How do you clean a rusty geyser?

Cleaning a rusty geyser involves several steps to remove the rust and prevent it from recurring. Here’s a guide on how to clean a rusty geyser:

  1. Turn Off Power: Before starting any cleaning or maintenance procedures, ensure that the power to the geyser is turned off at the circuit breaker or fuse box. This prevents the risk of electric shock while you’re working.
  1. Drain the Tank: Turn off the water supply to the geyser and allow the tank to cool down. Once the water has cooled, attach a hose to the drain valve at the bottom of the tank and drain the water completely. Be sure to open a hot water tap in the house to help facilitate drainage and prevent vacuum formation.
  1. Flush the Tank: After draining the tank, flush it with clean water to remove any remaining sediment, debris, and loose rust particles. You can do this by refilling the tank partially and then draining it again. Repeat this process until the water runs clear.
  1. Scrub the Interior: Use a non-abrasive brush, such as a nylon brush, to scrub the interior surfaces of the tank. Focus on areas with visible rust deposits, particularly around the heating element and at the bottom of the tank. Be gentle to avoid damaging the tank’s lining.
  1. Apply a Rust Remover: For stubborn rust stains, you can use a commercial rust remover specifically designed for use in water heaters. Follow the manufacturer’s instructions carefully, as these products can vary in application and effectiveness.
  1. Rinse Thoroughly: After using a rust remover, thoroughly rinse the tank with clean water to remove any residue from the cleaning process. Repeat the flushing process as necessary until the water runs clear and there are no traces of the rust remover left.
  1. Inspect and Replace Anode Rod: The sacrificial anode rod in the geyser is designed to attract corrosive elements and protect the tank from rusting. If the anode rod is heavily corroded or depleted, it should be replaced. Inspect the anode rod during the cleaning process and replace it if necessary.
  1. Restore Power and Refill: Once the tank is clean and the interior surfaces are free of rust and debris, close the drain valve and turn the power back on at the circuit breaker or fuse box. Allow the tank to refill with water and heat up to the desired temperature.

Regular maintenance, including periodic flushing and inspection of the geyser, can help prevent rust buildup and prolong the lifespan of the appliance. If you’re unsure about any aspect of cleaning or maintaining your geyser, it’s best to consult a professional plumber or technician for assistance.
