How To Replace The Copper Electrodes In A Spa System

Items Needed To Replace The Copper Electrodes In A Spa System:

  • Electric Screwdriver
  • Clear Silicone
  • Strap Wrench (Possibly Needed To Loosen Unions)

1)  Turn off the electrical power by switching off the breaker or switching off the disconnect.  

2)  If also draining the spa, remove the filter and drain the spa using a garden hose at the bottom of the filter housing.

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.  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.  The copper electrodes are first in the flow of water, the titanium electrodes last.

11) Refill the spa, put the clean filter in, open the valves, switch on the electrical power, and follow the Start Up procedure.
