Most homeowners operate under the assumption that their tap water is safe, especially tap water that comes from a local water treatment facility. However, while it may be safe in the sense that it has been treated to remove potentially harmful bacteria, the fact remains that traces of bacteria, minerals and other debris remain in city-treated tap water. You may not be able to taste it, but unless your home has a water treatment and purification system in place, the fact remains that it is there. If you want to provide yourself and your family with the absolute purest and safest drinking water possible with minimal effort, it may be in your best interest to install a water treatment and purification system.

What is a Water Treatment and Purification System?

Such a system can be installed in your home as a way of further treating and purifying the water that ultimately comes out of your faucets. Most purification systems are hooked up to your home's existing water tank. There are many different ways in which a treatment and purification system can improve your water quality. Many use a series of filters that remove potentially harmful contaminants and debris that may have been missed by your local water treatment plant. Furthermore, many of these systems also use a process of heating, condensing and cooling to achieve pure, clean water.

Installing a Purification System

The cost of installation for a system can vary based on where you live and the specific purification and treatment system you choose. Most homeowners can expect to spend at least $500 on such a system, though the price may be higher in some areas. In general, it is advised that homeowners hire a professional plumber or related technician to install the purification system as it may be necessary to run additional piping through the home. These purification systems are often very heavy and should be handled with care and by a professional for safety reasons.

Once a water treatment and purification system is installed, all that is left to do is to keep the filters clean and replace them as needed, which is typically around every six to nine months, depending on water usage. From there, homeowners can enjoy clean, pure water each and every time they turn on any of the home's faucets.
