## Summary description

KOSPEL AMW 22/400 is a magnesium anode rod designed to protect water heaters and storage tanks from corrosion. The AMW.400 model features a 400 mm length (22 mm diameter implied by model code) and a 3/4" threaded plug for installation. It provides sacrificial corrosion protection, extending the service life of tanks and heating systems and is used during maintenance or replacement of deteriorated anodes.

## Long description

KOSPEL AMW 22/400 is a magnesium anode rod designed to provide sacrificial corrosion protection for domestic water heaters and storage tanks. The AMW.400 model has a 400 mm length and installs using a standard 3/4" threaded plug. The magnesium composition gives effective protection against electrochemical corrosion by attracting corrosive elements to the anode, thereby preserving the structural metal of the tank and heating elements. The rod is intended for routine maintenance or replacement of depleted anodes to help extend service life of hot water systems.
Advantages
The KOSPEL AMW 22/400 offers straightforward mechanical compatibility with tanks that accept a 3/4" anode plug and a compact 400 mm length suitable for many domestic heaters. Magnesium construction provides strong sacrificial protection for steel tanks and heating components in typical potable hot-water environments. Installation and replacement are simple, which reduces downtime during maintenance and helps maintain system efficiency over time.
Suitable for
 Domestic electric and gas water heaters with 3/4" anode access
 Hot water storage tanks requiring magnesium sacrificial protection
 Replacement during regular maintenance when the original anode is corroded
 Systems where a 400 mm anode length fits the tank geometry
Key specifications
 Material: magnesium sacrificial anode
 Length: 400 mm
 Connection: 3/4" threaded plug
 Intended function: corrosion protection for water heaters and storage tanks
 Typical application environment: potable hot water systems
How to use
Before installation, isolate the water heater and relieve pressure according to the heater manufacturer's instructions. Access the anode port and remove the old or depleted anode using appropriate tools. Insert the KOSPEL AMW 22/400 anode rod into the 3/4" port and tighten the plug to the specified torque to ensure a secure seal without deforming the thread. Re-pressurize the system and check for leaks. Regular inspection of the anode during scheduled maintenance will indicate when replacement is next required.
Usage recommendations
For optimal protection, use the KOSPEL AMW 22/400 in systems compatible with a 400 mm magnesium anode and perform visual checks every 12 months or according to local water conditions and manufacturer's maintenance intervals. Replace the anode when its diameter is significantly reduced or when heavy corrosion is visible. Follow safe isolation and depressurization procedures before any work on the heater.
