To Filter or Not To Filter?

One question we get asked a lot is – do I need to filter my tap water? And unfortunately, the answer is always – it depends. There are a number of different reasons why you may or may not want to filter your tap water, as well as a variety of different ways to do so.

The main reason people tend to ask this question is because they’ve heard something in the news or online or from a friend or wherever that says drinking regular old tap water is unsafe or bad for your health. While we here at PlumbingSupply.com® are not doctors, we do know that all drinking water supplied by a municipality in the United States is regulated by the EPA for safety and is considered healthful and safe for the majority of people. That doesn’t mean, however, that there aren’t reasons to filter your water – including taste or odor, sand/sediment, and individual lifestyle or health concerns.

The EPA regulates the amount of certain minerals, chemicals, bacteria, and other microorganisms that can be present in our drinking water to ensure not only that harmful things are kept in check, but also to help provide optimal levels of healthful things like magnesium and fluoride. These levels are frequently tested and your water municipality must notify you within 24 hours if there is some kind of problem and your water is either unsafe to drink or may cause a health issue. It is important to note, though, that certain chemicals and compounds that may be present in drinking water are not regulated or tested for a variety of reasons – and we are still uncertain of the long-term effects things like leftover pharmaceuticals in our drinking water may have on our health.

Additionally, it is important to understand that water quality is very complex and can vary from town to town, from neighborhood to neighborhood, and even from house to house on the same street depending on several different factors, including the initial source quality, treatment methods, and municipal and home plumbing systems. For example, your home might have a different type of plumbing system or an older plumbing system than your neighbor’s, which can sometimes affect the taste, odor, or other qualities of the water.

The very first step in deciding whether you should filter your water or not is to know the quality of your water source. Those who receive municipal water can request a water quality report from their water company. Many municipalities offer an online download so you can look it up any time, or you can ask for a paper copy to be mailed to you. The report should tell you things like the methods used to treat the water, the general hardness of the water, and overall levels of certain chemicals, minerals, and microorganisms. If you’re on a well, we recommend having your water tested by a professional. Your local city authorities or municipal water company will usually have a list of water quality professionals you can contact.

countertop-filter If the overall quality of your water is acceptable, but you simply don’t like the taste or odor, we recommend installing a countertop carbon filter for drinking. Carbon filters will usually clear up taste and odor issues for a relatively low cost. Countertop models attach easily to the existing water supply under your sink and can be moved with you – a bonus if you rent. If you’re worried about chlorine or lead, most carbon filters will also remove these elements. We also offer filtered shower heads that can help remove chlorine and may be helpful to people who are concerned about the health effects of breathing in chlorine.

If you’re concerned about fluoride, we recommend first determining how much fluoride is in your drinking water and how it got there, and then discussing your personal fluoride needs with your dentist. Fluoride naturally occurs in many drinking water sources, and is beneficial to our dental health. If it is present in appropriate amounts, your local municipality may not add fluoride to the water or may even remove some of the naturally present fluoride if levels are too high. Note that carbon filters won’t remove fluoride and you may need a more involved filtering system, like a reverse osmosis system if you want to get rid of it.

lakos-sediment-filter Sometimes your water can pick up sediment somewhere between the water treatment plant and your faucet, but the biological quality of the water is still good. In these cases, you may just need a simple sand separator to solve the problem.

If the overall quality of your city tap water isn’t what you would like it to be, you have well water, or you have certain medical conditions, you may need to filter your water. However, before you choose a filtration system, we recommend consulting a professional to help you figure out what should be removed and what should be kept.

Now it’s your turn – do you filter your tap water? Why or why not?

Residential Water Filtration Guide

If you’ve looked into filtering or otherwise treating your water, you’ve probably noticed that there are many options and a lot of information out there. We understand it’s not always easy to understand, so let’s see if we can simplify some of it.

People typically ask us about three methods of residential water treatment: reverse osmosis, filtration, and Ultraviolet (UV) Light. Each method has its pros and cons, and each one can be ideal for different situations. Sometimes a combination of methods is actually the best solution.

reverse osmosis systems from PlumbingSupply.com

Reverse Osmosis (RO): Reverse Osmosis is a process in which water is forced by pressure through a semi-permeable membrane. This is great for removing several contaminants from the water, desalinating, as well as providing mineral and pathogen free water. RO membranes are affected by chlorine, and nearly always need a carbon pre-filter to help protect the membrane.  Reverse Osmosis units are also known for using a lot of water in the production; for example a very basic system may use 3-6 gallons (depending on your water conditions) of water in order to produce one gallon of clean RO water. Since water coming out of an RO system is virtually mineral-free, it is considered “aggressive” and will leech minerals out of surrounding materials, such as pipes, so be sure you use an RO system with faucets and plumbing systems that are designed to handle this. For these reasons, RO systems are usually used just for drinking water rather than for a whole house system. For more information on RO systems, click here.

Filtration: Probably the easiest and least expensive choice, simple filtration can solve many common water issues. Depending on your needs, filters can be used in conjunction with RO and/or UV systems or stand alone. Filters are given a micron rating that represents the size of the openings between pieces of filter media and the size of particles that filter will remove. Quite simply, the smaller the micron rating, the smaller the openings that allow water to pass through. Larger micron ratings are great for filtering sand and other large particles, while very small micron ratings can also filter cysts and fine silt. Naturally, the smaller the micron rating, the more it will catch. Filtration systems that are designed to catch several sizes of particles will often have a series of filters of different micron ratings to keep any one filter from having to be changed too often, but still filter the water effectively.

With the choice of filter type, you also have the choice of installation method. For drinking water only, a countertop or under counter unit is typically considered to be the most convenient to install, operate and maintain. Depending on your particular water conditions and if you are able to make modifications to your home, you may consider a whole house filter to ensure that all the water used in your home is safe from contaminants.

Ultraviolet (UV): UV light systems work by exposing contaminated water to radiation from UV light which effectively inactivates bacteria, viruses and other organic contaminants. The UV light actually penetrates the cell walls of the organism and disrupts the cell’s genetic material, making the cell unable to reproduce, which renders it harmless, but does not remove the contaminant. The effects of the UV light on contaminated water are not residual; there are no lingering disinfectants in the water to continue disinfection after exposure to the UV light. This is both a positive and negative aspect of this form of disinfectant. A UV system is often used in conjunction with other treatment methods and should always be used at the closest point possible to the end user, such as under the counter for a drinking water faucet.

In order to form a more comprehensive list of options, pros or cons specific to your needs, you will need to check with a local water quality professional for the best advice in treating your water. Ultimately, the best method for your home depends on your water quality, and what you’re trying to get out of the water you have. If you only want to make your city water taste better, your ideal filtration method will be different from someone who needs their sandy well water to stop fouling the water heater.
