Backwashing Frequently Asked Questions
Lots of folks have asked questions about the backwashing head on the whole house system. Here are the five most commonly asked questions and the answers.
What is backwashing?
Backwashing is the process of forcing water through the filter in the wrong direction to unclog the dirt and sediment which has blocked the filter. Backwashing is a common practice for certain whole house and commercial units which are treating large volumes of water for utility purposes but it is not a recognized practice for small point of use drinking water systems.
How many gallons does it use in the backwash?
Around fifty gallons. It could be slightly more or less depending upon water pressure.
How long does the backwashing last?
It lasts approximately 10 minutes.
What is the flow rate of the backwash water?
5-7 gallons per minute flow rate
Does it have to backwash every day?
It's advisable to backwash daily but not mandatory. Often times systems on municipally treated water backwash once every three or four days. Systems on wells are urged to backwash daily. The frequency of backwash depends greatly upon the quality of water.
