## Summary description

Replacement anode rod Biawar, model 18625, diameter fi21.3 mm and length 900 mm with a 3/4" threaded connection and integrated gasket. Designed to protect water heaters and boilers from corrosion by providing sacrificial protection. Suitable for use in domestic and light-commercial hot-water systems where a 3/4" anode connection and these dimensions are required.

## Long description

Replacement anode rod Biawar fi21.3×900 mm with 3/4" thread and integrated gasket is a sacrificial magnesium anode designed to reduce corrosion in domestic and light-commercial hot-water storage tanks and boilers. The product has a nominal diameter of 21.3 mm and an overall length of 900 mm, with a 3/4" threaded connection that fits systems requiring this standard size. The integrated gasket ensures a sealed connection to prevent leaks at the tank fitting.
Advantages
This Biawar anode rod provides galvanic protection by corroding in place of the steel tank, extending the service life of the water heater. Its standardized 3/4" thread simplifies installation in compatible tanks, while the integrated gasket reduces the need for additional sealing materials. The long 900 mm length enables protection across a significant portion of the tank interior where magnesium anodes are appropriate.
Suitable for
 Domestic hot-water storage tanks with a 3/4" anode connection
 Light-commercial boilers and water heaters requiring a 900 mm anode
 Replacement of depleted sacrificial anodes to prevent tank corrosion
 Systems where a 21.3 mm diameter anode is specified
Key specifications
 Anode material: magnesium (sacrificial anode)
 Nominal diameter: 21.3 mm
 Overall length: 900 mm
 Threaded connection: 3/4" external thread
 Integrated gasket for leak-resistant connection
How to use
Turn off the water supply and power to the heater before beginning replacement. Drain sufficient water from the tank to lower the water level below the anode access point. Unscrew the old anode using an appropriate wrench or socket on the hexagon fitting if present. Clean the anode opening and inspect the tank interior for signs of corrosion. Apply the integrated gasket and screw the new Biawar anode rod into the 3/4" threaded connection until hand-tight, then finish with a wrench to the manufacturer-recommended torque if available. Refill the tank, restore power, and check for leaks at the connection.
Usage recommendations
For optimal corrosion protection, inspect the anode rod at regular intervals (typically every 1–3 years depending on water quality and usage) and replace it when the anode core is significantly depleted or heavily pitted. Use the specified 3/4" thread and 21.3 mm diameter to ensure a proper fit; if tank fittings differ, consult the appliance manual or a service professional before installation.
