Know before you buy
No, this specific kit (part number 475943) is designed exclusively for the Pentair UltraTemp ETi hybrid gas heater models. It is not universal and should not be used with other Pentair heater lines.
You should consider a replacement if you notice persistent leaking from the valve, if the valve fails to open when pressure builds, or if your heater displays error codes related to water flow or pressure. If the valve is physically corroded or stuck, it is time for a new unit.
No, this is a purely mechanical component. It does not require any electrical connections or integration with the heater’s control board.
The installation process is straightforward and designed for direct replacement. However, because it involves the plumbing of your pool heater, you should feel comfortable working with basic hand tools and water-tight seals; if you are unsure, a pool service professional can install it quickly.
Using a genuine Pentair part ensures the valve is calibrated specifically for the pressure tolerances of the UltraTemp ETi system. Aftermarket parts may not meet the exact specifications, which could lead to improper pressure regulation and potential damage to your heat exchanger.
