Pentair Manifold Bypass Valve Kit for MasterTemp/Max‑E‑Therm – OEM fit, corrosion‑resistant valves

The Pentair Manifold Bypass Valve Kit for MasterTemp/Max‑E‑Therm lets you divert water flow safely around the heater manifold to simplify maintenance and optimize heater performance.

If you operate a Pentair MasterTemp or Max‑E‑Therm pool heater, this factory‑matched bypass valve kit provides the plumbing control needed to isolate the heater manifold without shutting down the entire system. Designed to fit the specified Pentair heater models, the kit helps you manage flow for cleaning, repair, or seasonal adjustments while maintaining correct water circulation and protecting heater components.

How does the bypass valve kit help during heater maintenance?

Installing the Pentair bypass valve kit enables technicians and owners to reroute water around the heater manifold so service tasks can be performed without draining the system. It reduces downtime and makes access to internal heater parts easier and safer for routine work.

• Isolates heater manifold for inspection and repair
• Maintains pool circulation while servicing the heater
• Reduces need for system shutdowns and water loss

Will this kit fit my MasterTemp or Max‑E‑Therm unit?

The kit is made specifically for Pentair MasterTemp and Max‑E‑Therm heater families and matches the OEM plumbing layout and connections. Always compare your heater model number and existing manifold arrangement to the kit part number to confirm compatibility before ordering.

• Designed for Pentair MasterTemp and Max‑E‑Therm heaters
• Factory‑matched connections for proper fitment
• Part number reference: 77707‑0001 for verification

What components and benefits are included in the kit?

The Pentair manifold bypass valve kit contains the valves and fittings required to create a controlled bypass around the heater manifold. Components are engineered to withstand pool water conditions and integrate with existing pump and heater plumbing to maintain correct flow balance.
