How To Replace Copper Electrodes In A City POE
Materials needed to replace the copper electrodes in a city POE:
- Clear silicone
- Electric screwdriver
1) 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 on each end of the chamber being careful not to crack the chamber. If the ends are too tight to unscrew by hand, use a strap wrench. *Do not use channel locks!!
4) Unscrew the copper electrodes from the chamber and allow them to drop out. Don't let them scratch the titanium electrodes.
5) Put one new copper electrode in at a time.
6) Balance the new copper electrode over the screw hole and attach the new electrode into the chamber.
7) Repeat for the other copper electrode
8) Put a bead of silicone around the outside of the rubber grommet on the outside of the electrode chamber - to prevent leaking from the screw holes.
9) Put the chamber back in the plumbing line so that the titanium electrodes are first in the flow of water and the copper electrodes are last. Do not over tighten. Hand tight is sufficient. Tighten until there is no leaking.
10) Attach the wires to the chamber. Red and Green wires go to the copper electrodes. Black and White wires go to the titanium electrodes.
11) Open the valves and turn the water back on to the house to put the system back into
