Replacement of water heater anodes is a necessary operation in ensuring that your water heat system serves for an extended period. Aluminium heater anode components are made to prevent corrosion by water. They do this by corroding themselves to keep the water heater tank safe and intact. When the anodes are missing, the water heater tank is corroded affecting its performance and lifetime. The lifetime of the anode on the other hand depends on the purity of water that is heated, the maximum temperature and frequency at which water is heated within the tanks, and the quality of water tank being used. Use these tips to replace your aluminium water heater anode and get it working.
What is Needed
You will need a masking tape, garden hose, a tank cleaner, and a wrench to kick off the replacement process.
Shut down Power Supply to the Heater
Before making any installation attempt as with all electrical appliances, ensure to shut down power supply to the heater. This will offer a safer working environment by preventing electric shocks during the installation process.
Perform a Clear Assessment
You must begin by clearly assessing whether the water heater anode needs to be replaced or not. A life expectancy for your water heater anode may be offered by manufacturer's but factors of water quality and usage still have an influence on how often it should be replaced. The aluminium anode continues to erode over time and must be checked once in a while to see if it should be replaced. It should not be left to brittle too much and at the same time should not be replaced too soon as this will be a waste of resources.
Drain Your Tank
After assessment has confirmed that your anode needs replacement, drain the water heater tank to almost halfway for ease of operation using a regular garden hose or a tank drain.
Remove Old and Replace New Anode
Use a wrench to loosen the fitting positioned at the base of the anode. Be careful to remove the whole fitting as slipping of the wrench may break the fitting and complicate the removal process. After removing the old anode, replace the new anode by screwing it in. Tighten it well in its position then use a masking tape to ensure all the threads are well sealed.
You may also consider washing the heater tank after the installation process to do away will all accumulations of dirt particles from impurities of water.
