To safe guard your property and to keep your pipes and geysers free of debris during water restorations after an outage, follow these tips.
- OPEN TAPS
- Residents are cautioned to keep taps closed, as a forgotten unattended open tap can lead to flooding or at least a waste of water when the water supply is restored. During leak tests or initial water restoration it can also allow dirt into your water pipes and fittings.
- The best way to keep as much dirt as possible out of your water system is to close the main stop valve at your water meter until water has been completely restored. You should still follow the water restore procedure below when you do open the stop valve.
- NOISES IN YOUR PIPES OR GEYSER
- While work continues and pressure and leak tests can be started and stopped at any time. This can cause some water to move through the system and combined with air (or the air being displaced) can cause noises in your pipes, geysers and toilets.
- It is recommended that you leave your geyser stop valve closed and your geyser switched off and only open it after following the hot water restoration tips below.
- A correctly installed geyser has numerous safeguards and will only explode if it is full of water & switched on and the thermostat & pressure relief valves malfunction leading to a catastrophic rise in pressure, beyond the tolerance of the geyser.
- RESTORING COLD WATER TO YOUR HOUSE
- The first rush of water will most probably contain a fair amount of dirt. It is recommended to keep the stop valve of your geyser closed and to first open a single cold water tap (preferably an outside tap closest to the main stop valve) to flush out as much dirt as possible. Once the tap is running clear, open the cold water tap the furthest away from the stop valve until that runs clear, and only then open you geyser stop valve.
- RESTORING HOT WATER TO YOUR HOUSE
Only when the water supply flowing from the cold taps is clean and stable should you open your geyser stop valve. Open a hot water tap to help air escape from the geyser. Once clean, air free water is flowing from your hot water tap you can switch your geysers trip switch back on.
- WATER FROM RELIEF VALVES
Do not be alarmed if you see water flowing out of relief valves in the streets. These are used to help keep pipes empty during work and also to bleed air from the system to minimize possible damage caused by the hammering of air rushing through the system when water is introduced into empty pipes.
- DON’T PAY FOR AIR
As water is restored air will rush through the pipeline and also through your water meter causing to spin up and increase the meter reading. To avoid this keep keep the main stop valve at your meter closed until water has been completely restored.
