Key Benefits + Heater Water-System Fitment
- Swimables replacement manifold bypass valve for compatible Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters.
- Cross-references Pentair part number 77707-0001.
- Installs in the heater water manifold as the internal bypass-valve component.
- Useful when heater troubleshooting or inspection has confirmed the internal bypass valve requires replacement.
- Part-number matching helps reduce wrong-part orders on heater water-system repairs.
Quick Product Summary
The Swimables SW-41-001 is a replacement manifold bypass valve for compatible Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters. Swimables cross-references SW-41-001 to industry part number 77707-0001, and Pentair lists 77707-0001 as the Manifold Bypass Valve Kit or Manifold Bypass Valve Package in its MasterTemp and Max-E-Therm water-system replacement-parts documentation. The internal bypass valve is located in the heater manifold and is one of the water-system components Pentair identifies during troubleshooting when heater temperature or flow-related problems persist. This replacement is best for service professionals and equipment owners who have confirmed 77707-0001 as the required part. Verify the exact heater model, header/manifold design, and original part number before ordering.
Best For
Replacing a confirmed 77707-0001 internal manifold bypass valve on compatible Pentair MasterTemp and Sta-Rite Max-E-Therm heaters.
Why This Matters
- The bypass valve is part of the heater water manifold and must operate correctly as part of the overall water system.
- Pentair troubleshooting guidance specifically calls for checking the internal bypass valve when certain high-limit or water-temperature problems persist.
- Using the correct bypass-valve kit helps maintain the intended heater water-system configuration.
- Matching SW-41-001 to 77707-0001 is more reliable than ordering by appearance alone.
Common Signs You Need This / Use This When
- Your heater parts diagram or existing component identifies 77707-0001.
- Inspection has found the internal manifold bypass valve damaged, worn, stuck, or otherwise unsuitable for continued service.
- Heater troubleshooting has directed you to verify the internal bypass valve and diagnosis confirms replacement is required.
- You are servicing a compatible MasterTemp or Max-E-Therm water manifold and need the listed bypass-valve replacement.

Compatibility / Fitment Notes
Swimables identifies SW-41-001 as a MasterTemp / Max-E-Therm style bypass valve and cross-references it to 77707-0001. Pentair lists 77707-0001 in both MasterTemp and Max-E-Therm water-system replacement-parts documentation. For ASME heaters, header design and manufacture date matter because Pentair identifies a different bypass-valve kit for certain older header designs. Confirm the heater model, original part number, and manifold/header design before purchase.
Installation / Use Notes
Pool-heater service involves hot water, electrical, and gas-fired equipment. Follow the heater manufacturer’s service instructions, allow the heater to cool, shut off the filter pump and electrical power, and follow all applicable gas shutoff procedures before opening the heater. If the heater is below pool water level, isolate the equipment as required before opening the water system. Installation and heater diagnosis should be performed by a qualified pool-heater service professional when appropriate.
Buy with Confidence
Benchmark Pool Supply helps customers identify pool-heater replacement parts using real equipment knowledge and part-number matching. For internal water-system parts like SW-41-001, we focus on the exact cross-reference, heater family, and manifold design so you can verify the correct replacement before ordering.
Frequently Asked Questions
What does the Swimables SW-41-001 replace?
Swimables cross-references SW-41-001 to Pentair 77707-0001, the manifold bypass valve kit used in compatible MasterTemp and Max-E-Therm heater water systems.
Where is the SW-41-001 bypass valve installed?
It is an internal bypass-valve component in the heater water manifold. Pentair parts diagrams identify 77707-0001 in the water-system manifold assembly.
Does SW-41-001 fit both MasterTemp and Max-E-Therm heaters?
Yes, Swimables lists SW-41-001 for MasterTemp and Max-E-Therm style applications, and Pentair lists 77707-0001 in replacement-parts documentation for both heater families. Verify your exact model and original part number before ordering.
Can a bypass-valve problem contribute to heater temperature or flow faults?
It can be part of the diagnosis. Pentair troubleshooting guidance directs technicians to verify the internal bypass valve when certain high-limit or water-temperature problems persist, but the complete water system should be diagnosed before replacing parts.
What should I verify before ordering SW-41-001?
Confirm the heater model, original 77707-0001 part reference, and the manifold/header design. This is especially important on ASME heaters because older header designs may use a different bypass-valve kit.
