Point of Entry vs Point of Use Water Treatment

Treated water is a vital part of our lives that can be often overlooked. Without treating the water in our homes, most of our daily routines would be a lot more difficult. Simple things we take for granted everyday like pouring a glass of water from the faucet, brushing our teeth, and even taking a shower would all be much less enjoyable if the water coming through our fixtures was full of impurities and contaminants.

Luckily, we have solutions to these water problems. Point of Entry (POE) and Point of Use (POU) water treatment systems are the most common ways for water to be treated for your home. Although a fairly simple concept, it is helpful to understand the differences and similarities between the two and how each one can help you reach your end goal of better water.

Differences Between POE and POU Water Treatment Systems

POE (Point of Entry) systems are essentially anything installed to the main water line of a home. Commonly referred to as “Whole House Systems” these types of equipment are the starting point for all the water that eventually makes its way into your faucet, dishwasher, washer, shower, and other fixtures in your home.

Water softeners, conditioners, filtration units, and acid neutralizers are a few of the most common POE systems out there today. These POE systems are high capacity which means they can treat thousands of gallons of water a day. These units are typically larger in size than the POU (Point of Use) systems and, because of that, they require less maintenance and filter replacements than a smaller POU system.

POU systems, on the other hand, are located at the end “point” of your water line. They will filter your water right before you need to use it. A few examples of this would be a filter underneath the sink in your kitchen, or one built into your refrigerator that handles the water coming out of the dispenser in the door. POU systems are best used for smaller quantities of water and on average will last anywhere from 6 months to 1 year before a new filter needs to be swapped out. The most common type of POU system used for water treatment is a reverse osmosis (RO) system. These purification systems help reduce all kinds of particles and impurities in your water like chlorine, fluoride, metals, and other contaminants. The end result is purer and better tasting water.

What’s the Best Solution For Me? POE Or POU?

Finding the right solution to your home’s unique water situation is complicated. The most complete answer is to incorporate each type of system into your home depending on your home’s water conditions and what quality of water you want to achieve. You may be wondering; how do I go about doing that? The first thing you should do is contact your local WaterCare water treatment expert. They will come out to your home and conduct a free water test. Once the water test is complete, you will have a clear understanding of which combination of equipment will be the best solution for your unique water problem. For example: Say you had a water test done for your home that’s on city water. Your water results may come back and indicate that you have hard water, specifically high levels of calcium and magnesium. You may also notice that your city water smells and tastes like chlorine from the treatment process municipalities do before they distribute the water to their residents. The water treatment professional could install a CareSoft Elite RC® water softener to eliminate both of these issues for you. You now have soft water that has the chlorine filtered out moving through the house, but you may also have additional concerns.

Perhaps you are worried about lead contamination either from the city’s infrastructure or if you live in an older house, there may have been lead pipes used when it was built. A water softener will not be able to help with lead removal. Your authorized WaterCare dealer would recommend installing a POU reverse osmosis filter to your kitchen faucet that is certified to filter out lead. This way you also have purified drinking water right from the tap that you can trust. As you can see, the right combination of POE and POU systems can help you achieve your water quality goals.

What are You Looking to Achieve with Your Home’s Water?

It is important to first consider what it is you want your water to do for your home. Are you looking for soft water? Do you want to have purified RO drinking water? Does your water have a smelly odor? Is the iron in your water staining your bathroom fixtures? Whatever the problem is, call your local WaterCare dealer or visit www.watercare.com/find-a-dealer to schedule a free water test today. Your WaterCare dealer will put you on your way to achieving your ultimate water quality goals.
