Product details

The Zodiac R0511400 is the genuine replacement electrode for the AquaPure Ei 35 salt chlorine generator. It is the part that actually makes chlorine from the salt in the water.

Why the electrode is what wears out

Everything else in a salt system, the power supply and the plumbing, tends to outlast the cell. The electrode plates carry the current that converts salt to chlorine, and that coating gradually gives up. The symptom is familiar: salt level reads fine, settings are turned up, and the pool still cannot hold a residual. Replacing the electrode is what brings output back.

Before you order

Confirm your unit is an Ei 35, since the Ei series uses different electrodes by size. The R0738500 o-ring is not supplied with this electrode, so inspect the old seal while the cell is apart and add a fresh one if it is flat, cracked or hardened.

Questions and answers

What people ask about this product, answered by our pool techs.

Does the o-ring come with it?
No. The R0738500 o-ring is not included with this electrode, so order one separately if the existing seal is worn.
Which system does this fit?
The AquaPure Ei 35. Match the model on your unit before ordering, since the Ei series electrodes differ by size.
Why would I need a new electrode?
Electrodes are consumable. The plates lose their coating over years of service, output drops, and the system can no longer hold a chlorine residual even with salt and settings correct.
Is this a genuine part?
Yes. It is the Zodiac OEM electrode, part number R0511400.
