Questions & Answers
- Are the Oberdorfer Pumps warranted against corrosion damage?
- Damage resulting from electrolytic corrosion is not covered by Oberdorfer Limited Warranty. Galvanic corrosion (electrolysis) can cause serious damage to any metal component in the water.
- What is galvanic corrosion?
- Galvanic corrosion is the deterioration of metals from the effects of electrolytic action. When different metals are immersed in a conductive fluid like salt water, an electric current is produced, similar to the action of a battery. The softer metal will be the first to deteriorate or corrode.
- Can Galvanic corrosion occur in fresh water?
- Galvanic corrosion can occur in fresh or salt water, but, salt, brackish and polluted waters can accelerate the galvanic corrosion process.
- Do self-sacrificing anodes prevent or reduce damage from galvanic corrosion?
- Self-sacrificing anodes can be mounted to a craft to help prevent or reduce damage to metal components from galvanic corrosion.
- How often should sacrificial zinc anodes be replaced?
- It is the craft owner’s responsibility to periodically inspect and replace the sacrificial zinc anodes. If the anode has deteriorated 50% or more, it should be replaced for continued protection. DO NOT paint an anode, its fasteners or its mounting surface. Paint and improper contact with its mounting surface will reduce the anode’s protection capabilities. Make sure the contact between the anode and its mounting surface is clean and secure.
