How To Pick the Best Under Sink RO System

When Picking a RO System for under your kitchen sink there are a few things we suggest you take a look at and consider. You need to consider the size of the filter and how often it is required to be changed.

It sounds almost like a super-hero name or something made vague intentionally so that business can take advantage of you, but when you break it down, reverse osmosis isn’t either. It’s a water filtration and purification system, often installed under the sink. As much as water companies try to provide clean water, there are some things that just keep getting through, and a lot of them aren’t EPA regulated, so an additional step is required. Reverse osmosis systems produce great tasting water, require minimal upkeep, are reasonably priced, fully automated, safe, and work like a dream. They can be used in a variety of environments, from residential to military to disaster relief and hospitals to commercial environments like agriculture, hotels, and the food and beverage industry. If you do enough of the right research, you can even install them yourself from a reputable company like Whole House Water Filtration Systems.

What is an Under Sink RO System?

To do any of there are a few things you need to know. First and most importantly is how does it work? Basically, reverse osmosis removes solids from solutions, in this case, water. In a household, for example, this is accomplished by pushing tap water through a selective membrane using water pressure. Some of the impurities removed from the water are lead, fluoride, chlorine, chloramine, nitrates, pesticides, sulfates, detergents, and salts, among others. This is often a four or five step process that has been working beautifully since 1977.

Under Sink System Installation

Installing your own under sink ro system does not have to be the end of the world. Installing under sink systems should be done carefully but can be handled by someone with less the professional plumbing skills.

The worst part about installing something yourself is trying to figure out what all the parts are called and where they go. This would be better suited with diagrams, but words will have to do. I’ll start with a list and then break down their functions and order.

The basic components are the cold-water line valve, pre-filter or filters, the reverse osmosis membrane, post filter or filters, automatic shuttle valve, check valve, flow restrictor, storage tank, faucet, and drain line. The cold-water line valve is that valve that attaches to the cold water supply line, which is where the water starts. Included is a tube that attaches to the inlet side of the pre-filter. The pre-filter is the first filter that the water enters. There is often more than one, most commonly sediment and carbon filters. Carbon filters specifically are used to remove chlorine, which can damage the membranes. In general, pre-filters are used to protect the membranes by removing sediment, sand silt, and dirt. The Membrane is the big deal component. It’s used to remove a wide variety of contaminants both for health reasons and to improve taste. After passing through the membrane, the water goes into the storage tank. This tank is pressurized, can hold between two and four gallons of water, and is 12 by 15 inches. In between the storage tank and the faucet, water goes through the post filter. This is called the “polishing” filter and is usually a carbon filter. A reverse osmosis unit often has its own faucet. Plumbing regulations may dictate what kind you use, but no-air gap faucets are more commonly used than air-gap faucets. The drain line runs from the outlet end of the membrane to the drain and is used to dispose of the wastewater that contains all the nasty stuff like contaminants and impurities that have been filtered out.

The automatic shut off valve is located between the pre-filter in the membrane. Its purpose is to conserve water. It closes when the storage tank is full, preventing any more water from entering the membrane and blocking flow to the drain. The shut-off valve will open when the pressure in the tank drops, which happens when water is drawn from the faucet. The check valve is located on the outlet end, right side, of the membrane. The purpose of the check valve is to prevent water from going backward from the storage tank to the membrane, which could rupture the membrane. The flow restrictor is between the membrane and the drain, most often in the drain line tubing. The flow restrictor maintains the flow rate and pressure inside the membrane. This can be done through a variety of controls and varies depending on the water capacity of the membrane, but without the flow restrictor, most of the water would flow down the drain instead of out of the faucet. The flow restrictor combats this path of least resistance.

There are some factors that affect how a Reverse Osmosis system functions. These include water pressure, water temperature, type and number of solids dissolved in the water, and the quality of the parts used in the system. If water pressure is too low, the system won’t work as well. Cold water takes longer to filter than warm water. The more solids that are present, the harder the system has to work, and the more it might miss, statistically speaking. The biggest difference between reverse osmosis systems is the quality of the parts. You want the most top-notch parts you can get your hands on, and that’s why it’s important to buy them from a reputable site like Whole House Water Filtration Systems.

Speaking of how Reverse Osmosis systems differ, there are a couple of other ways. I’ve already mentioned the biggest one, quality of parts, but they also differ in the number of filters used, and the amount of water processed. Some systems have four stages and some have five. The amount of water a system can process is measured in gallons per day.

How Long Will My RO System Last?

Upkeep is minimal with Reverse Osmosis systems, but it is there. Depending on what type of filter it is, it could be six months to two years before you need to replace it. Pre-filters should be changed every six-12 months. Post filters should be changed once a year. Membranes can last two to three years. Look in the manual if you aren’t sure. Regardless, systems should be regularly sanitized and cleaned once a year. Properly maintained, a Reverse Osmosis system can last 10-15 years.
