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.
