Which Type of Water Treatment System Is Best?
After you have educated yourself about your water chemistry and flow rate, you can use the charts in this Guide to determine which system will work best for you. If you have any questions and want to get an expert opinion, consult a technician that has been certified by the Water Quality Association at www.wqa.org.
Select a Location for Your Water Treatment System Most automatic water treatment systems require some the following considerations: System must connect to the main line coming in, or connects to and from this incoming pipe. Often the water treatment system for the house will bypass outside garden water. Determine the height, width and floor space required for each piece of equipment. Most automatic water filter systems have some type of backwash or drain water, and need to be connected to a drain. If your home is on a septic tank, this is usually the best place to discharge the backwash waste water.
In some cases, a separate French drain (a drainage trench with gravel is used) is best, depending on local codes and soil conditions. If the backwash water contains no chemicals or salts, it can be be discharged to a garden or wooded area and used for irrigation, but local building and health codes may prevent this option. Most automatic filter systems require electrical power, although most use very little actual power. For instance, a typical iron filter will need to be plugged into a 120v outlet, but only use 0.25 to 0.5 amp or about 30 to 60 watts of power at most. Keep the water treatment equipment (and your pump and pressure tank) from being exposed to excessive heat or freezing. If your system will be housed in a small area (e.g. a shed), make sure the area is well ventilated to avoid overheating.
Likewise, protect all equipment from freezing. If you live in a seismic zone, strap your system to a wall to prevent damage from earthquakes. It is best to prevent sunlight from directly shining on the equipment to prevent the sun from warming up the filter tanks or water filters.
