ATEEfaee Suburban RV Water Heater Repair Kit — 120V 1440W Element, Thick 21mm Magnesium Anode & Dual Socket

Complete maintenance kit for Suburban-compatible RV water heaters including a 120V 1440W heating element, larger-diameter magnesium anode rod, dual socket wrench, and PTFE tape.

This ATEEfaee repair kit is built for routine service and preventative upkeep of Suburban-style RV water heater tanks. It bundles a replacement heating element matched to common Suburban SW series models, a sacrificial magnesium anode rod with extra thickness for extended protection, a dual-ended socket to fit both components, and PTFE tape for a tighter seal. The kit is intended for owners or technicians who want a single package to refresh heating performance and reduce internal corrosion risk during scheduled maintenance.

Which RV water heaters does this kit fit?

The heating element is compatible with many Suburban SW series units (SW4DE, SW6DE, SW10DE, SW12DE) and replaces part numbers 520900, 520789, and 232794. Confirm your specific model and element style before ordering to ensure a direct fit.

• Replaces Suburban part numbers 520900, 520789, 232794
• Engineered for Suburban SW4DE, SW6DE, SW10DE, SW12DE series
• Designed as a direct replacement heating element for 120V systems

How does the magnesium anode rod protect my water heater?

The included magnesium anode rod is a sacrificial metal piece that corrodes preferentially to the steel tank, slowing internal rust formation. This kit’s anode has a thicker 21 mm diameter and a 235 mm length, providing more sacrificial material than slimmer rods for extended service life when installed correctly.

• Magnesium composition helps reduce tank corrosion over time
• Thicker 21 mm diameter offers increased sacrificial mass
• 3/4" NPT male thread and 235 mm length for common Suburban openings

What tools and parts are included for installation?

Everything needed for a standard maintenance job is in the box: a 120V 1440W heating element, a dual-ended socket (1-1/2" and 1-1/16"), the magnesium anode rod, and PTFE tape for sealing threads. The dual socket lets you remove and install both the element and the anode without switching tools.

• Dual-purpose socket: 1-1/2" for element, 1-1/16" for anode
• PTFE tape included to help prevent leaks at threaded connections
• High-quality gasket included for secure element mounting

Are there any installation cautions I should know?

Before starting, verify your water heater model and the anode thread size. The 21 mm (0.83") diameter anode is slightly larger than some standard rods and may need careful alignment and gentle tightening to avoid cross-threading. Always drain and depressurize the tank and follow safety procedures for electrical disconnection prior to servicing.

• Confirm model compatibility and 3/4" NPT thread fit first
• Drain and depressurize the tank before removing the element
• Use included PTFE tape and tighten gently to avoid thread damage

Who is this for? This ATEEfaee Suburban RV Water Heater Repair Kit is aimed at RV owners, campers, and service technicians who perform routine maintenance or part replacement on Suburban-style water heaters. It’s especially useful for those who prefer a single, ready-made kit that supplies a replacement heating element, an enhanced magnesium anode, and the correct tools to complete the job safely and neatly.
