Dial Manufacturing 5157 Zinc Anode

Product Description

The DIAL MANUFACTURING 5157 is a zinc anode replacement part used to protect metal components in water-contact systems from galvanic corrosion. Zinc anodes work through sacrificial corrosion - the zinc corrodes preferentially, extending the service life of the surrounding metal tank, fitting, or heat exchanger. This type of part is a routine maintenance item for pool, spa, and water heater systems. Plumbers, pool service technicians, and water heater service techs are the primary installers. Sold as a single unit.

Zinc anodes are standard consumable components in systems where dissimilar metals are present in a water environment. Typical applications include residential and light commercial water heaters, pool and spa equipment, and plumbing assemblies with copper or steel components exposed to standing water. Regular anode inspection and replacement is a key preventive maintenance step to avoid premature tank or component failure.

Key Features

• Sacrificial zinc construction protects surrounding metal components from galvanic corrosion
• Sold as a single replacement unit
• Designed as a routine maintenance consumable for water-contact systems
• Compatible with pool, spa, and water heater service applications

Compatibility

Designed as an OEM-style replacement zinc anode for use in residential and light commercial water heaters, pool equipment, and plumbing assemblies requiring sacrificial anode protection.

Installation Notes

Zinc anode replacement is typically performed by a licensed plumber or qualified service technician. Always shut off the water supply and relieve system pressure before removing the existing anode. Follow applicable local plumbing codes and manufacturer service procedures when replacing sacrificial anode rods. Inspect the anode annually and replace when significantly depleted to maintain corrosion protection.
