If you are living in an area that is well established, it is likely that the pipework underground has been there since the beginning. The test of time has not fared well on the older plumbing infrastructure around Australia and it is now becoming evident that lead and other heavy metals are leaching their way into the water. The introduction of Chloramine and Fluoride to Australian water has not aided this as it is known to wreak havoc on older pipes containing lead. Lead and other heavy metals are elements that you want to eliminate from the water before they enter your house. The H1-9LRC system is very similar to the H1-9CTO series in that it is great for the total elimination of VOC’s and Free Chlorine from the water supply but with the added feature of removing/reducing trace heavy metals in the water. The special Lead Reduction Composite material used in the LRC 4520-P5 Cartridge is effective at absorbing these metal contaminants from the water and providing your home with safe drinking water, free from lead, arsenic and other heavy metals.
