How To Clean The Titanium Electrodes (And Electrode Chamber) In A City POE
Items Needed To Clean The Titanium Electrodes in a city POE:
- 5 gallon bucket
- Liquid muriatic acid (hydrochloric acid), or Acid Magic (Muriatic Acid Replacement)
1) First, turn off the water to the house and close valve so water doesn't leak when the chamber is taken out of the plumbing line.
2) Slip the wires off of the metal tabs on the outside of the chamber.
3) Unscrew the union ends at either end of the chamber. Be careful not to crack the chamber. If the ends are screwed in too tightly to turn, use a strap wrench. *Do not use channel locks!.
4) Take the chamber out of the plumbing line, but do not remove the electrodes. The entire chamber gets submerged for cleaning.
5) Create a solution of 5 parts water to 1 part liquid muriatic acid, or Acid Magic. Pour in the water first and then the acid to keep from splashing acid.
6) Submerge the entire chamber in the acid/water solution for 5 -10 minutes. The chamber will bubble. When the bubbling stops the electrodes and chamber are clean. *Do not use anything to scrub or scrape the electrodes which will damage them).
7) Remove the chamber and rinse. Replace the chamber into the plumbing line so that the titanium electrodes are first in the flow of the water and copper electrodes are last. Do not over tighten. Hand tight is sufficient. Tighten until there is no more leaking.
8) Reconnect the wires. Red and Green wires go to the copper electrodes. Black and White wires go to the titanium electrodes.
9) Open the valves and turn the water back on to the house to put the system back into service.
