Zodiac LXI Rear Header

No, this specific part is engineered exclusively for the Zodiac LXi Low NOx heater series. It will not fit other Zodiac or Jandy heater models, so please verify your heater's model number before purchasing.

Yes, this package comes with the rear header itself, along with all the necessary hardware and gaskets required for installation. You should not need to purchase additional components to complete the swap.

If you are comfortable with basic pool equipment maintenance and plumbing, this is a straightforward direct-fit replacement. However, because this involves gas heater components, we recommend hiring a certified pool technician if you are not confident in your ability to ensure a proper, leak-free seal.

The rear header is essential for managing water flow through the heat exchanger. Over time, these components can corrode or crack, which leads to leaks and reduced heating efficiency; replacing it ensures your system maintains proper pressure and heat transfer.

The most common signs are visible water leaks around the back of the heater, rust accumulation on the header housing, or a drop in your pool's heating performance. If you notice water pooling under the unit, it is time to inspect the header for cracks or gasket failure.
