Product details
The Pentair 475984 is the membrane pad replacement kit for the ETi 400 heater. It is a genuine Pentair product.
How Pentair supplies ETi 400 parts
Service parts for the ETi 400 are sold as individual replacement kits rather than as loose components, so a repair is usually a matter of matching the symptom to the right kit and fitting it complete. This listing is the membrane pad kit.
Before you order
Check the data plate and confirm the heater is an ETi 400. Heater components are specific to their model and do not carry across the range. Because this is a gas fired appliance, the work belongs with a qualified technician, and the gas supply and electrical power should both be isolated before the cabinet is opened.
