Sacrificial anodes have been around for years. The job of the sacrificial anode is to remove any electrical current that might be in a body of water. A sacrificial anode not only helps prevent electrical shock to a bather it also stops galvanic corrosion to your pool or spa equipment, heaters and any other metal fittings on your pool.
Why Do I Need A Sacrificial Anode
Over the years we have seen the introduction of some advanced technologies used in pool equipment, like multiple speed pumps, new heating systems, control systems that control multiple pumps, lights, blowers, motorised valves etc. We have self cleaning auto sanitisers, pH feeders, ultra violet disinfection systems that can all have an effect on pool and spa water. If your pool or spa is not correctly earthed at the pool equipment then stray current may enter the water. A Sacrificial anode when earthed correctly will remove any current entering the water.
Sacrificial Anode Installation
The sacrificial anode must be installed between into the water pvc pipe between the filter and before any equipment in that line, including a chlorination cell. See the diagram below as this displays a typical sacrificial anode installation on swimming pool equipment. In some cases a copper earthing stake may be needed depending on your pool spa installation.
Sacrificial Anode Features
Easy installation inline design for 50mm PVC pipework.
Prevents electrical shock to bathers and galvanic corrosion to pool and spa equipment and metal surfaces.
Electric shock protection for fibreglass pools.
Max 4 bar working pressure.
Long life cycle pure zinc alloy.
1 m 8 AWG solid copper wire and transparent lid cover for easy observation.
To test your pool or spa for electrical current you will need to speak with an electrician. Any electrician will be able to install the sacrificial anode and test your water to confirm your pool is current free.
