Paloma Gas Water Heaters should be flushed every 3-6 months to try to help preserve the appliance and its unique parts.

Drain your geyser

  • Turn off the water heater at the plug.
  • Open a hot water tap – preferably a shower faucet.
  • Unscrew the two drain plugs – one for the hot outlet and the other for the cold inlet, on the underside of the geyser. The water will drain out of the geyser.
  • Once the water has stopped flowing, close the hot water tap.
  • Only replace the drain plugs when you need hot water again.

We would also recommend you to flush with vinegar to remove scale build up. You will need:

  • 5-10 litres of standard vinegar
  • A submersible pump
  • 20 litre bucket
  • Washer/dryer hose set.

To flush your Paloma Gas Geyser with vinegar

  • Turn off the gas supply but leave the electricity supply on.
  • Turn off both water valves – no cold water in and no hot water out.
  • Unscrew the two drain plugs – one for the hot outlet and the other for the cold inlet, on the underside of the geyser, to drain all the water out.
  • Pour equal amounts of vinegar and water into a bucket so that the sub-pump is submersed in liquid.
  • Attach one side of the hose to the cold inlet.
  • Attach the other hose to the hot outlet and place the other end into the bucket to create a loop.
  • Run for at least half an hour.
  • After half an hour (take out the pre-filter to check it is clean).
  • Change the water in the bucket to clean water to flush out the vinegar.
  • Then remove the hoses, close the hot and cold water drain plugs.
  • Open the hot and cold water valves.
  • Turn the gas back on.

The use of Borehole Water will invalidate Paloma Gas Water Heater’s warranty. Please see more on our GWH warranty page
