procedure and you will need a drill bit.

You volition likewise demand a few tools on hand, including:

  • A drill

  • 1/four" drill bit (for the waste line),

  • 5/eight", 9/16" open up-finish wrench, or adaptable wrench

  • Phillips screwdriver

  • Teflon tape

You lot will need to connect your RO organization to your h2o line. This involves using a T-plumbing equipment to dissever your cold water supply line nether your sink as seen in Figure 3. This is a pretty straightforward process that the RO system instructions will guide you through.

You lot will also demand to connect to connect your RO system to a drain line so the contaminants and unused water have a place to drain. This involves drilling a ¼" hole in your drain line then installing a clamp as seen in Figure 4.

You will likewise need to connect to connect your RO system to a drain line and then the contaminants and unused water take a place to drain. This involves drilling a ¼" hole in your drain line and and so installing a clamp as seen in Figure 4.

Subsequently making all of the connections, your RO system should look similar the sample in Figure 6. Keep in mind that you lot will need ample room under your sink.

Overall, installing an RO arrangement is not as difficult as you might call back and volition let you to have refreshing filtered water at your disposal. Requite it a try!
