Pentair Manifold Mount Replacement | 474200
Pentair Basic Manifold Kit for MasterTemp and Max-E-Therm Heaters | 474200
Restore the water-side manifold connection on compatible Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters with the Pentair 474200 Basic Manifold Kit.
What is the Pentair 474200 used for?
The Pentair 474200 is used to repair or replace the basic water manifold components on compatible MasterTemp and Max-E-Therm gas pool heaters. The manifold directs pool water through the heater's heat exchanger and provides the sealed connection between the heat exchanger, internal water components and external plumbing.
Compatible Heater Families
- Pentair MasterTemp pool and spa heaters
- Sta-Rite Max-E-Therm pool and spa heaters
- Compatible heater configurations that specify part 474200
- Water-side manifold and heat-exchanger service applications
Verify Before Ordering
- Complete heater model number
- Heater BTU rating
- Natural gas or propane configuration
- Standard, HD or ASME construction
- Existing manifold and parts diagram
Product Details
What is included with the Pentair 474200 Basic Manifold Kit?
Pentair identifies the 474200 Basic Manifold Kit as covering water-system components shown as items 3, 5 and 10 through 14 in the applicable manufacturer parts breakdown.
- Basic heater water manifold components
- Manifold and tube-sheet sealing components within the kit scope
- Connector tube components included within the listed assembly group
- Associated O-rings, fasteners and installation hardware supplied by Pentair
Is 474200 a replacement for connector tube kit 77707-0017?
Pentair 474200 is a broader basic manifold kit rather than a direct one-piece supersession for 77707-0017. However, the connector tube components identified under 77707-0017 are included within the item range Pentair specifies for the 474200 kit.
This makes 474200 a practical OEM assembly-level repair option when the connector tube kit alone is discontinued or unavailable.
What is not included with the basic manifold kit?
Part 474200 is a basic manifold kit, not a fully dressed or model-specific complete manifold assembly. Some existing heater components may need to be transferred or ordered separately.
- Water pressure switch
- Thermal regulator assembly
- Bypass valve components not included within the basic kit scope
- Model-specific sensors or safety switches
- External plumbing unions or adapters not supplied with the kit
- Additional components required by HD or ASME configurations
Inspect all transferred components for cracking, corrosion, scale buildup and heat damage before reuse.

Installation and fitment guidance
Heater parts can vary by model, production date, fuel configuration and water-system design. Compare part number 474200 with the heater's original Pentair parts diagram before installation.
- Shut off electrical power to the heater
- Close the manual gas supply valve
- Turn off the circulation pump
- Allow the heater to cool completely
- Drain and isolate the heater water system
- Clean all heat-exchanger and manifold sealing surfaces
- Lubricate O-rings only with a compatible manufacturer-approved lubricant
- Follow the Pentair tightening sequence and torque specifications
- Pressure-test the water system before returning the heater to service
Frequently Asked Questions
Is Pentair 474200 just a manifold mounting bracket?
No. Pentair identifies 474200 as a Basic Manifold Kit for compatible heater water systems. It is more than an individual bracket, mount or structural support.
Does 474200 fit every Pentair MasterTemp heater?
No universal fit should be assumed. Compatibility must be confirmed using the complete heater model, BTU rating, manufacturing configuration and Pentair parts diagram.
Does this fit Sta-Rite Max-E-Therm heaters?
Part 474200 is used with compatible Sta-Rite Max-E-Therm heater water systems where the manufacturer specifically identifies this part number.
Is this a complete ready-to-install manifold assembly?
No. This is the basic manifold kit. Depending on the heater and the condition of the existing components, some switches, regulators, bypass components, sensors or plumbing connections may need to be transferred or purchased separately.
Can this be used when 77707-0017 is discontinued?
Yes, it may provide an OEM assembly-level repair path because Pentair includes the connector tube component group within the listed scope of the 474200 Basic Manifold Kit. Confirm the exact heater configuration before ordering.
Professional Installation Recommended
Gas pool-heater repairs involve pressurized water, electricity, combustible gas and high-temperature components. Installation should be completed by a qualified pool-heater, gas-appliance or HVAC service professional.
