Frequently Asked Questions

How do I know when my HydroChlor 3000 cell needs replacing?

Common signs include the chlorinator displaying a cell fault or low output warning, the pool consistently testing low in chlorine despite the unit running at high output, visible scaling or damage to the cell plates, or the cell failing to generate chlorine after cleaning. Most cells last 3–5 years depending on water chemistry, usage, and maintenance. If acid washing no longer restores output, the cell needs replacement.

Is this a genuine Waterco cell?

Yes — this is a 100% genuine OEM Waterco replacement cell (part no. 64428730), not an aftermarket substitute. Genuine cells ensure correct plate dimensions, electrical compatibility, and reliable chlorine output for your HydroChlor 3000 system.

How do I install the replacement cell?

Turn off the chlorinator and pool pump before starting. Unscrew the existing cell from the cell housing, disconnect the electrical connector, and reverse the process with the new cell. No adjustments to the control box are required — the replacement cell is a direct drop-in. If you need guidance, contact us before ordering.

How do I extend the life of my new cell?

Maintain correct salt levels as specified by Waterco for the HydroChlor 3000 (typically 4,000–6,000 PPM). Keep pH between 7.2 and 7.6 — high pH accelerates calcium scaling on the plates. Inspect and acid wash the cell every 3–6 months to remove calcium deposits. Avoid running the cell at maximum output continuously if your pool’s chlorine demand does not require it.
