Lrichy RV Water Heater Repair Kit — Suburban 5‑in‑1 9.25" Magnesium Anode & 520900 Element with Flush Wand

The Lrichy 5-in-1 RV Water Heater Repair Kit is a complete Suburban-compatible maintenance set that replaces the anode rod and heating element while providing a professional flush wand and tools for deep cleaning and corrosion protection.

Keep your Suburban RV water heater running efficiently with a single kit that supplies the parts and tools needed for routine preventive maintenance and straightforward repairs. This set bundles a 9.25" magnesium anode rod, a 520900 screw-in heating element, a stainless flush wand, dual hex wrench, and Teflon tape — all designed to match Suburban DE/DEL/DEM/DELC/DEC series tanks. Replacing sacrificial components and removing sediment helps extend tank life and maintain hot water performance on the road.

How will this kit improve my RV water heater’s lifespan?

Replacing the anode rod prevents internal corrosion by sacrificially attracting corrosive elements, while the new heating element restores proper heating efficiency. Regular flushing with the included wand clears sediment that accelerates wear and reduces heat transfer.

• 9.25" magnesium anode sacrifices itself to slow tank corrosion
• 520900 heating element matches OEM specs for reliable performance
• Flush wand removes scale and sediment to prevent hotspots
• Simple swap procedure with the supplied dual hex wrench

Is this kit compatible with my Suburban RV water heater model?

The components are engineered to fit common Suburban models and follow original dimensions for a sealed, leak-free installation. The anode uses a 3/4" NPT thread and the element is the 520900 screw-in style commonly found in DE, DEL, DEM, DELC, and DEC tanks.

• 9.25" anode rod with 3/4" NPT thread for Suburban tanks
• 520900 element designed to replace factory heating elements
• Compatible with many DE/DEL/DEM/DELC/DEC series Suburban models

What steps are involved in replacing parts and cleaning the tank?

The kit is built for DIYers and service technicians: shut off power and water, drain the tank, remove the old element and anode with the dual hex wrench, install new parts with Teflon tape, then run the flush wand to clear debris. The sequence minimizes leaks and readies the system for safe operation.

• Turn off power and gas, then drain the water heater tank
• Remove old anode and element using the included dual hex wrench
• Apply Teflon tape and install new anode and 520900 element
• Use the curved stainless flush wand to blast out sediment

What materials and durability features does the kit offer?

The anode rod is cast from magnesium alloy to maximize sacrificial protection against rust and odors, and the heating element resists high temperatures and scale buildup. The flush wand uses stainless-steel construction for corrosion resistance during repetitive cleanings.

• Magnesium anode for effective corrosion control
• Robust 520900 heating element built for heat and scale resistance
• Stainless-steel flush wand with curved tip for deep cleaning
• Includes Teflon tape and dual hex wrench for leak-free installation

Who is this for: This Lrichy kit is aimed at RV owners, fleet managers, and RV technicians who service Suburban water heaters and want a single purchase to perform routine maintenance or on-the-spot repairs. It’s suitable for DIYers who are comfortable with basic RV plumbing and electrical safety, and for professionals who need matching OEM-style replacement parts and reliable cleaning tools to keep water heaters performing well while minimizing downtime.
