A lead free tap is an excellent choice for those concerned about the safety of their water supply. Brass tapware is prone to lead exposure, which can be dangerous for the health of the user. This is why the Australian Building Codes Board is currently developing a new National Construction Code to protect people from lead exposure.
Lead levels in drinking water can be elevated due to a number of different reasons, including the type of plumbing in your home. Older faucets can contribute up to a third of the lead in the water. Other causes include copper plumbing with pre-1988 lead solder joints and lead-based service lines. If you're concerned about lead in your water, it's recommended to test your water for lead content before installing a lead-free tap.
One way to determine whether your home is at risk is to contact the local water utility. They should have public records for drinking-water service lines and may be able to provide you with this information. In addition, a licensed plumber can check plumbing fixtures for lead content. Moreover, you can consult your health department for more information if you use a private water supply.
If you live in a state that is committed to protecting its residents from the harmful effects of lead, the best way to ensure that your home is lead-free is to install a lead-free tap. Most states require plumbing products to be lead-free, as long as they meet the NSF/ANSI 61 standard. Copper and bronze plumbing fixtures should be lead-free as well, as these materials can contribute to lead contamination in drinking water.
