Raypak Header Return Polymer

This part is designed for Raypak heater models in the 185-405 and 206-407 series. Before purchasing, verify your heater's model number on the data plate to ensure it falls within these ranges.

Polymer is used because it is highly resistant to the corrosive nature of pool chemicals and the harsh environment inside a heater. This material choice helps prevent rust and scale buildup, which can compromise the water path over time.

If you are comfortable with basic pool equipment maintenance, this is a straightforward replacement. However, because it involves the water path of your heating system, ensure the power and water supply are completely shut off before starting, and consider consulting a professional if you are unsure about the plumbing connections.

You should inspect your header return if you notice water leaking from the heater housing, visible cracks in the plastic, or if the unit is losing pressure. These issues often indicate that the material has degraded and is no longer maintaining a proper seal.

This listing is for the header return component itself. It is standard practice to inspect your existing O-rings and gaskets during installation; if they appear worn or flattened, we recommend purchasing fresh seals to ensure a watertight fit.
