Signs of Acid Water
It's often difficult to tell if you have acidic water. Look for the following signs around your home. If you see any of these, you have acidic water. 

  • Greenish/blue stains in your sink, toilet or bathtub.
  • Greenish/blue stains on or between tiles in your shower.
  • Pinhole leaks in pipes.
  • Faucets and fixtures that are corroded and/or continuously leak.
  • Fragile pipes with thin walls.

What is Acid Water?
Water is tested for acidity just like the water in a swimming pool, by using the pH level.* 7.0 is the neutral level for pH. If your pH level is 6.8 or below, your water is considered acidic. 

Acidic water is highly corrosive to just about everything it comes into contact with. Acidic water will eat away at pipes, both metal and plastic. It eats away at faucets, valves and washers causing them to leak or run continuously. Appliances, such as dishwashers, icemakers, washing machines, garbage disposals, etc., will be damaged by acidic water. Naturally, acidic water will destroy sink faucet and drain fixtures, tub faucet and drain fixtures, and the internal works on commodes. 

We've had clients who've had to replace all the plumbing fixtures in their home before calling us for help. Other clients have had to re-plumb their entire home due to leaking pipes. Plumbing work is expensive! One of our Acid Filters can protect your home and investment.

(* The pH scale is measured by the amount of hydrogen ions and determines the level of acidity or alkanity of a substance. It ranges from 0 to 14. The scale is logarithmic, which means that a difference of one pH unit corresponds to a change of 10 times the strength. Therefore, a pH of 5 means the solution is 100 times more acidic than a pH of 7.)

How does an Acid Filter work?
An Acid Filter is filled with a specially designed media. The acidic water enters the top of the unit and flows through the media. The media reduces the acidity of the water, changing it to a more neutral level. Clean, clear, neutral water is then passed from the filter and into your water system. 

About every 4 days the filter removes accumulated impurities that have been trapped inside. This is done by an automatic self-cleaning cycle called backwashing. This backwash cycle cleans the media bed, flushing any sediment or contaminants out of the filter. Once the backwash cycle has ended, the filter returns itself to normal operation. 

The amount of media inside the filter must be checked and replenished periodically (typically every 6 months) to maintain proper and efficient operation. We can do this routine maintenance or we'll be happy to show you how to do it. If you wish to do the maintenance on your own, we'll even provide you with an instruction guide. 

A simple water test, that only takes a few minutes, can confirm whether or not you have acidic water. Metro Water Filter International offers a free test of your water without obligation. Please give us a call and we'll set up an appointment to test your water on site.
